Substance use disorders

[Michiko]

Substance use disorders generally involve behavior patterns in which people continue to use a substance despite having problems caused by its use.
The substances involved tend to be members of the 10 classes of drug that typically cause substance-related disorders:

Alcohol
Antianxiety and sedative drugs
Caffeine
Cannabis (including marijuana and synthetic cannabinoids)
Hallucinogens (including LSD, phencyclidine, and psilocybin)
Inhalants (such as paint thinner and certain glues)
Opioids (including fentanyl , morphine , and oxycodone )
Stimulants (including amphetamines and cocaine)
Tobacco
Other (including anabolic steroids and other commonly abused substances)

These substances all directly activate the brain
