Questions and Answers

Which of the following is NOT one of the variables that determine the addictiveness of a drug?

Rate of clearance from the body (correct)
Extent to which the drug stimulates the reward system
Rate of entry into the bloodstream
Level of reward system stimulation

Why is a faster rate of onset more addicting?

Because it clears from the body more quickly
Because it stimulates the reward system more intensely
Because it causes a stronger association between drug and feeling better (correct)
Because it creates a higher peak blood concentration of the drug

What does the contrast phenomenon refer to?

The formation of addictive behavior in drug addicts
The rate of entry of a drug into the bloodstream
The rate of clearance of a drug from the body
The contrast in the change of the drug levels in our bloodstream (correct)

What are the four features that determine the addictiveness of a drug?

What is the contrast phenomenon?

The contrast phenomenon refers to the phenomenon where we notice the contrast in the change of the drug levels in our bloodstream much more if the rate of entry of a drug is higher. Signup and view all the answers

The drug addict begins at a state of misery and withdrawal. If the drug addict takes a drug of abuse that has a fast onset, the association between drug and feeling better becomes stronger. Signup and view all the answers

Study Notes

Addictiveness of a Drug

The four features that determine the addictiveness of a drug are:
- Dose: the amount of the drug taken
- Route of administration: how the drug is taken (e.g. oral, injection, smoking)
- Speed of onset: how quickly the drug takes effect
- Reinforcement: the rewarding or pleasurable effects of the drug

Rate of Onset

A faster rate of onset is more addicting because it enhances the drug's rewarding effects, making it more likely to be abused

Contrast Phenomenon

The contrast phenomenon refers to the process by which a pleasurable sensation is experienced as more intense when it is preceded by a painful or uncomfortable state
The contrast phenomenon relates to the formation of addictive behavior by enhancing the rewarding effects of a drug, making it more likely to be abused
It is a key factor in the development of addiction, as it increases the likelihood of repeated drug use
