Chemical Dependency Counselor CCDC Exam Pharmacology & Drug Classifications 3

Question 1

Which neurotransmitter is most directly involved in the reward pathway that reinforces most substances of abuse?

Accepted Answer

Dopamine

Answer

Dopamine in the mesolimbic reward pathway is the primary neurotransmitter involved in the reinforcing effects of most abused substances, producing the 'high' that drives continued use.

Question 2

What is the primary danger of combining opioids with benzodiazepines?

Accepted Answer

Synergistic CNS depression leading to fatal respiratory failure

Answer

Both opioids and benzodiazepines are CNS depressants; their combination produces synergistic respiratory depression that dramatically increases the risk of fatal overdose.

Question 3

Stimulant withdrawal (from cocaine or amphetamines) is primarily characterized by:

Accepted Answer

Depression, fatigue, hypersomnia, and dysphoria

Answer

Stimulant withdrawal causes a 'crash' characterized by dysphoria, depression, extreme fatigue, increased sleep, and increased appetite as dopamine levels drop sharply.

Question 4

Which of the following is NOT classified as a DEA Schedule II controlled substance?

Accepted Answer

Alprazolam (Xanax)

Answer

Alprazolam (Xanax) is a Schedule IV controlled substance because benzodiazepines carry lower abuse potential than Schedule II drugs like morphine, cocaine, and methamphetamine.

Question 5

Naloxone (Narcan) reverses opioid overdose because it:

Accepted Answer

Rapidly displaces opioids from receptors as a competitive antagonist

Answer

Naloxone is a competitive opioid antagonist that rapidly displaces opioids from their receptors, reversing respiratory depression, sedation, and other overdose symptoms within minutes.
