Ya, some people just have a low tolerance. I once worked with a guy who smoked for about twenty years. But he only ever smoked leaf trimmings cause if he smoked bud he'd get way too baked. You couldn't give him any bud, he'd offer to buy the trim. So, ya everyone's tolerance is different. It's just that if I don't notice myself getting a dry mouth, then the pot is not up to my, admitted high, standards.
