Introduction
Cannabis drug test cutoff levels are the threshold at which a drug test indicates the presence of THC, the psychoactive compound in cannabis.
Understanding Cutoff Levels
Cutoff levels vary depending on the type of test and the purpose. Standard cutoff levels range from 50ng/mL to 500ng/mL, with the most common being 50ng/mL for urine tests and 20ng/mL for saliva tests.

Implications of Cutoff Levels
Higher cutoff levels mean that it will take longer for THC to be detected, which can impact results if someone uses cannabis but doesn't test positive immediately. Lower cutoff levels result in faster detection, which can be useful in cases of frequent or acute cannabis use.
