drug tolerance and withdrawal symptoms
Drug tolerance refers to the body's decreasing response to a drug after repeated exposure. This means that a higher dose of the drug is needed to achieve the desired effect. Withdrawal symptoms occur when a person abruptly stops taking a drug that they have become dependent on. These symptoms occur as the body goes through the process of adjusting to the absence of the drug. Symptoms can vary but may include physical and psychological discomfort, such as cravings, anxiety, insomnia, and sometimes even more severe symptoms depending on the drug.
