Activated charcoal affect nexplanon?

Pretty much what the title says. I know activated charcoal can mess with the pill form of birth control, but there’s nothing on the implant. I’m thinking it would be fine since the implant is already putting the hormones in my bloodstream, but I just want to check.

I have some tablets I opened up and put the powder into a bowl and left it on my counter. I used to use it to whiten my teeth. I haven’t used it recently, and I definitely didn’t ingest any. I don’t think possibly breathing it or being around it would do anything, right?
