Blood tests, unlike urinalysis, detect the presence illicit drugs, not inactive drug metabolites. In general, THC only remains detectable in the blood of cannabis consumers for a few hours (though low, residual levels may be detected in chronic smokers for up to 12-24+ hours if more sensitive technology is used).
Urine tests will also differ depending on the drugâs half-life but can detect most drugs for about two to four days. Drugs that can linger longer include marijuana and PCP. Hair tests generally reveal drug use between one week and 90 days after use.
