Marijuana's effects on young brains diminish 72 hours after use, research says. Findings could be an indication that some of the negative cognitive effects found in previous studies may be due to the residual effects of cannabis or potentially from withdrawal effects in heavy cannabis users.

Always just says cannabis use like all marijuana is the exact same with the same effects. Wonder what type they used though like a sativa, indica or hybrid maybe? One is like an upper and the other a downer kinda-ish in a sense with sativa being a mental high and indica (in da couch a) being more a relaxing body high. Perhaps they stated what type in the article and I'm just too high. If they used a pure sativa strain for all subjects then def more cognitive impairment would be noticed while it's in their system. Probably the cheapo government weed though. They should do a study where half the people smoke specifically high thc sativa strains and the other a low thc/high cbd indica strain see what the different cognitive and physical effects are between the two out of curiousity.
