Definitely not! You either end up replacing the drug addiction with a newly found alcohol addiction or you end up being addicted to both. I think the best thing for a drug addict is to find a well-balanced, healthy lifestyle. Since a lot of drug addicts already may have an affinity to being addicted to things in general, it may be important to seek therapy for addictions in general. A lot of the time drug addicts end up replacing their addictions with things that aren't even unhealthy to begin with, like working out or pushing themselves in their careers but making it an unhealthy addiction.

Conclusion is- it'd probably be best to stray away from alcohol if you're just getting rid of a drug addiction.
