Legal cannabis linked to drop in anxiety medication prescriptions
Could legal marijuana be changing how we treat anxiety? A new study in JAMA Network Open reveals that in states with legal cannabis, fewer patients are filling prescriptions for anti-anxiety medications like benzodiazepines.
Adolescent cannabis use may heighten sensitivity to amphetamine’s cognitive effects in adulthood
Adolescent THC exposure in rat increased amphetamine-induced risky decisions in adulthood, particularly in females, without affecting overall cognitive flexibility.
New study links poor sleep quality to cannabis-related memory issues
New research reveals that disrupted sleep may be the hidden link between heavy cannabis use and memory deficits, unmasking an unexpected culprit behind cognitive impairments.
Shared genetic factors uncovered between ADHD and cannabis addiction

Cannabis use worsens reduced brain connectivity in young adults at risk for psychosis, study finds
Recent research found that young adults at risk of psychosis have reduced brain connectivity, and cannabis use worsens this issue, potentially disrupting brain development and increasing vulnerability to psychotic disorders.
Adolescent cannabis use and psychosis: Study finds shared risk factors and self-medication patterns

Brain structure and function differ in cannabis users, but genetic evidence suggests no direct causal link
Cannabis use is linked to changes in brain structure and function in older adults, but genetic analysis suggests these differences are likely due to other factors, not cannabis use itself.
Prenatal cannabis exposure linked to early childhood behavioral and cognitive challenges
Children exposed to cannabis before birth showed weaker attention, self-control, and planning skills in lab tests, along with more aggressive behavior.
New study provides first objective evidence of cannabinol’s potential to improve sleep
A compound found in cannabis, known as cannabinol, has been shown to enhance sleep in a new animal study.
Prenatal exposure to synthetic cannabinoid alters breathing and cardiovascular health in rats
Prenatal exposure to the synthetic cannabinoid WIN caused sex-specific respiratory control changes, fragmented sleep, and heightened cardiovascular risks in rats, highlighting potential long-term health concerns for offspring from cannabis use during pregnancy.
High-potency cannabis use leaves a distinct mark on DNA
High-potency cannabis use alters DNA methylation, impacting genes related to energy and immunity. These changes differ in psychosis patients, suggesting DNA markers may help identify users at higher psychosis risk and improve understanding of cannabis's biological effects.
CBD shows promise in managing fever and inflammation
A new study has found that cannabidiol (CBD) reduces fever in mice by decreasing pro-inflammatory markers and increasing anti-inflammatory responses, suggesting its potential as an alternative for managing fever and inflammation through immune system modulation.
Cannabis and alcohol use patterns linked to couples’ relationship quality
Heavy cannabis users report lower next-day relationship satisfaction when combining cannabis and alcohol. But light cannabis users show no significant change in satisfaction from their own or their partner’s substance use.
Cannabis use in early pregnancy not linked to ADHD or behavioral disorders in kids
A recent study found no increased risk of ADHD or disruptive behavior disorders in children by age 11 when mothers used cannabis early in pregnancy, though other maternal and newborn health risks remain.
Taking medicinal cannabis oil for insomnia does not impair cognition on the following day
A recent study found that a single dose of medicinal cannabis oil containing 10 mg THC and 200 mg CBD did not significantly impair next-day cognitive function or driving performance in adults with insomnia who infrequently use cannabis.
