How long does THC is detect in the blood system?

THC, the psychoactive component of cannabis, can typically be detected in the blood for up to 1-2 days after use for occasional users. For frequent or heavy users, THC may be detectable for a week or more. Factors such as metabolism, frequency of use, and the amount consumed can influence detection times. However, blood tests are less common than urine tests for cannabis detection, which can show THC metabolites for a longer period.
