Believe it or not, in the long run and proverbial 'overall scheme of things', having it on your medical record that you are an addict is not such a bad thing as you are imagining it to be. As a matter of fact, it can end up helping to save your ass, especially in the longer term.
And if you don't get yourself quit, truth is, eventually you're gonna end up with a much more public 'record' of your drug addiction ... if you catch my drift.
