The likelihood of an addict to relapse depends on various factors, such as the severity of their addiction, the length of time they have been addicted, their support system, and their personal motivation to stay sober. According to the National Institute on Drug Abuse (NIDA), the relapse rate for addiction is estimated to be between 40% and 60%, which is similar to the relapse rates for other chronic diseases like hypertension, asthma, and type 1 diabetes. However, it’s important to note that relapse does not mean failure and can be part of the recovery process. It is also important to remember that addiction is a treatable disease, and with the right support and resources, people can achieve long-term recovery.
