Hey my name is Dee and I'm a former Bluelight forum member. I have switched to weed as an alternative to my coke and meth habits. I may also quit cigarettes but i have tried numerous times and i could not. I just have a small problem...My tolerance. Back when I was doing Meth and Coke I could function normally throughout the day. When I smoke I am not functional. If I even smoke .2 grams I am high as a kite for hours. how long till I can function normally after i smoke?
