Answer 1

Psychological factors such as a person's expectations, mental health, and level of tolerance due to substance use disorders significantly influence the effects of drugs, altering their impact on mood, behavior, and physiology.

Step-by-step explanation:

Psychological factors significantly influence the effects of drugs on an individual. These factors include a person's expectations, mental health status, and whether they have a substance use disorder. When a person has a pre-existing belief about how a drug will affect them, this expectation can shape their actual experience with the drug.

For instance, if someone anticipates that a medication will relieve their pain effectively, they may experience a heightened pain relief due to the placebo effect. On the other hand, those with mental health issues may react differently to drugs compared to individuals without such issues because their brain chemistry can alter the drug's intended effects. Moreover, habitual drug users may develop a tolerance, requiring higher doses to achieve the same effects, which can lead to increased risk of overdose and death.
