i'd say a safe amount to smoke would be all of it. smoke it all and tomorrow buy some more.

actually, if you don't want to get to "that stage" then maybe you should only smoke with friends or something. because i used to smoke fairly infrequently but then i got a pipe and started toking up in my room, and i got to where i'd wake and bake and eat and bake and drive and bake and go to school and bake. its definitely a fun way of life, i think. its damn nice to go over to someone's house to buy weed and hitting the bong with them for a few hours before going home and smoking some more with your buddies there. whatever i'm stoned and rambling
