At Today You Can, the belief is that there is no permanent cure for addiction. Drug addiction is a complex disease, and quitting usually takes more than good intentions or a strong will. Drugs change the brain in ways that make quitting hard, even for those who want to. Fortunately, researchers know more than ever about how drugs affect the brain and have found treatments that can help people recover from drug addiction and lead productive lives. We do recover, however, alcoholics and addicts need to remain vigilant because they are only one slip from returning to active addiction.
I hope this helped you understand if there is a cure for addiction.
