How Long Does THC Stay in Your System After Quitting
Understanding the duration of THC in your system is crucial for those looking to quit. Learn about factors affecting THC detection and common detection times.
Cannabis Detection Times by Fluid
Urine tests typically detect THC for 3-30 days, blood for 1-7 days, hair for 90+ days, and saliva for 24-72 hours. Heavy users may extend these windows significantly. Factors like frequency, dosage, and metabolism influence detection periods.
Urine Testing
Most urine tests screen for THC metabolites. Occasional users detect in 3-5 days. Chronic users may test positive for weeks.

Blood tests find THC faster but detect shorter periods. Athletes and frequent users notice shorter windows due to active THC presence.

Hair Testing
