I start getting bored when my tolerance gets up to where smoking a bowl even out of my bong only gives me a buzz a little heavier than a cig would. I don't smoke cigarettes but I've smoke a few so. I just intentionally run out of bud take a week or so off, most currently a month long one. Now my tolerance is extremely low so it puts the fun back in it, i hadn't geeked out in a long time. Now i'll just get a bag and smoke probably twice a day at night until i run out and then wait around a week to get another bag so my tolerance stays low.
