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: -A condition that occurs when the body gets used to a medicine so that either more medicine is needed or different medicine is needed.

Detailed explanation-3: -Tolerance typically is divided into three functional categories (acute, rapid, and chronic), but determining precisely which molecular underpinning underlies which class of tolerance (or if they are exclusive) can be difficult.

Detailed explanation-4: -Following repeated exposure, the effects of a drug can either be unchanged, lessened, or increased. When a drug’s effects are diminished following exposure to it, the change is called tolerance, when they are enhanced the change is called sensitization.

Detailed explanation-5: -Tolerance is a decrease in response to a drug that is used repeatedly. Resistance is development of the ability to withstand the previously destructive effect of a drug by microorganisms or tumor cells. Examples of drugs that result in tolerance include alcohol and opioids.
