There's no set time frame for tolerance setting in, it's different for everybody. for the first year I got stoned out of my mind into utter incorherence. then the next half year I learned to handle it and and got normally high. now about 2 months after that year and a half, I can barely get high anymore regardless of how much I smoke. but my little brother, who started smoking 2 months ago, already has a tolerance as high as mine.

if you take a week off, there'll be a mild difference in your tolerance. basically the first high will be great again, the second a little less, the third you're right back where you started.

if you take a month off, you've probably got a week to a week and a half of better highs, though your tolerance will still be up, just not as much.

if you really want to get back to day 1, I'm not sure, but what I usually hear is 6 months off with most people.
