FDA Special Announcement: Reports of Seizures After Using Nicotine Vaping Devices
Posted on April 04, 2019
(From the FDA web site) The FDA has become aware that some people who use e-cigarettes have experienced seizures, with most reports involving youth or young adult users. Seizures or convulsions are known potential side effects of nicotine toxicity and have been reported in the scientific literature in relation to intentional or accidental swallowing of e-liquid. However, a recent uptick in voluntary reports of adverse experiences with tobacco products that mentioned seizures occurring with e-cigarette use (e.g., vaping) signal a potential emerging safety issue. The FDA continues to monitor all adverse experiences reported to the agency about the use of e-cigarettes and encourages the public to report cases of individuals who use e-cigarettes and have had a seizure via the online Safety Reporting Portal, as further described below.
Seizures result from sudden, abnormal electrical activity in the brain. Though often associated with convulsions in which a person’s entire body shakes uncontrollably, not all seizures show full-body shaking. Other possible signs of seizures include a lapse in awareness or consciousness, which may look like a person is staring blankly into space for a few seconds or suddenly stops moving. The person may or may not fall down. Most seizures end in a few seconds or minutes, and the person may seem fine, sleepy, confused or have a headache afterwards. They may not remember what they were doing or what happened right before the seizure. While seizures generally do not cause lasting harm, they indicate the need for prompt medical attention to look for a cause and to prevent future seizures, if possible. If you think a person is having a seizure, call 911 and seek immediate medical help. For exposures with less serious visible effects or if you have questions, call poison control at 800-222-1222.

FDA Warns of Synthetic Cannabinoids Laced with Anticoagulant
Posted on July 26, 2018
The U.S. Food and Drug Administration issued a warning statement on July 19, 2018 about numerous health emergencies, mostly in midwestern states, caused by consumption of synthetic cannabinoid products laced with brodifacoum, an anticoagulant (blood-thinning) compound commonly used in rat poison. Hundreds of users of synthetic cannabinoid products typically sold in gas stations and convenience stores under various brand names such as "K2" and "Spice" have been treated for complications such as bleeding, and several people have died. Users of these products should be alert for bleeding and other symptoms like easy bruising, oozing gums, and nosebleeds and seek medical attention if they suspect they may have consumed contaminated drugs. Brodifacoum remains in the body a long time and can raise bleeding risk for weeks after consumption.

New York City Police Department Issues Alert on Synthetic Cannabinoid Products
Posted on May 21, 2018
The New York City Police Department (NYPD) has issued an advisory alert for residents in the Brooklyn North Borough Command, warning people about a toxic batch of K2 that has been linked to 49 overdose cases since May 18. The NYPD is investigating the specific source of the drug distribution and has made arrests.
Synthetic cannabinoids like K2 are human-made mind-altering chemicals that are sprayed on dried, shredded plant material so they can be smoked or sold as liquids to be vaporized and inhaled in e-cigarettes and other devices. These products are also known as herbal or liquid incense and are marketed under a wide variety of specific brand names, including K2 and Spice and often labeled “not for human consumption.”
Synthetic cannabinoids can cause serious mental and physical health problems including:
- rapid heart rate
- violent behavior
- suicidal thoughts
Officials urge citizens to call 9-1-1 immediately if they or someone they know are experiencing signs of overdose. For more information: http://nypdnews.com/2018/05/nypd-issues-k2-advisory-warning-brooklyn-residents/
Counterfeit “Oxys” Containing Dangerous Fentanyl in Mississippi
Posted on May 11, 2018
Police in Gulfport Mississippi have issued a warning to the public (May 7, 2018) about counterfeit Oxycodone tablets that look like regular “oxys” but are actually made of the dangerous synthetic opioid fentanyl. Analysis in a DEA lab revealed the pills contained no oxycodone at all. Pills containing fentanyl carry a high risk of overdose and death, especially if users are unaware of their actual content and are likely to take too many. For more information: http://www.gulfportpolice.net/notices/public-notice-oxycodone-fentanyl/
FDA Cites 40 Retailers for Violations Related to Youth Sales of JUUL E-Cigarettes
Posted on May 08, 2018
The Food and Drug Administration (FDA) has been conducting a nationwide effort to stop the sale of popular e-cigarette brands to youth, like JUUL, at brick-and-mortar stores and online retailers. Forty warning letters to various retailers were issued in April 2018. The JUUL brand is especially popular in youth and teens because it resembles a flash drive and is therefore difficult for parents and teachers to recognize. These products have high levels of nicotine and emissions that are hard to see. Reports show that teens are using and liking these products without knowing that they contain nicotine. This is problematic because we know that an adolescent brain is still developing, and early nicotine use can cause changes in the brain that result in continued use as an adult. Read more about the FDA press announcement.
