Recreational marijuana use is now legal in eight states plus the District of Columbia, giving public health researchers more leeway than ever to investigate some of the foundational underpinnings of cannabis culture: How much weed is in a joint? What happens to your brain when you get high?
And now: Are chronic marijuana users really more relaxed than everyone else?
You might be surprised to learn that the research to date on this question is mixed. One recent study found that while low doses of THC (the active chemical compound in pot) helped people cope with stressful situations, moderate to higher doses actually made people stress out even more.
But that particular study simply measured the effects of a single dose of THC – what about the effects of repeated heavy cannabis use?
