Definition
Drug consumption refers to the intake or use of a substance that alters the body's normal functioning. These substances can be legal (like alcohol or prescribed medications) or illegal (like cocaine or heroin).
This is a state where an individual relies on a drug for normal physiological function. The body adapts to the presence of the drug and withdrawal symptoms occur if usage is reduced abruptly.
This refers to a state where higher doses of a drug are required to achieve the same effect due to repeated use over time. It's like needing more coffee each morning to feel awake because your body has become used to its effects.
