How exactly does Marijuana affect memory?

[-SD-]

Is it short term memory or long term memory that weed hinders? And if so for how long after you get high? Give me the lowdown since I smoke and dont want it to permanently affect my memory or my school work.

somebody answer my fucking question

I personally know 3 heavy users that are HIGHLY intelligent, 1 i've known since grade school and is working on a physicist degree and can make smoke pour out the chess computer. So who knows--cause i've also known some of the worlds biggest dumbasses to be smokers. If anything, I notice something wrong with them when they are NOT high. As long as your making the grade-I wouldn't be worried about it.

Marijuana seems to selectively inhibit short term memory formation in chronic users probably through an anti-cholinergic mechanism. However one paper found neuron death in the hippocampus in vitro due to direct exposure to THC. The hippocampus is a structure in the brain which is directly related to short term memory formation

what was the question?

I was a very heavy and chronic (5yrs.) user of the doja and went to a decent college and have always tested well. I've always considered a chicken-egg thing. You will find other studies that show an amelioration of cognitive deficits after discontinuation and no long term effects.
