How to support/encourage my 15 year old daughter while her friends are starting to drink and do drugs. She’s just not into it.

I have noticed over the past few months her friends haven’t been coming around our house. It was also a regular thing that I would pick up her friends and take them to Starbucks (or wherever for coffee/dessert) and that hasn’t been happening much either. So I asked her what was going on and she said they have started drinking and/or smoking weed. At this time I don’t believe she has done either. So far she’s a really good kid, gets good grades in school, likes to stay home on the weekends etc. and I would like to keep it this way. Any ideas on how I can encourage her to not make the same choices her friends have?She has been hanging out with a new group of girls who seem to have the same mindset as her so I have of course been encouraging them and their goals (study/coffee dates etc) but I can’t solely rely on that.So any parents out there who have been there or have any ideas please let me know.
