Being addicted to drugs, also known as compulsive drug use even if the drug is not harmful. This problem is described by the inability to stop using a drug; the inability to cope with work, social or family commitments; and, at times, resistance and withdrawal. The latter reflect the physical dependence with which the body adapts to the drug, requiring more of it to achieve a specific impact (resistance) and evoking particular physical or mental indications of the drug if use of the drug is suddenly stopped (withdrawal). Physical dependence can occur with the constant use of numerous medications, including numerous doctor-prescribed medications, even when taken as prescribed. In this way, physical dependence in itself does not constitute a compulsion, but rather is regularly accompanied by habit. This improvement can be difficult to recognize, especially with prescription painkillers, for which the need to broaden measurements may indicate resilience or an increasing underlying problem, rather than the onset of misuse or fixation.