FDA and FTC Take Action Against Manufacturers and Retailers Who Target E-Cigarettes to Youth
Posted on May 08, 2018
The National Poison Data System data between January 2012 and April 2017 indicates there were more than 8,000 e-cigarette and liquid nicotine exposures amongst children under six. Exposure to nicotine in children is especially dangerous and can result in serious harm or even death. The FDA has collaborated with the Federal Trade Commission (FTC) to warn companies about selling e-liquids used in e-cigarettes with advertising that resemble kid-friendly products.
Children are mistaking these products for juice boxes, cookies, or candy and consuming the products. The FDA is considering issuing product standards and other regulations on e-cigarettes and similar products, including limiting flavors that appeal to youth, implementing child-resistant packaging, and instituting strict product labeling. Read more about FDA and FTC’s actions.
Multiple States Issue Alerts on Synthetic Cannabinoid Products
Updated April 06, 2018
Update - Indiana and Wisconsin (April 6, 2018)
Indiana State Department of Health and Wisconsin Department of Health Services also issue a warning about the dangers of synthetic cannabinoid product use, reporting cases in their respective states in which synthetic cannabinoid product users experienced symptoms similar to those experienced in Illinois. Read more about the warnings from the Indiana State Department of Health and the Wisconsin Department of Health Services.
Update - Maryland (April 5, 2018)
The Maryland Department of Health and Maryland Poison Center issued a memorandum yesterday to Emergency departments, emergency medical services, health care facilities, and local health departments reporting on a case in central Maryland in which a user of synthetic cannabinoids was hospitalized with symptoms similar to those experienced by cases in Illinois linked to synthetic cannabinoid product containing a rat poison that acts as an anticoagulant. Read more about this memorandum from the Maryland Poison Center.
Additionally, the Illinois Department of Public of Health has issued a second warning on April 4, 2018, stating that they have now received reports of 81 cases. Read more about this updated alert from the Illinois Department of Health.
The Illinois Department of Public Health (IDPH) has reported 56 cases of users of synthetic cannabinoid products experiencing severe bleeding, likely due to contamination. In each case, hospitalization was required for coughing up blood, blood in the urine, severe bloody nose, or bleeding gums. Two people have died.
IDPH does not yet know which product or products are associated with the reported emergencies and deaths. Nine people tested positive for a lethal rat poison called brodifacoum that acts as an anticoagulant (causing bleeding), thus suggesting that the drugs had been laced with this substance. Synthetic cannabinoid chemicals, while potentially dangerous, are not known to cause bleeding. IDPH’s investigation is ongoing.
Synthetic cannabinoids are chemicals related to THC (the active ingredient in marijuana), but often more potent, that are sprayed on dried, shredded plant material so they can be smoked or sold as liquids to be vaporized and inhaled in e-cigarettes and other devices. These products are also known as herbal or liquid incense and are marketed under a wide variety of specific brand names.
IDPH is advising that anyone who has a reaction to synthetic cannabinoid products, such as severe bleeding, should call 911 or have someone take them to the emergency department immediately. Read more about this alert from the Illinois Department of Health.
FDA Investigates Multistate Outbreak of Salmonella Infections Possibly Linked to Kratom Products
Posted on February 21, 2018
The U.S. Food and Drug Administration (FDA) along with the Centers for Disease Control and Prevention (CDC) and state and local officials are investigating a multistate outbreak of Salmonella infections linked to products reportedly containing kratom. The CDC reports that 28 people ages 6 to 67 years in 20 states are infected, with 11 people who have been hospitalized. No deaths have been reported.
