Give it two more tries, and see if you still dont like it.

Its possible that pot just isnt for you. I have a friend who doesnt smoke anymore because everytime she does, she equates it to tripping on other unmentionable drugs that give fun visuals.

She just completely zones out for two to three hours, you cant talk to her or anything, and then she snaps out of it. So she just doesnt smoke with us anymore, and just enjoys some booze while we smoke.
