I have an interesting question. Iv had various awsners to it as well... soo here we go... iv had this one bag of weed for about a month and a half (i like to stock up) and the other night i busted it open... i smoked my normal bowl that should get me messed up. To my dissapointment it didnt :( The stuff appears to have lil crystals on it and the like its just very dry at this point... i even smoked again that night to see if i could get high and aparently my bowl wasnt enough again. Soo by this point im a lil confused... now my question is this... could the weed possibly be old and not pack the punch it once did? Does weed even get old? Also is it the fact that iv been a stoner for 8 months now that my tollerance is different and i need to smoke significantly more weed to get high? Any input would be apreciated thanks. SmoKe on my Brotha's!
