Tolerance

Reset a few days for acute effects

Tolerance Decay

Full tolerance 2d Half tolerance 7d Baseline ~14d

Rapid escalation in a single session is common due to short duration and fiendishness, particularly when vaporized. Several days to weeks of abstinence are typically needed to approach baseline sensitivity. Data quality primarily anecdotal.
