While ACT is relatively new compared to traditional CBT or 12-step programs like Alcoholics Anonymous, ACT has shown great promise as an approach to helping those who struggle with drug and alcohol abuse. Studies from methadone-maintenance programs show that including ACT in therapeutic interventions reduced both opiate and other drug use. ACT has also been shown to be more effective than nicotine replacement therapy to quit smoking long-term. There is also evidence for ACT and recovery from alcohol addiction.
