Pretty much every drug can show up on a drug test. You have 5-panel and 10-panel drug test kits. The most extensive is the 12-panel drug test that checks for amphetamines, marijuana (THC), opiates, methamphetamines, phencyclidine (PCP), benzodiazepines, barbiturates, methadone, oxycodone, ecstasy, and propohyphene.
