You guys should calm down... you're eventually going to reach a point where it's pointless to smoke. I go through about 2 grams or less a week between myself and my girlfriend and another friend who we occasionally smoke with, although he throws down as well. I use a vaporizer and always get very high, but no longer feel the effects on me when I'm not actively high, except for the lack of vivid dreams when I smoke on a day. I break up about this much to put in the vaporizer, and it gets about 6 to 8 hits if the heat setting is right:

-\___/ (formatting this is hard)
I used to smoke an eighth every 3 days. That got expensive. Now I *ahem* obtain my own by means of paying my electric bill, so it's not really a factor anymore. But still, I wouldn't want to smoke that much. it's just silly. It's like you're having some sort of contest to see who's the biggest and baddest stoner. I used to play that game, but it's not worth it and it has a much bigger impact on your mental and physical state when you do it.
of course I'm talking about fine buds here, nothing less.
