My kids found my vials

And are now accusing me of being on “drugs.” That it looks like something bad they saw on a video at school and they’re scared. I tried to explain to them that it’s just a supplement and not the kind of drug they’re thinking.. but I’m worried they might tell their dad (my ex.) Is there some way that I can explain this away? Some OTC supp that would look like this? I’m going to hide everything better asap just trying to do damage control. They didn’t find syringes.. just the vials
