During investigations into using transcranial brain stimulation (TMS) to treat cocaine abuse, two projects take diverging paths. One researcher moves to the next stage, while another is forced to cut his trial short.
Legally protected marijuana dispensaries (LMDs) were associated with lower rates of dependence on prescription opioids, and deaths due to opioid overdose, than would have been expected based on prior trends.

Teens who avidly seek new and intense sensations are more likely to start using substances, but are not more likely to use them regularly within the next 3 years unless they also are prone to devalue distant consequences and act impulsively.
Treatment that combines use of Bp/Nx and memantine may enable young adults addicted to opioids establish lasting abstinence after a relatively brief course of medication-assisted therapy, a pilot trial suggests.
Giving mice a modified version of a naturally occurring gene blocks cocaine’s stimulant effects without affecting the animals’ physiological or metabolic health. The new evidence advances the proposed therapy a step closer to readiness for testing in people.