Salmonella bacteria cause the foodborne illness salmonellosis. Most people infected with Salmonella develop diarrhea, fever, and abdominal cramps. The illness usually lasts 4 to 7 days, and most people recover without treatment. However, in the current outbreak, an unusually high rate of cases have been hospitalized for their illness.
Kratom is a tropical deciduous tree native to Southeast Asia, with leaves that contain mitragynine, a psychoactive opioid. Kratom is consumed for mood-lifting effects, pain relief, and as an aphrodisiac. It is marketed in many forms, including leaves, pills, capsules, powder, and tea.
The FDA, CDC, and state and local officials are working to identify specific brand names or suppliers of products and will share more information as it becomes available. If you have questions about food safety, call 1-888-SAFEFOOD or consult the fda.gov website at http://www.fda.gov.
Iowa officials warn public about counterfeit oxycodone
Posted on July 18, 2017
Health and safety agencies in Iowa have issued an advisory to warn Iowans of counterfeit pain pills containing dangerous synthetic opioids. The Iowa Division of Criminal Investigation’s (DCI) laboratory analyzed pills made to resemble the prescription pain reliever oxycodone, finding them to contain more powerful and illicit synthetic opioids fentanyl and U-47700, putting users at higher risk of opioid overdose. Iowans with questions about synthetic opioids and emergency opioid reversal procedures can contact the Iowa Poison Control Center at 800-222-1222 or http://www.iowapoison.org.
More information is available from the Iowa Department of Public Health, Department of Public Safety, Poison Control Center and Office of Drug Control policy.
In Georgia: Sudden surge in overdoses related to street drugs sold as yellow opioid pain medication
Posted on June 29, 2017
The Georgia Department of Public Health has issued an alert about a dangerous, potentially lethal substance contained in street drugs surfacing in central and South Georgia. Patients reportedly purchased yellow pills alleged to be Percocet, an opioid pain medication. The substance has not yet been identified but it is extremely potent and has required massive doses of naloxone (Narcan) to counteract its effects. Dozens of patients have been hospitalized and there are reports of deaths that may be associated with the drugs. The overdoses have been reported over a 48-hour period in Centerville, Perry, Macon-Warner Robins, and Albany, but the drugs may also be sold on the street in other areas of the state. Testing is being done to identify the pills and the ingredients.
Health officials urge citizens to call 9-1-1 immediately if you have taken the pills or if you think someone has used the drug. Read the warning from the Georgia Department of Public Health.
New York City issues Health Advisory about overdoses from fentanyl added to cocaine
Posted on June 06, 2017
The New York City Health Department is warning citizens who use cocaine------even occasional users--- that the potent opioid fentanyl has been implicated in a growing number of cocaine-involved overdose deaths. In the past, fentanyl has been most commonly present in heroin-involved deaths, but fentanyl is increasingly being identified in overdose deaths involving other drugs. In 2016, 37 percent of overdose deaths involved cocaine and fentanyl without heroin, up from 11 percent in 2015.
Last year more than 1,300 New Yorkers died of a drug overdose, and nearly half (44 percent) of those deaths involved fentanyl In 2016. People who use cocaine occasionally and who are not used to taking opioids (i.e., have low tolerance) are considered to be at particularly high risk of overdose death. The NYPD Police laboratory testing data has confirmed the presence of fentanyl in with cocaine products as well as in counterfeit prescription sedatives (e.g., Xanax) and pain relievers purchased on the street, as well as in heroin, ketamine, and methamphetamine. Read the advisory from the New York City Health Department.
