Answer 1

The DSM-5 lists ten major substance classes: Alcohol, Cannabis, Opioids, Stimulants, Tobacco, Hallucinogens, Inhalants, Sedatives, Hypnotics, Anxiolytics, and Caffeine. These classes are based on how the drugs affect the brain and alter mood, perception, and behavior.

Step-by-step explanation:

According to the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), there are ten major classes of substances that may lead to substance use disorder. The correct classes of substances are:

1. Alcohol
2. Cannabis
3. Opioids
4. Stimulants (including cocaine and amphetamines)
5. Tobacco
6. Hallucinogens
7. Inhalants
8. Sedatives
9. Hypnotics
10. Anxiolytics
11. Caffeine

These classifications are based on the pharmacological effects the drugs have on the brain and corresponding changes in mood, thinking, perception, and/or behavior. For example, stimulants like cocaine and amphetamines increase alertness, while depressants such as alcohol and opioids have a calming effect and can induce sleep. Anxiolytics, which include benzodiazepines, have a tranquilizing effect and inhibit anxiety. It's important to note that some psychoactive drugs can have multiple effects and may fit into more than one class.
