Step-by-step explanation:
An assessment and treatment strategy that allows obtaining information about a person's substance-related problems and providing feedback to help increase his readiness for change is referred to as motivational interviewing. This approach is client-centered and aims to elicit behavior change by helping individuals to explore and resolve ambivalence. It is often used in the context of addiction and dependence, where it can facilitate a person's engagement with rehabilitation services.
Withdrawal symptoms associated with physical dependence on a psychoactive drug can include tremors, pain, seizures, or insomnia. In the case of heroin addiction, a person might be prescribed methadone, which is a psychoactive drug that reduces cravings and withdrawal symptoms without causing addiction itself, thus aiding in the treatment of heroin addiction and facilitating recovery.
