Answer :

Final answer:

Psychological dependence and tolerance can lead to increased drug usage and withdrawal symptoms.


Explanation:

Psychological dependence occurs when a person has an emotional need for a drug, believing they can't function without it, even if there are no severe physical effects upon withdrawal. Tolerance is when more of the drug is needed to achieve the same effect, leading to increased dosage. Withdrawal can involve physical symptoms upon stopping drug use.
