Not 100 percent if its true but ive always believed it does, because you speeds up your heart rate and stuff. It also makes you lazy and munch out so if your just getting stoned, eating, and sitting on your ass then i doubt you'd notice anything other than the numbers on the scale going up.
not true for me... at all.. when i used to smoke a lot i wouldnt be that hungry and when i did eat id gain a lot. when i STOPPED smoking i got so hungry all the time and i lost a lot of weight, and i ate like crazy
i've heard you get fat from eating while smoking. could be otherwise though. i have high metabolism as it is (inherited it from my grandpa) and i can eat ice cream every meal for a week and not gain a pound. i'm interested to see what happens to me.
i'll be trying pot this weekend and i'll try to post back later, once i figure out how it effects my metabolism/weight/etc.
