Revised November 2013
New drugs and drug use trends often burst on the scene rapidly. NIDA’s Community Epidemiology Work Group (CEWG) is a network of researchers in major metropolitan areas and some states across the United States that reports data on emerging trends and patterns in drug use. On this page we will provide periodic updates based on CEWG reports and other reliable information, as well as links for where to go for more information.
E-cigarettes are increasingly popular battery-operated devices marketed as a safer alternative to smoking conventional cigarettes. They produce flavored nicotine aerosol that looks and feels like tobacco smoke but without the tar or other chemicals produced by burning tobacco leaves. However, while e-cigarettes do not produce tobacco smoke, it is still unclear how safe they are. They still deliver nicotine, which is a highly addictive drug. Also, vapor from some e-cigarette products has been found to contain known carcinogens and toxic chemicals. Until more studies are conducted, there is no way of knowing what the health consequences of repeated exposure to these chemicals may be, whether e-cigarettes are any safer than conventional cigarettes, or if they are useful to help a person quit smoking.

““Krokodil,” a toxic homemade opioid that has been used as a cheap heroin substitute in poor rural areas of Russia, has recently been featured in news reports alleging its appearance in parts of the United States. The CEWG is investigating, although the DEA has not yet confirmed any Krokokil in this country.
Krokodil is a synthetic form of a heroin-like drug called desomorphine that is made by combining codeine tablets with various toxic chemicals including lighter fluid and industrial cleaners. Desomorphine has a similar effect to heroin in the brain, although it is more powerful and has a shorter duration. Krokodil gets its name from the scaly, gray-green dead skin that forms at the site of an injection. The flesh destroyed by krokodil becomes gangrenous, and, in some cases, limb amputation has been necessary to save a user’s life.
We will update this page with any further information on Krokodil in the U.S., if cases are found.
“N-bomb” refers to any of three closely related synthetic hallucinogens (25I-NBOMe, 25C-NBOMe, and 25B-NBOMe) that are being sold as legal substitutes for LSD or mescaline. Also called “legal acid,” “smiles,” or “25I,” they are generally found as powders, liquids, soaked into blotter paper (like LSD) or laced on something edible.
These chemicals act on serotonin receptors in the brain, like other hallucinogens, but they are considerably more powerful even than LSD. Extremely small amounts can cause seizures, heart attack or arrested breathing, and death. At least 14 young people are reported to have died after taking 25I- 25C- or 25B-NBOMe between March 2012 and April 2013.

Drinking prescription-strength cough syrup containing codeine and promethazine mixed with soda was referenced frequently in rap music beginning in the late 90s and has now become increasingly popular among youth in several areas of the country, according to recent CEWG data. Codeine is an opioid that can produce relaxation and euphoria when consumed in sufficient quantities. Promethazine is an antihistamine that also acts as a sedative. Users may also flavor the mixture with the addition of hard candies.
Codeine and other opioids present a high risk of fatal overdose due to their effect of depressing the central nervous system, which can slow or stop the heart and lungs. Mixing with alcohol greatly increases this risk. Deaths from prescription opioid medications now outnumber overdose deaths from all other drugs (including cocaine and heroin), and codeine-promethazine cough syrup has been linked to the overdose deaths of some prominent rap musicians.

Molly—slang for “molecular”—refers to the pure crystalline powder form of the club drug MDMA (3-4 methylenedioxymethamphetamine), which in pill form is known as ecstasy. Molly, which is usually purchased in capsules, has seen a surge in interest in the past few years, being celebrated frequently by popular music artists. MDMA in any form produces energy and euphoria in users but also may dangerously affect body temperature and cause confusion, depression, and sleep problems.
Users may be seeking out Molly to avoid the adulterants or substitutes known to be commonly found in pills sold as ecstasy, such as caffeine, methamphetamine, and other harmful drugs. But those who purchase what they think is pure MDMA as Molly may actually be exposing themselves to the same risks. Hundreds of “Molly” capsules tested in two South Florida crime labs in 2012, for example, contained methylone, a dangerous stimulant commonly found in “bath salts” (see video below). News reports elsewhere have reported “Molly” capsules containing cocaine, heroin, and other substances.
