Children whose mothers use marijuana are more likely to try it at younger age

When mothers use marijuana during the first 12 years of their child's life, their cannabis-using children are more likely to start at an earlier age than children of non-using mothers, according to a new study. This study is the first to establish a relationship between maternal cannabis use during a child's lifetime and earlier initiation in a nationally-representative, longitudinal cohort.

Octopuses given mood drug 'ecstasy' reveal genetic link to evolution of social behaviors in humans

By studying the genome of a kind of octopus not known for its friendliness toward its peers, then testing its behavioral reaction to a popular mood-altering drug called MDMA or 'ecstasy,' scientists say they have found preliminary evidence of an evolutionary link between the social behaviors of the sea creature and humans, species separated by 500 million years on the evolutionary tree.

Drug overdose epidemic has been growing exponentially for decades

Death rates from drug overdoses in the US have been on an exponential growth curve that began at least 15 years before the mid-1990s surge in opioid prescribing, suggesting that overdose death rates may continue along this same historical growth trajectory for years to come. These findings suggest that, to be successful, prevention efforts must extend beyond control of specific drugs to address deeper factors driving the epidemic.

Sugar pills relieve pain for chronic pain patients

Someday doctors may prescribe sugar pills for certain chronic pain patients based on their brain anatomy and psychology. And the pills will reduce their pain as effectively as any powerful drug on the market, according to new research. Scientists have shown they can reliably predict which chronic pain patients will respond to a sugar placebo pill based on the patients' brain anatomy and psychological characteristics.

Increased cortical activation in cannabis users' brains in resting state, research suggests

Recent research shows that cannabis users experience increased cortical activation during the brain's resting state when compared with nonusers. The resulting 'noisy brain' might impair brain activity and disrupt cognitive processes, say researchers.
