Quizplus · Accepted Answer

Oral consumption is the least efficient method of drug administration because it must go through the digestive system and undergoes significant first-pass metabolism in the liver before reaching the bloodstream, leading to a lower bioavailability compared to other routes of administration. Injecting drugs directly into the bloodstream or brain bypasses these barriers and provide more immediate and efficient effects. Inhaling drugs also provides a faster onset of effects because they are absorbed through the lungs and directly into the bloodstream.
