Repeated use of the recreational drug ecstasy (MDMA) is linked to sleep, mood, and anxiety disturbances, elevated impulsiveness, memory deficits, and attention problems that may persist for up to 2 years after stopping. Experimental studies in animals and humans indicate that MDMA damages serotonergic neurons. In a subset of humans, particularly adolescents, serotonin depletion from MDMA use may hasten or enhance vulnerability to a range of neuropsychiatric problems. The reviewed studies provide substantial evidence that MDMA causes neuronal damage, but more research is needed to determine if this destruction can have long-term or permanent neuropsychiatric consequences.

Pain reduces quality of life, health, and economic well-being. Opioids are effective analgesics but cause side effects and have contributed to an overuse crisis, prompting the search for new pain treatments. This review examines salvinorin A and its analogs, focusing on their structural and pharmacological profiles as a basis for developing safer analgesics. Ethnopharmacological reports and preclinical data show antinociceptive effects of salvinorin A and some analogs. Analogs modified at the C-2 position dominate the literature. Binding affinity correlates with chemical structure and in vivo effects. Salvinorin A's susceptibility to chemical modification makes it a valuable tool for probing cellular mechanisms and developing promising analgesic analogs, though more research is needed to confirm therapeutic potential.

After weekend ecstasy use, mood on Monday is lower than after non-use weekends. This effect is explained largely by more time spent in bed, which independently predicts lower mood. No differences were found in weekly depression or anxiety scores. The findings suggest that recovery-related behavior, not MDMA alone, may underlie post-use mood declines, though directionality cannot be determined.

Roland R. Griffiths was a highly influential scientist in behavioral and neuropsychopharmacology, known for his rigorous research on abuse liability of substances including alcohol, benzodiazepines, caffeine, tobacco, and psychedelics. This review, authored by his former mentees and collaborators, describes his methodical approach to research, his inclusive and collegial mentoring style, and his role in advancing scientific methods for abuse liability assessment, policy, and regulation. His work culminated in the establishment of the Johns Hopkins Center for Psychedelic and Consciousness Research, reflecting his curiosity-driven, humanity-serving science that continues to inspire innovation.

Kappa opioid receptor (KOR) binding availability in the brain was measured in living rats using positron emission tomography (PET) after administration of the KOR agonist salvinorin A. At lower doses, salvinorin A briefly competed for receptor binding but had no lasting effect. At a dose of 0.60 mg/kg, however, it induced a sustained decrease in KOR binding of 40–49% that persisted for up to 2.5 hours after the drug had left the brain, suggesting an adaptive response by the receptor not previously observed in vivo with PET.
