i think tolerance is how much you can handle at once. ive been almost everyday for 3 years and i can still get the high feeling off a bowl of schwag. it only lasts for maybe 10 minutes but its still a high. if i smoke a fat blunt of some dank, i will start to feel high after maybe 5 hits, but i can smoke it to the roach, and/or roll up another one right after.

also shwag highs make me shiver and give me headaches/paranoia, whereas good buds make me feel relaxed. it all depends on the person and the type of bud really
