TL;DR: Functional imaging is investigated using functional imaging to examine neural activity in cigarette smokers, the most prevalent substance-dependent population in the United States, as they used cognitive strategies to regulate craving for cigarettes and food, suggesting that it involves neural dynamics parallel to those involved in regulating other emotions.

TL;DR: The Johns Hopkins-Lancet Commission on Drug Policy and Health as mentioned in this paper examined the emerging scientific evidence on public health issues arising from drug control policy and to inform and encourage a central focus on health evidence and outcomes in drug-policy debates, such as the important deliberations of the 2016 UNGASS on drugs.

TL;DR: Two placebo-controlled, within-subject studies investigated the effects of a cannabinoid agonist, delta-9-tetrahydrocannabinol (THC), and a mood stabilizer, divalproex, on symptoms of marijuana withdrawal, suggesting that oral THC, but not divalProex, may be useful in the treatment of marijuana dependence.

TL;DR: It is demonstrated that acute marijuana smoking produced minimal effects on complex cognitive task performance in experienced marijuana users.

TL;DR: A critical review of findings from recent research investigating the impact of recreational methamphetamine use on human cognition, including findings from studies that have assessed the acute and long-term effects of methamphetamine on several domains of cognition, finds that methamphetamine improves cognitive performance in selected domains, including visuospatial perception, attention, and inhibition.
