Cannabis: is usually out of the system for hair follicle testing within 3 mo. But if use was really heavy & long-term there have been cases where metabolites were picked up > 100 days after last use. Single use Marijuana might be detected in urine for 1 to 7 days (or more) &regular marijuana use can be detected in urine for 7 to 100 days .Single use THC may be found in blood for 12 to 24 hrs.
