Withdrawal Support Programs

Methamphetamine Withdrawal Support

At 1142, we believe that every individual possesses the strength to overcome addiction. Our methamphetamine withdrawal support program integrates medical expertise, emotional support, and educational resources to guide individuals through withdrawal and empower them to build a foundation for lasting recovery.

Our approach considers the idea of replacing methamphetamine with alternative solutions to help individuals maintain their daily lives while working towards recovery.

This system was developed thanks to Cole Chenard, the original Biphentine man.
