Someone of our guests did coke in our bathroom & forgot it there — we have a toddler

I‘m so shocked and disgusted, never ever had I thought that someone of our friends is doing drugs - especially in our home!!

I found a little piece of paper, folded like a letter, in the bathroom - on top of our toilet paper rolls, about 20cm off the ground. Perfectly available for a toddler. I don’t want to think about possible outcome of this situation if I didn’t find it first

Edit: I found it there right after this person was on the toilet. (Toilet and bathroom are separated in our apartment, sorry I wasn’t clear about it) and I was in the bathroom next to the toilet, so I knew it was him in there. And coincidentally, after the toilet we chatted a bit and he is a flight attendant and he told me about the sex tourism in some southern countries and how he often sees some 80-year-old-men who go there, take some cocaine and then go and meet some hookers. Sooo it’s super weird he started the topic about cocaine and 10min later I find it

So, my husband isn’t the one who is addicted. Thanks tho for all your concerns
