Alcohol is an intoxicating ingredient found in beer, wine, and liquor that acts as a depressant to the central nervous system. Heroin is considered the fastest-acting opioid, taking effect nearly immediately and making it extremely addictive, the Drug Enforcement Administration (DEA) warns. Gable, R. (2004).

Because more of these neurotransmitters remain active in the brain, the result is an increase in the activity of the sympathetic division of the autonomic nervous system (ANS).
