SWIM smoked changa 4 days in a row (1 hit each night, SWIM knows this is a bit exessive), and the 3rd and 4th day the effects were diminishing.. is a tolerance built up with continued use? SWIM knows this is very likely the case but wanted to make sure SWIMs extraction wasn't quickly reducing in potency for whatever reason.. thanks

Tolerance is built up extremely quickly and disappears nearly as fast. An hour after smoking (or two at most), tolerance should not be an issue, unless there are other drug interactions involved that you haven't mentioned.
