Detection surrounded by saliva tests begin immediately upon use:
For Marijuana and Hashish (THC): 1 hour after ingestion, for up to 24 hours
For Cocaine (including crack): From time of ingestion for 48 to 72 hours
For Opiates: From time of ingestion for 48 to 72 hours
For Methamphetamine and Ecstasy (MDMA, "Crank," "Ice"): From time of ingestion for 48 to 72 hours
