Physical dependence is marked by a state of mental and physical abnormality when the drug is withdrawn.
The answer is True. A drug has different stages in its lifespan in the body. They include Absorption, Distribution, Metabolism, and Excretion. The route of the drug that affects its absorption includes oral, topical, intravenous, and etcetera. Type of drugs also affects absorption because, for example, strongly ionized drugs cannot easily cross membranes. Absorption for topical drugs on obese people is also reduced compared to normal weight people.
