Please don't go there. I have 2 brothers who use and they will never be the same again. They started being late to work. A big side effect is that you would doze off. Car accident can occur. Shit, even one of them was sited for driving on the sidewalk while working. Trust me, coming from a person who's been there, done that, and forced to go sober, you don't wanna take that step. You might get promoted faster but you'll lose a whole lot more. As for me, thank god for probation officers. I've been clean since 2003.
