Nope... I've been rolling them lately cause my parents have some drums laying around. I don't smoke a shit ton, but I've been smoking about 2-3 a day for the past 2 months. For the longest time I smoked 2-3 times a week and got a big buzz, and I never got a tolerance build up. I either want to find a way to lower tolerance, or I'm going to have to break the current habit of smoking everyday and get it back to 2-3 a week. I don't know about anyone else, but the buzz from a cigarette is really euphoric, at-least it was when I wasn't doing it daily...
