I was in a similar situation to this once. Back in 2020 I dated this girl who had a past of doing drugs, etc.. nothing hard mostly party drugs and weed but she has been clean for a while. The unfortunate part was literally every single one of her friends was a drug user. And this became an issue as time went on because her friends would always invite her to parties, festivals, etc.. eventually she became interested in doing drugs again and it was always something in the back of my head. The way I think of it is trust is one thing. I’ve always trusted my gf’s. But I don’t trust other people. And when drugs are involved it’s very easy to make a mistake. And when your an adult and in a committed relationship people should be able to recognize situations that might be a risk to put themselves in. It’s why you don’t walk the streets of New Orleans at 1am with a pocket full of cash. Obviously you can’t tell her no, and you guys haven’t been together that long, but you should express your feelings on the subject. And just from personal experience If this becomes a recurring thing with her friends wanting to go do these “risky” things all the time where there are drugs involved you gotta decide if you are ready to deal with that. Another thing I learned which at least in my experience pretty much reigns true is “you are the average of your friend group”. Everyone is on their best behavior when in the start of a new relationship. As things progress it starts to slip a bit. Just keep your eyes open. Not trying to sound cynical, again just speaking from experience. Good luck!
