so when i smoke pot, people have told me that if i was not speaking clearly,so that it looks like i am having a seizure, which last up to 2 hours. it really frightens people. i stoped smoking it myself, but my friends still do. i found out the hard way that i get the same reaction from second hand smoke, except this way, the twitches are painful. i can actually feel my muscles getting tense from these long periods of twitching, and i usually end up needing someone to hold me down to get any relieve. is this something i shoud be concerned about? is it possible to have seizures in reaction to pot?
