Blood Drug Testing

My bf just got a saliva drug test and he smokes pot and uses opiates, will they show?

He smokes pot every day so I assume that will definitely show, right? He says he hasn't used opiates (heroin) for 5 days but I have a feeling he's lying. He may have used 3 days ago (he seemed like he was on it when I saw him that day). How long do these drugs stay in your saliva for a swab test?

1. yes.

3. If he hasn't used heroin in five days, it shouldn't show up on the drug test. Normal range for a saliva test is 2-3 days. The range for pot is usually, at a maximum, a day. So, he's probably got a decent shot at actually passing.
4. This is (usually) detection time by saliva test for heavy user Cannabis -1 hour after use, up to 14 hours Heroin, Cocaine, Meths- from time of use, for 48 to 72 hours Amphetamines,PCP- 3 days Codeine, Morphine -12 to 36 hours
