alcohol is an example of what type of substance?
depressant
hallucinogen
stimulant
opioid

Explanation:

1. Stimulants increase the release or activity of dopamine and act as agonists of the dopamine neurotransmitter system. Opioids act on opioid - receptors, hallucinogens affect serotonin and other systems, and depressants generally decrease neural activity and do not act as dopamine agonists.
2. Alcohol is a depressant as it slows down the central nervous system, reducing neural activity and affecting various functions like reaction time, judgment, etc. Hallucinogens cause hallucinations, stimulants increase activity, and opioids are related to pain - relief and have different receptor - targets.

Answer:

1. Stimulants
2. Depressant
