Regular pot smokers have shrunken brains, study says

That warm buzz may be dissolving frontal cortex neurons. Or not: Maybe fewer neurons there came first - LA Times

Experimental mice have been telling us this for years, but pot-smoking humans didn't want to believe it could happen to them: Compared with a person who never smoked marijuana, someone who uses marijuana regularly has, on average, less gray matter in his orbital frontal cortex, a region that is a key node in the brain's reward, motivation, decision-making and addictive behaviors network.
