It helps keep you busy
Exercise is a time consuming activity. That’s the good news. Even better, it keeps you busy and keeps your mind off of the drugs you might be craving.
You will also keep the thought of living a drug-free life at the forefront. You’ll feel like you can do just about anything. Busy is a lot better than bored, which is the usual mood when someone wants to try drugs (be it the first time or regularly).
You’d be hard pressed to find another activity that will keep you busy during treatment quite like exercise.
