holly shit dude... that used to happen to me all the time... i used to smoke every day for about a year and a hlaf and then it started to suck. I would usually be bale to get into conversations and shit. But then i just sat there and t hought i couldnt laugh or have a good time and i didnt know why.. it was hard for me to actually talk and when i did i thought i was saying the stupedist shit. Im on probation now and ihavent smoked untill the other night for 4 months.. i smoked and its still the same.. i think that i cannot get high anymore.. its like when i smoked by myslef i was fine i just did whatever but around people it was a different story..fucked up huh
