*THC half life for frequent users may be 3-13 days
Note: Elimination half-life is the length of time required for the concentration of a drug to decrease to half of its starting dose in the body. After 4 to 5 half -lives, 94 to 97% of a drug will have been eliminated and the plasma concentrations will be below a clinically relevant concentration.
See https://www.ncbi.nlm.nih.gov/books/NBK554498/ for more information.
The plasma half lives listed are based on averages. Reference: Disposition of Toxic Drugs and Chemicals in Man,(9th Edition) by Randall C. Baselt