Gulf Coast HIDTA and the Georgia Bureau of Investigation Issue Synthetic Opioids Alert
Updated May 16, 2017
There have been two new alerts issued related to synthetic opioids. The Gulf Coast High Intensity Drug Trafficking Area has issued an alert for a substance with the street name “Grey Death.” The substance appears similar to concrete mixing powder and varies in texture, which ranges from a chunky rock-like material to a fine powder. It is not a single drug, but typically contains several potent opioids, including whatever a drug dealer has on hand in varying proportions. It has a potency much higher than heroin and is reportedly administered via injection, ingestion, insufflation, and smoking. The analysis of each grey death sample collected in the gulf coast region so far revealed the presence of three opioids: U-47700, heroin, and fentanyl; though the amount of each drug within grey death varied from sample to sample. (See Gulf Coast HIDTA Emerging Trend Bulletin: Potent new opioid/opiate compound known as “Grey Death" (PDF, 164KB))
In addition, the Georgia Bureau of Investigation (GBI) is issuing a public safety alert regarding illegal synthetic opioids that have caused more deaths in the first four months of the year than all of last year. In 2017, 17 deaths have been caused by the opioids U-47700 and/or furanyl fentanyl. U-47700 and furanyl fentanyl are both Schedule I drugs and used in the same manner as heroin. The drugs are distributed in either powder or tablet form. Furanyl fentanyl is a fentanyl analog and has been sold as a “designer” drug. (See Press release - GBI Issues Synthetic Opioids Alert)
DEA Temporarily Bans Synthetic Opioid U-47700 ("Pink"), Linked to Nearly 50 Deaths
Posted on November 15, 2016
The U.S. Drug Enforcement Administration (DEA) has temporarily classified U-47700, nicknamed "Pink," a schedule I drug, which means it has a high potential for abuse and no approved medical use. Since last year, this dangerous synthetic opioid has been linked with at least 46 confirmed deaths—31 in New York and 10 in North Carolina. Law enforcement agencies have seized the drug in powder form and as counterfeit tablets that mimic pharmaceutical opioids. Earlier this year, law enforcement in Ohio seized 500 pills resembling a manufacturer's oxycodone immediate-release tablets. However, laboratory analysis confirmed that they contained Pink.
Pink belongs to a family of deadly synthetic opioids far more potent than morphine. It is usually imported to the United States, mainly from illicit labs in China. The drug can be toxic—even in small doses. It is typically taken by itself or combined with other drugs such as heroin and fentanyl.
Pink's name comes from the pinkish hue of the powder. It has been available for purchase over the internet and is misleadingly marketed as a "research chemical." Labels that state "not for human consumption" or "for research purposes only" are likely used in an effort to avoid legal restriction.
For more information, see the DEA news release on its scheduling of Pink.
DEA Issues Nationwide Warning on Carfentanil
Posted on September 23, 2016
The Drug Enforcement Administration (DEA) has issued a nationwide warning to the public and law enforcement about human use of the potent animal opioid sedative carfentanil, one of the strongest opioids available. Carfentanil, a fentanyl analog with a potency approximately 10,000 times that of morphine, has been linked to a significant number of overdose deaths nationwide. It is used as a sedative or in general anesthesia for large animals, including elephants, but is not approved for use in humans. https://www.dea.gov/divisions/hq/2016/hq092216.shtml
In August 2016, NIDA posted carfentanil warnings by authorities in Ohio and Florida. As with many fentanyl analogs, it is likely that carfentanil is being added to mixtures of heroin and other street drugs, but it is not known how often carfentanil is being added to or substituted for other opioids in street drugs, underscoring its danger. More information can be seen under the August 23rd, 2016 posting below.
Fentanyl-Related Overdoses Prompt Alert from CDC
Posted on August 26, 2016
The Centers for Disease Control and Prevention (CDC) has released an alert to public health departments, health care professionals, first responders, and others through its Health Alert Network about the increase in fentanyl-related overdoses and deaths in many parts of the country. Fentanyl is an extremely potent synthetic opioid—50 times stronger than heroin. Traditionally, fentanyl and analogs such as carfentanil have been mixed with powder heroin. Fentanyl-laced heroin has been linked to a surge of overdoses in Indiana and Ohio in late August, 2016. Fentanyl and related compounds are also being found in counterfeit pills made to look like prescription pain relievers and sedatives (e.g., OxyContin®, Xanax®, Norco®). These counterfeit pills are also the subject of a recent Drug Enforcement Administration alert.
Those who use heroin or prescription drugs laced with fentanyl are at much higher risk of overdose and death. When emergency personnel are able to respond in time, they sometimes need multiple doses of naloxone to reverse fentanyl overdoses.
