I've heard some recovering addicts claim that they can casually enjoy drugs they were addicted without ever worrying about compulsively using said drugs again. To them, they say, this is evidence that they are finally in control. IMHO, this doesn't prove anything because if you wanted to stop using drugs why should you look back and want to continue using the drugs again [now that you are in control]? Wouldn't this eventually end in addiction when you want to have just a little more? It doesn't really matter if you think you are strong enough to use a drug without getting hooked once again. It's not worth the risk because there's a high probability eventually your "defenses will be worn down" and you'll start using drugs like as you did in the past.
