im quite a lightweight even though ive smoked weed for awhile it doesnt take much to get me high... im not really sure what my limit is but when i smoke way to much i usually forget mostly what i did for that week. But my smoking session is propally like 6-7 good rips depending on how much weed i have left. But then and hour later i have so more than i fall asleep wake up then have some more its kinda like a cycle.
