What kind of drug test do most employers give pre-employment?

Many actually don't: Big companies may require drug testing before employment, but current many are not doing it, yet. That being said, the trend is increasing use of drug test before employment. Usually test for: marijuana, narcotics (morphine, percocet, vicodin, Methadone etc..), hypnotics (xanax, klonopin, (clonazepam) valium), cocaine, pcp, lsd, alchol. Best advice: just don't do it. Be good. Be safe. Be employed. Good luck.
