When you consider that most things are processed to be addictive in our food supply and such, and even to some extent research can be addictive. then you really need to think on that for your self as a whole.
To be honest, in my opinion, so long as you make an assertive and honest attempt to enlighten yourself then one should have no problem. I think it is of the mind as well as the body.
I mean when you stop and think that one is inhaling toxic fumes from filling your gas tank and taking in toxic air from cars and planes over head, what would it mean to not smoke or drink when you work at an airport or refinery..
Just something to ponder
