Need Highschool social advice abt rumors!!

I’ll be changing names
So basically me and a couple of girls were talking in a group of 5 about drinking/weed. For context, 2 of the girls I’m on good terms with, one is my opp from 2 years ago I’ll name her Amaya(long story short I was uncomfortable with her smoking and started moving kinda weird), and one is my pretty good friend, Sabrina. And then the other girl is Casey, I’m on pretty neutral terms with.
The thing about Sabrina is that she can trash talk a lot of people, and I’m sure she has trash talked me before too. She’s pretty close to my opp Amaya, but has still trash talked her to me too. Overall not the most trustworthy person. It’s not like she hates us, she just thinks trash talking can be fun / sometimes launches into these rants like she’s some philosopher. But the key take away here is that we are still extremely close/she’s always making an effort to hangout, I’m just aware of her tendencies to talk about other people.
Back to what we were talking about. Amaya, Sabrina and Casey have all smoked weed before and done a plethora of stuff. Me on the other hand, all I have done really is drink. I do not plan on ever smoking, it just seems so pointless and harmful for ur health. In the moment however, I didn’t want to be excluded, because they were talking about all meeting up to smoke. So I asked them if I could buy weed from them, kinda as to soft launch the idea that I’m down to join in. They started saying they don’t wanna sell to first timers bc they’d feel guilty, and that I’d first need to start w smthin else(this wasn’t rlly abt making sure I wouldn’t be able to hangout, it was coming from a place of morals). At first I said it’s not like I’m gonna become an addict and I js wanna try one time, but I let it go quickly and said I totally understand.
Anyways, the part I’m worried about is that Sabrina and Amaya are going to end up trash talking me at school and students and even teachers may over hear. They got a couple classes together, so that’s ample time to fill with talking. I know sharing a class can help get people closer, and I didn’t get a single class with them. To be honest I really don’t know how much the situation meant to them. I know that Amaya might wanna trash talk me for the sudden switch up, seeing as 2 years ago I was acting like a goody two shoes about her smoking. On the other hand, she might not find it too important, seeing as she was talking about doing a bunch of stuff like acid/actual drugs, so may not think me wanting to try weed is that big of a revelation.
What I really need advice on is what should I do next; am I completley overthinking it right now, should I send a text, or what else? Thank you!!
