Blood testsâ effective ranges will vary based on the half-life of the drug but are generally sensitive for about one to three days.[1] Marijuana edibles will linger longer, for up to seven days. Saliva tests range depending on the drug, but most can detect drugs used in the last 12 hours to three days.
