How Long Does Liquid Methadone Stay In Your Urine – Methadone works by preventing opioid withdrawal symptoms and providing some pain relief. However, the effects wearing off does not mean that the drug is anywhere near having left the body.

Sometimes individuals in treatment have to try different therapies or even go through multiple attempts to find what works for them. Ultimately, the goal is a better life free from drugs.
