Eh, depends on what strain of weed I smoke. Sativas make me talk fast and what not, and I sound like a retard. Indicas I like more anyways, because as an everyday smoker, I smoke a fair amount alone or with few company. Indicas slow my speech down noticably, but it's usually because I'm thinking of the right words to use. In any case, Indicas make me sound more intellectual, while Sativas make me sound the complete fool.
