An unopened (non-controlled) prescription was offered for free in a Fb group I’m in. I sent a message to an admin recommending to double check that it was legal and was told there wasn’t an issue since it isn’t a controlled substance.

I am under the impression that is illegal even if the recipient has a prescription but I can’t find a specific law to point to. I am certain the offer is with the best of intentions, but I don’t want either the gifter/giftee to hurt someone unintentionally or get in unnecessary legal or the admin have the wrong info since more gifters will do the same after this. And as a person with many prescriptions I should know the law so I’m correctly informed.

I’m in Oregon, USA if that is helpful, as well.
Thanks much!
