AP PSYCHOLOGY

Detailed explanation-1: -A person may develop tolerance to a drug when the drug is used repeatedly. For instance, when morphine or alcohol is used for a long time, larger and larger doses must be taken to produce the same effect.

Detailed explanation-2: -With repeated use of drugs, the tolerance level of the receptors present in our body increases. Consequently the receptors respond only to higher doses of drugs or alcohol leading to greater intake and addiction.

Detailed explanation-3: -According to the current edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), tolerance has two aspects, a need for a markedly increased amount of a substance to achieve the desired effect and a diminished effect from the same amount of a substance.

Detailed explanation-4: -If your body has developed a tolerance to a medication you’re taking, it means the medication at your current dose has stopped working as effectively as it once did. It might mean your body becomes used to the medication, and you don’t get the same benefits or effects as before.
