Half-life
The time it takes for the concentration of a compound like THC in the body to fall by half. THC's half-life varies widely with body fat and frequency of use, which is why it lingers in drug tests for days or weeks. It explains why effects fade gradually rather than abruptly.

- Onset
- The time it takes to feel effects after consuming cannabis. Smoking and vaping have an onset of minutes, while edibles can take thirty minutes to two hours as they pass through the gut and liver. Misjudging edible onset is the leading cause of accidental overconsumption.
- THC
- Tetrahydrocannabinol, the primary intoxicating compound in cannabis and the source of the classic "high." THC binds CB1 receptors in the brain, producing euphoria, altered perception, and appetite. Potency is listed as a THC percentage on most labels, though terpenes and dose shape the actual experience as much as that number.
- Tolerance
- The body's reduced response to cannabis after repeated use, requiring more product to feel the same effect. Tolerance builds fastest with daily high-THC use and resets with a break. Managing it through lower doses, rotation, or periodic abstinence keeps cannabis effective and your spending in check.