Alert Issued in Ohio for Human Use of Animal Sedative Carfentanil, with Cases Also Seen in Florida
Posted on August 23, 2016
Officials in the Cincinnati area (Cuyahoga County) have issued an alert about human use of the potent animal opioid sedative carfentanil, one of the strongest opioids on the market, with a potency approximately 10,000 times that of morphine and 100 times that of fentanyl. Carfentanil is an analog of the synthetic opioid analgesic fentanyl and is used as a sedative or in general anesthesia for large animals, including elephants. Side effects of fentanyl analogs in humans are similar to those of fentanyl itself, which include itching, nausea, and potentially serious respiratory depression, which can be life-threatening. Officials in Ohio have noted a high number of overdoses in a short period of time that are suspected to be from carfentanil. NIDA’s National Drug Early Warning System (NDEWS) reports several confirmed deaths in Akron and Columbus, and numerous seizures of the drug throughout Ohio. Read the public health warning from Cuyahoga County, Ohio.
In Florida (Manatee County), there was a recent seizure of carfentanil and a coincidental increase in overdoses and deaths. While more than a dozen fentanyl analogs are commonly flagged in postmortem testing in many states, it is difficult to assess how commonly carfentanil is being abused because states have few reference materials on this drug and few labs are equipped to test for it. The forensic toxicology laboratory researchers at the University of Florida are currently developing a new assay for the identification of carfentanil and will soon start including it in postmortem overdose death testing. Laboratory personnel are being warned about the potency of the drug and are advised to handle it with great care. Naloxone (Narcan®) should be available in the case of accidental exposure.
As with many fentanyl analogs, it is likely that carfentanil is being added to mixtures of heroin and other street drugs. Currently, it is unclear how often carfentanil is being added to or substituted for other opioids in street drugs, underscoring the risks of using illegal drugs.
More information can be found at the National Library of Medicine's Pubchem database – carfentanil.
Fake Prescription Drugs Laced with Fentanyl
Updated July 28, 2016
The Drug Enforcement Administration reports that the United States is in the midst of a fentanyl crisis, as traffickers are flooding the drug market with counterfeit prescription drugs containing fentanyl, an extremely powerful opioid. These pills, which look like legitimate prescription pain relievers or sedatives, are causing large numbers of fatal overdoses in many parts of the country. Because of its high potency, fentanyl is deadly in very small doses; it is even hazardous for law enforcement, as a lethal dose can be accidentally inhaled or absorbed through skin contact. For more information, see the DEA report - Counterfeit Prescription Pills Containing Fentanyls: A Global Threat (PDF, 3.1MB).
Media reports and official alerts in several U.S. communities (including Sacramento, CA and most recently, Carroll County, MD) are warning of counterfeit pain and anxiety medications that actually contain fentanyl, an extremely powerful, potentially deadly opioid. The pills, which are disguised as common prescription drugs like Norco (hydrocodone), Percocet (oxycodone), and Xanax (alprazolam), are responsible for a growing number of overdose deaths and non-fatal overdoses around the country. Fentanyl is 25 to 50 times stronger than heroin, so even a small amount can cause an overdose. (The Drug Enforcement Administration reports that some of these pills are manufactured in China and smuggled into the U.S. via Mexican drug cartels.)
The fake pills are much cheaper than the real versions. The public should be aware that drugs obtained on the street, even though they look like a real prescription pharmaceutical, may be deadly. It is always unsafe to take a prescription drug unless it comes from your own prescription and is dispensed by a reputable pharmacy.
Synthetic Cannabinoid Advisory in New York City
Posted on July 16, 2016
On July 14, 2016, New York City health officials issued an advisory about an increase in adverse events and emergency department visits related to synthetic cannabinoids (K2/Spice). From July 11 through July 13, 130 people were taken to emergency rooms after suspected ingestion of these drugs, which are sold under many street names including Geeked Up, Smacked, Scooby Snax, Green Giant, Red Giant, M. Bad Guy, Trippy, Ice Dragon, AK-47, and Kick. Synthetic cannabinoids, sometimes called "fake weed" or "herbal incense," are chemically related to THC, the active ingredient in marijuana, but they may be much more powerful. Their effects can be unpredictable and have caused death in some cases. In recent cases in New York City, some users' overdoses resemble opioid overdoses, including lethargy and suppression of breathing; in other cases they have exhibited agitated and violent behavior. The increase in emergency room admissions might indicate that the K2/Spice products circulating in the New York City area might be laced with other toxic chemicals. View Advisory (PDF, 61KB)
For more information on synthetic cannabinoids, see DrugFacts: K2/Spice ("Synthetic Marijuana")
Posted on June 09, 2016
Loperamide is an over-the-counter anti-diarrheal medication that is available in tablet, capsule, or liquid form under brand names such as Imodium, Kaopectate 1-D, Maalox Anti-Diarrheal, and Pepto Diarrhea Control. Because it acts at mu-opioid receptors, which regulate movement in the intestinal tract, it is an opioid medication, and there are reports of its being misused by drug users to stave off opioid withdrawal or possibly even to get high.
