The only way that could ever happen is if you took like a few day break every few weeks.
But I like to smoke to much to do that. And I know my tolerance will go up.

Maybe a 2 day break will bring it down a lil' bit...

Used to be 1/4th of a bowl could get me high, then 1/2 a bowl, now a full bowl to 1 1/2 bowls... Oh well... *shrugs*
