actually cannabis falls into the same category o' drugs as alcohol or this other one (shoulve studied more at bio) teh inhibitory ones i think
and what they do is stop the nervous electrical circuits by blokin teh receptors (as a generaliztion), cannabis blocks them by replacing them....
i guess, at least thats what they told me in bio

case is yeah, it slows ur heart rate down it doesnt litterally depress u, normally some ppl take weed BECOUSE they are depressed in the first place, then they get more depressed becouse of their life not becouse of weed, and they blame it on the weed....... sux, gives weed a bad rep
