How long does THCA stay in your urine?

For occasional users, THC metabolites from THCA are typically detectable in urine for 3 to 7 days. For regular users, 10 to 15 days. For heavy daily users, urine tests can detect cannabis use for 30 days or more.

Does THCA show up on a drug test?

Yes. Once heated through combustion or vaporization, THCA converts into Delta-9 THC, which is what standard drug screens detect. Even raw THCA can metabolize into detectable compounds.

How long does THCA stay in your blood?

Active THC is detectable in blood for 1 to 2 days after a single use, and up to 7 days for chronic users. Blood tests are less common for routine screening but used in DUI investigations.

Does hair test detect THCA?

Hair follicle tests can detect cannabis use for up to 90 days, regardless of whether the source was THCA or Delta-9 THC, because both produce the same metabolites once processed by the body.
