you'll get tested for sure on the NIDA (National Institute for Drug Abuse) 5.

that includes:
1. Marijuana
2. cocaine
3. amphetamines
4. opiates
5. Phencyclidine (PCP)

you may also be tested for:
1. Barbiturates (Phenobarbital, Secobarbitol, Butalbital)
2. Hydrocodone (Lortab, Vicodin)
3. Methaqualone (Qualuudes)
4. Benzodiazepines (Valium, Xanax, Librium, Serax, Rohypnol)
5. Methadone
6. Propoxyphene (Darvon compounds)
7. Ethanol (Alcohol)
8. MDMA (Ecstasy)

Lastly, the drugs that are tested for only about 6% of the time are:
1. LSD
2. Tryptamines (Psilocybin, AMT, DMT, DPT, 5-MeO-DiPT)
3. Phenethylamines (Mescaline, MDMA, MDA, MDE, 2C-B, 2C-T-7)
4. Inhalents (Toluene, Xylene, Benzene)


Completely safe drugs:
1. 2c-i (a research chemical that mixes the effects of X and acid)
2. DXM (not recommended, can cause liver damage, and not a very good trip)
3. alcohol is relatively safe, it only lasts in your system for 12-24 hours after you drink
4. Salvia is still completely legal, although i don't really recommend that either

that's all i've got for you, i hope that's useful