Misuse of loperamide has been reported since 2003; it is not common, but it has been reported all over the country. Nationwide, the number of calls to poison centers involving the intentional abuse or misuse of loperamide increased from 87 in 2010 to 190 in 2014 (AAPCC annual reports; http://www.aapcc.org/annual-reports/).
Effects of Loperamide
When taken as recommended, loperamide is designed not to enter the brain; but instructions available on the Internet purport to show how taking loperamide in very high quantities and combining it with other substances may help it produce psychoactive effects that resemble the euphoric effects of other opioids or that mitigate cravings and withdrawal symptoms.
Users’ reports of these effects (if any) are conflicting, but physical consequences of loperamide misuse may be severe, including fainting, abdominal pain, constipation, cardiovascular toxicity (including racing heart and even cardiac arrest), pupil dilation, and kidney failure from urinary retention. Anecdotes and case reports indicated that the potential harm is high.
There were also reports of opioid withdrawal symptoms when users stopped taking loperamide, including severe anxiety, vomiting, and diarrhea.
FDA issued a Safety Alert about Loperamide on 6/7/16: Loperamide (Imodium): Drug Safety Communication - Serious Heart Problems With High Doses From Abuse and Misuse
More information on loperamide is also availabe from the National Drug Early Warning System (NDEWS).
Surge in Fentanyl Overdose Deaths
Posted on July 09, 2015
A surge in overdose deaths related to fentanyl, an opioid 30 to 50 times more potent than heroin, has prompted Baltimore health officials to launch a public health campaign to raise awareness among drug users. Hundreds of people have overdosed on fentanyl across the nation since 2013, often as a result of using heroin that has been laced with the much stronger substance. A quarter of drug overdose deaths in Maryland now involve fentanyl, up from 4 percent in 2013. Opioid overdose can stop a person's respiration, and fentanyl can have this effect very quickly. Other parts of the country such as Detroit and surrounding suburbs are also seeing major surges in fentanyl use and fentanyl-related deaths. In some cases users are unknowingly taking fentanyl in what they believe to be pure heroin, but a growing number of opioid users are deliberately taking fentanyl.
Fentanyl and other opioid overdoses can be reversed if the drug naloxone (Narcan) is administered promptly. In a growing number of states, naloxone is being distributed to injection drug users and other laypersons to use in the event of overdose. For example, Baltimore's Staying Alive Drug Overdose Prevention and Response plan issues naloxone and training in its use.
Increasing Overdoses From Synthetic Cannabinoids (“Spice,” "K2,” etc.) in Several States
Updated May 08, 2015
Recent surges in hospitalizations and calls to poison control centers linked to consumption of synthetic cannabinoid products--sold under brand names like “Spice,” “K2,” "No More Mr. Nice Guy," and others--are being reported in several southern and northeastern U.S. states and have prompted officials to issue health warnings. After a surge in synthetic cannabinoid exposures and poison center calls in April and May, 2015, the Maryland Poison Center issued an urgent notice about the dangers of these drugs. New York Governor Andrew Cuomo issued an alert after more than 160 patients were hospitalized following synthetic cannabinoid use in under two weeks in mid April, 2015.
Synthetic cannabinoids are chemically related to THC, the active ingredient in marijuana, and are sometimes called “synthetic marijuana” or “legal marijuana,” but actually the effects can be considerably more powerful and more dangerous than marijuana. Users can experience anxiety and agitation, nausea and vomiting, high blood pressure, shaking and seizures, hallucinations and paranoia, and they may act violently.
