a large tightly-packed bowl will get me pretty high, and i've been steadily (as in pretty much daily) smoking mid for months. C is right, the more you smoke the more you begin to appriciate it and get the most out of your high and learn how to smoke with extreme efficiency. i haven't noticed any major tolerance, as it still doesn't take too much to get me high. in fact, i still can't even finish a blunt by myself in a single sitting.... i can barely smoke half of one before i decide to put it out and save the rest for later
