6 Questions
Which of the following is NOT one of the variables that determine the addictiveness of a drug?
Rate of clearance from the body
Why is a faster rate of onset more addicting?
Because it causes a stronger association between drug and feeling better
What does the contrast phenomenon refer to?
The contrast in the change of the drug levels in our bloodstream
What are the four features that determine the addictiveness of a drug?
LEVEL of reward system stimulation, EXTENT to which the drug STIMULATES the reward system, RATE of entry into the bloodstream, Peak blood concentration of 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.
How does the contrast phenomenon relate to the formation of addictive behavior?
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.
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
