Grandmother got influenced by juice

I learned about what percys are thanks to Juice WRLD and coincidentally found a bunch of pills in my grandmas cupboard and I identified them to be drugs juice talks about in his songs. I’m confused tho, because I never introduced my grandmother to juice WRLD, so how does she know to take the pills? Maybe I’ve shown her a song or two and I don’t remember, or just told her and didn’t pay attention. But still, how do I go out of my way to help my grandmother? She shouldn’t be doing stuff like this because of outside influence, it’s not really as cool as the thinks it is.
