As true as that might be, the person I was originally referring to was Helltooimp, who said that he saw things he'd never thought he would see when he "took" weed. For one, I've never heard anyone else say that they "took" weed, as that sounds pretty retarded. Two, he said that it made him smarter, which is clearly incorrect if you have read any of his posts.
My final point is, the guy is most likely full of shit, like most people who say they "trip" and "hallucinate" on weed. Under normal circumstances it just does not happen. I've never actually eaten anything that had marijuana in it but I've smoked shittons at a time and I've never hallucinated.
