When is tolerance adaptation?
Direct Answer
Tolerance is a physiological process where repeated exposure to a substance leads to a decreased response. This means that a higher dose is required to achieve the initial effect. Tolerance does not automatically mean that an individual has an addiction or a Substance Use Disorder.
Common Misunderstandings
["People often believe tolerance means drug dependence. Tolerance is a biological response; dependence involves withdrawal symptoms upon cessation.","A common misunderstanding is that tolerance always indicates problematic use. Tolerance can develop even with prescribed medications used as directed.","Some people assume developing tolerance requires active drug-seeking behavior. Tolerance can occur without changes in behavior related to obtaining or using a substance."]
In Practice
Tolerance indicates that the body has adjusted its response to a specific substance. For example, a person might initially feel strong effects from a certain dose of a medication. Over time, the same dose might produce a weaker effect. This necessitates an increased dose to achieve the original effect or impact.
What This Does NOT Mean
["This does not mean that tolerance is always a sign of addiction. Addiction involves compulsive substance seeking and use despite harmful consequences, a different concept from physiological tolerance.","This does not mean that developing tolerance guarantees future dependence. Dependence is characterized by withdrawal symptoms that appear when substance use is reduced or stopped.","This does not include behavioral adaptation to substance effects, such as learning to compensate for impairment. Tolerance specifically refers to the physiological changes decreasing the substance's effect."]