The Maryland notice lists several chemical compounds in materials from crime labs, including MAB-/AB-CHMINACA, FUBINACA, FUB-PB-22, and XLR11. Besides the brand names above, the New York State health alert lists other common names: Blonde, Summit, Standard, Blaze, Red Dawn X, Citron, Green Giant, Smacked, Wicked X, AK-47; recent reports have involved products with the names Geeked Up, Ninja, Caution, Red Giant, and Keisha Kole.
For more information on synthetic cannabinoids, see DrugFacts: K2/Spice ("Synthetic Marijuana")
U.S. and British Columbia Issue Alerts on Fentanyl
Updated March 18, 2015
The U.S. Drug Enforcement Agency (DEA) has issued a nationwide alert about the dangers of fentanyl and related compounds (fentanyl analogues). Fentanyl, an opioid that is 50-100 times more powerful than morphine, is both abused on its own and commonly added to heroin to increase its potency. Fentanyl and fentanyl-laced heroin have been a concern for over a decade and have caused numerous overdose deaths among injection drug users in several U.S. cities.
Heroin is not the only drug that can be laced with fentanyl, however. Officials in Vancouver, British Columbia, Canada, recently issued public warnings about a wide range of fentanyl-laced drugs causing overdose deaths among users. They warn that fentanyl is now being concealed in non-injection drugs, including oxycodone and various "party drugs" in powder or pill form, as well as in marijuana (although no deaths have been confirmed from fentanyl-laced marijuana). Because of this new threat, British Columbia officials are urging all recreational drug users to "know their source."
2019 Update: There have been no subsequent reports of marijuana laced with fentanyl since this was first reported by a variety of police agencies in 2015. Initial reports were difficult to verify; NIDA continues to monitor drug use reports through our regional National Drug Early Warning System and other national, state and local channels.
HIV Outbreak in Indiana Linked to Abuse of Opana
Posted on February 27, 2015
Health officials in Indiana have announced a fast-spreading outbreak of new HIV cases in the southeastern portion of the state that are linked to injection drug abuse of the powerful prescription opioid painkiller Opana. Injecting drugs and sharing injection equipment is one of the main routes of transmitting HIV. Also, a few new HIV cases in southeastern Indiana were transmitted sexually.
Officials advise that people in southeastern Indiana who have engaged in needle sharing or unprotected sex should get tested for HIV and then re-tested after 2-3 months, as HIV may not appear on tests immediately when the virus is contracted. To reduce risk of contracting HIV, avoid injection drug use, sharing or re-using needles, and having unprotected sex or sex with commercial sex workers.
New Synthetic Cannabinoids—“Cloud 9,” “Mojo,” etc.

Makers of designer drugs that are chemically similar to marijuana’s active ingredient THC—called synthetic cannabinoids or colloquially “synthetic marijuana” or “synthetic pot”—are constantly creating new products to evade legal bans on older compounds. Despite the similarity on the molecular level, these drugs are much more dangerous than marijuana, and have resulted in very serious health consequences including overdoses and aggressive or suicidal behavior in users.
Some new compounds have recently emerged that are sending many users to the hospital in cities around the country. They include:
- AB-PINACA, AB-FUBINACA (sold as “Cloud 9,” “Relax,” or “Crown”) is sold as a liquid in eyedropper bottles and often used with vaporizing devices—e-cigarettes or “hookah pens.” Numerous hospitalizations in Michigan prompted the Macomb County Health Department to issue an emergency warning and ban on the sale of these drugs, which are reported to cause hallucinations, aggressive behavior, racing heartbeat, drowsiness, and vomiting.
- MAB-CHMINACA, ADB-CHMINACA (sold as “Mojo,” “Spice,” “K2,” and “Scooby Snax”) resulted in over 150 hospital visits in Baton Rouge and Lafayette, LA in October, prompting the governor to ban the drug in that state. It is reported to cause severe agitation, anxiety, and paranoia; raised heartbeat and blood pressure; nausea and vomiting; muscle spasms, seizures, and tremors; intense hallucinations and psychotic episodes, including suicidal fixations and other harmful thoughts.
