I think if you have ever been addicted to anything you have to be vigilant and honest. With yourself. Only you know deep down if it's a potential danger.
For instance I know that me taking sedatives is purely my brain substituting - they don't knock me out, they don't alter me to the extent alcohol did and they certainly don't numb me. But it's me still bring able to pacify my beast with a token gesture. For now.
I know it's probably wrong. Deep down. It's not good thinking.
