DS, 17, has just gone away for a week. On the side in his bedroom he has left a plastic bag with the remains of some drugs in it. It's probably a 'legal' high. A parcel arrived for him recently so he clearly bought it online. We have a five year old so I'm also furious, in addition to any damage he may be doing to himself, that he would leave something like that lying around.
He is back next week so we have plenty of time to set out our reaction.
I would really appreciate any insights or experiences.
