I have a friend that is secretly using drugs(cocaine) I have suspected that she was doing it because of the people she hangs around with. Yesterday I stop over by her house on the way home from work, she already had company when I walked in the door one of her friends was doing lines, and quickly put it away, I didn't say anything. I just walked to the bathroom and debated if I wanted to stay there or leave or even if I should say something to her about. After being in the bathroom for 5 minutes , when I walked out she was doing it, and also tried to cover it up. I have known her for about 30 years, she is actually a big sister to one of my childhood friends, my question is jow or should I let her know what I saw, and let her know that I am not judging here for what she does. I still love her as I person , just not sure what to do. I do value her friends. What should I do?

Depending how hevy she is into it you have to be very careful how you say anything to her. If its something she's just starting on I would just bring it up slowly. If you have time try and be there with her wile the other frinds that do it are around. If she has you there and she knows that she can trust you she will be a little more open about it. But try not to be throwing her an intervention party any time soon cause that can throw her into a tail spin from hell in a heart beat. Coke works diffrently with a lot of people. I know from 4 years of the crap you have to be very tender footed about it.
