In the context of drug abuse, what does 'overdose' refer to?

The concept of 'overdose' in the context of drug abuse specifically refers to consuming a quantity of a substance that exceeds the body's tolerance level. This can lead to harmful or even life-threatening effects because the body is unable to process or handle the excessive amount. An overdose can occur with both illicit drugs and prescription medications, and the consequences can vary depending on the substance used, the amount taken, and the individual's unique physiology.

Understanding the body's tolerance is crucial; it is built through repeated exposure to a substance, and individuals may mistakenly believe they can handle more than they actually can, especially after periods of abstinence. Recognizing the signs of overdose is essential for preventing severe health outcomes, making it a critical topic in discussions about drug abuse and harm reduction.
