Nick, I have a couple friends that do the same thing, it started out with pot and now they do “just a couple lines” like once a week. Basically I have found that I can’t stop them…but I can pray for them that their eyes will be opened to the dangers of these drugs. I try to be a witness to my friends and remind them that what they are doing is wrong and could hurt them. I tell them, “What are you going to do someday when you have kids and they asked if you ever did drugs and you have to tell them that you were a pothead and snorted coke on weekends?” So far it’s falling on deaf ears, I think, cause they say, “I know” and do it anyway.
I hope our friends will grow out of this stage in their life. Pray, pray, pray, and good luck to you.
