there is tolerance, you can prove it by smoking constantly, weed just doesn't effect u as much.

but you are very right in what you said... when you use weed as a way to relax, to clear your mind, or just to get stoned its effects are noticed way more than when used to escape.

but as ive always said, i think its wrong to use pot to escape from or deal with you emotional problems. if you do this, you have an even bigger problem on your hands, you got a drug problem and a higher chance of psychological addiction.

but dont get me wrong here, whenever im pissed and depressed or anxious, i smoke a bowl. but i dont do it to just escape my problem. it calms me down so i can think of a real way to deal with or solve my problem
