Well first it depends on all of your individual tolerances, then, how potent the herbs are. Let's say you're an everyday smoker like me and most of my smoking buddies, 2 grams of some Pretty frosty hydro ( from Boston @ $45-50 an eigth) would blaze me for about an hour tops. After that, RELOAD!

I do need to take some time off to lower my tolerance......
