I have smoked weed heavily in my late 20s, ingested many types of edibles, topicals, etc. I am certainly not as sharp as I used to be. It can cause brain damage indirectly due to changes in your cardiovascular system. It can mimic a temporary sort of vascular dementia, as well as increase your blood pressure to very unsafe levels. Weed can also reduce the amount of grey matter in your orbitofrontal cortex. Not to mention the somewhat bizarre cartoon-like images you see on high doses of edibles. These images can fracture your mind if you see them enough. The risks are very real, and trying to downplay them or censor them is extremely irresponsible.
