Scientists found something strange when they looked at the brains of pot smokers


Marijuana's official designation as a Schedule 1 drug – something with "no accepted medical use" – means it is pretty tough to study. Yet numerous anecdotal reports, as well as some studies, have linked marijuana with several purported health benefits, from pain relief to helping with certain forms of epilepsy. Still, experts say more rigorous scientific analyses are needed. Use of marijuana, a psychoactive drug, can come with risks, especially in people who may be prone to addiction or mental illness. And now, for the first time, researchers have found a link between daily decade-long weed use and a difference in how the brain processes reward.
