Positive THC confirms use of THC within 24 hours or less. Kissing some who is smoking Marijuana will not reveal a positive +THC test after 30-60 minutes, so always wait one hour before oral testing. Blood: Can have high peak plasma concentrations of 100-200 ng/mg on recent usage but rapid elimination occurs so may be negative in 24-48hour. ................
