I just took a 5 panel drug test will this show if I drank 3 days ago. And about how does it take parole to find out the results ?

The 5-panel tests for:

Cannabinoids Marijuana, Hash)
Cocaine (Cocaine, Crack, Benzoylecognine)
Amphetamines (Amphetamines, Methamphetamines, Speed)
Opiates (Heroin, Opium, Codeine, Morphine)
Phencyclidine (PCP)

Does not include alcohol. That must be separately tested for.

No knowledge of timing for agencies.
