"Just remember, its not a lie, if you believe it." (Seinfield)
I often see people who use weekend party drugs try to justify it to themselves and others by talking about it as if to decriminalize it:
'its just like drinking or smoking'
'sure, its illegal now, but its legal in other countries'
leading a hidden life is dangerous for a couple of reasons.
1) you will get caught or slip up and get caught in a lie, this will bring everything you have done, legitimate or not into question.
2) if something were to ever happen to you, and you couldn't help yourself to say, hospital. Calling Lance ( pulp fiction) isn't going to help.
If you are in the presence of others who hear you talking like this, your cover is blown. They could be your boss, friend-of-a-friend or just a colleague within earshot of you. Even if they don't say anything themselves, perhaps at risk of exposing their own demons; everything you say will be questioned. They will wonder what else you are hiding/lying about. If they gossip about your situation, it could snowball very quickly to a broken relationship or loss of employment. your reputation takes years to build and moments to destroy. My philosophy is if you can't get clean...come clean. Tell someone - Your Dealer does not count! An emergency contact/next of of Kin needs to know, They don't need to know everything, but they need to know something.
Having a secret life from EVERYONE is dangerous. having a secret life from everyone else is just a matter of privacy. but you need someone to keep you in check and that you can turn to if things ever do come to light.
I would not consider your right to privacy as leading a double life. I would highly recommend keeping your proclivities private, but as I said. Get someone you trust, to keep you in check and have some answers should anything go pear-shaped.
Don't confuse secrecy with privacy.
