Drug Test tomarrow, just a few q's So i have a drug test tomarrow to work at costco, they do a saliva test, I smoked about 3 days ago, but it had a little opium on it, I have been drinking tons of water, what are my chances? I haven't found much information about opiates and saliva testing, however i have seen that THC in saliva testing is gone 12-48 hours? can anyone confirm any of this information =D thank you!
