I doubt you'll see much overt support for your position in here Cetnik. IMO recreational drug-use of any sort is about the stupidest choice you can make at any time in your life, for whatever reason. It would be naive in the extreme to contend that there is no recreational drug-use amongst the pilot community -there's more than ample evidence that this is not the case. It is more than likely however that you'll find a majority of the pilot community are 'clean', are that way by choice and have been all their lives. As a function of that, you can expect to find an exceptionally low tolerance of self-confessed recreational drug users and an absolute intolerance of discovered 'closet' recreational drug users -for wont of a better way of putting it.
Do you stand a chance? Not in any organisation in which I hold a position of responsibility, if I know of your use.
