Substitution therapy works by introducing a safer alternative that can bind to the same receptors in the brain as the original toxic substance. This can help alleviate withdrawal symptoms and reduce cravings. For instance, in opioid addiction, medications like methadone and buprenorphine act on opioid receptors, providing relief from withdrawal while being less likely to cause euphoria or dangerous side effects. This allows individuals to maintain a more stable lifestyle and engage in additional therapeutic interventions such as counseling or behavioral therapy.
