Welcome to SR, Squeeealer. I think you're on the right track, almost any gift would most likely be sold for drugs.
When my son was around (and active in his disease) I bought him things like socks and underwear or warm gloves (he lived on the street a lot) or I just took him out for a nice hot dinner.
For me it wasn't about deciding if he "deserved" it, it was a gift of love that could do no harm. We all deserve that, I think.
Hope you stay with us a while, and make yourself comfortable. You've come to a good place.
Hugs
