Buprenorphine Benefits Waitlisted Seekers of Opioid Treatment

March 2017

In two pilot clinical trials, buprenorphine helped participants reduce their illicit opioid use and injection drug use while awaiting admission to a methadone or buprenorphine treatment program. Researchers minimized the risks for improper use or diversion of the study medication by giving it to trial participants in a computerized, tamper-proof device that dispenses one dose each day.

Endocannabinoid Regulates Cocaine Reward

March 2017

  • Investigators have shown that 2-AG, an endocannabinoid (i.e., a cannabinoid manufactured within the body, as opposed to plant-derived), augments the cocaine-induced dopamine surge in the brain’s reward system.
  • The discovery adds to evidence that inhibiting activity in the endocannabinoid system might reduce cocaine’s rewarding and addictive effects.

Impacts of Drugs on Neurotransmission

March 2017

Drugs can alter the way people think, feel, and behave by disrupting neurotransmission, the process of communication between brain cells. This article discusses the central importance of studying drugs’ effects on neurotransmission and describes some of the most common experimental methods used in this research.

Promising Advances in the Search for Safer Opioids

February 2017

New studies show that two novel compounds powerfully suppressed animals’ pain responses, while producing little or none of the respiratory depression and liability for misuse and abuse associated with morphine and other typical opioids.

Prevention Program Reduces Substance Use By Participants' Friends

January 2017

The Strengthening Families Program for Youth 10-14 (SFP10-14), an evidence-based intervention that reduces teen substance use, also reduced participants’ friends’ substance use. Two factors that accounted for the nonparticipants’ reductions were less time spent by nonparticipants with their participating friends without adult supervision and improvements in nonparticipants’ attitudes toward substance use. The findings suggest that researchers should consider the potential for diffusion of benefits in designing and implementing prevention programs.

Nonmedical Treatment for Cocaine Addiction Shows Promise in Pilot Trial

November 2016

Patients who received transcranial magnetic stimulation (TMS) were more likely to abstain from cocaine than patients who received medications for symptoms associated with abstinence. Researchers concluded that TMS appears to be safe and its efficacy as a treatment for cocaine addiction deserves to be evaluated in a larger clinical trial.

Messages Shore Up Support for Making Life-Saving Anti-Overdose Medication Widely Available

October 2016

Public health messages can increase public approval for making naloxone legally available to friends and relatives of opioid users to administer if an overdose occurs.

Why Do People Lose Control Over Their Cocaine Use?

September 2016

Researchers monitored the activity of two types of neurons in mice: “urge” neurons, which promote feelings of reward and repeating behaviors that have produced rewards, and “control” neurons, which dampen those feelings and inhibit behavior.

Quinine as a Tracer for Medication Adherence

September 2016

Patients who don’t take their medications as prescribed often put themselves at risk for problems including misdiagnoses, complications, and death. A study suggests that adding low doses of quinine to patients’ medications could provide an inexpensive, reliable, and safe method of monitoring whether patients are taking their medications as directed.
