Need help with Christmas present idea...?

I’m in a counseling class (we are trained to be peer counselors) in high school and our teacher decided she wanted to exchange gifts in the class via secret santa. I end up getting the most troubled kid in my counseling class (he smokes, he drinks, he steals, he does the hard drugs). I’m at a COMPLETE loss as to what to buy for him (I want him to genuinely like it). I dont want to just half-ass (for lack of better word) this gift. As for his interests, I know he likes basketball.. and spanish rap music… but that’s all. Any help?
