Do you mean currently because of federal laws? Because if so, cool, that's currently the law of the land and you'd do well to abide federal laws if you want to keep your federal job.
Or are you strutting in here like Nixon making pot a schedule 1 drug because you're the ultimate paragon of morality and race relations, and that no controller could ever do their job while partaking on their weekends. Because if so, you're a jackass. Case in point: our friendly moose-banging counterparts to the north.
Thank you for your time.
