National Certified Addiction Counselor, Level I (NCAC I) Practice Exam

Barbiturates are primarily classified as depressants because they work by slowing down the central nervous system. This class of drugs enhances the effects of the neurotransmitter gamma-aminobutyric acid (GABA), which leads to sedative, hypnotic, and anxiolytic effects. Consequently, barbiturates are often used to induce sleep, relieve anxiety, and provide sedation during medical procedures.

In the context of addiction counseling, understanding the classification of barbiturates is critical, as this knowledge can help professionals recognize the risks and potential consequences associated with their use, including dependency and overdose. Recognizing barbiturates as depressants also allows counselors to better assess and treat clients who may be struggling with substance use involving these drugs.
