well when i stopped for a little more then 2 weeks my tollerance went way down. but it only lasted for the first like 5 times of smoking again. then the tollerance was back to the way it was b4. i definatly go really really high teh first couple of times blazing and i did feel different after not smoking for a week. my advice is to just slow down or alternate days of smoking. that will keep your tollerance lower but not as low as u want it, and save you some money.
