Well exuse me, I didn't know i was talking to a renneissance man. Addicts wheel and deal with each other, rack up debts to eachother, steal from one another. Some of them buy wholesale from larger distributors, usually with credit, to be repaid with interest or else. They rob, assault, rape and kill eachother over this stuff. I wish i was making this up.

Doctors in emergency rooms usually have instructions to confiscate any illegal drugs they discover on OD-patients, but are faced with the very real dilemma of leaving the patient at their creditors mercy. This can cause real harm (as in "First do no harm") to the patient and their prospects of recovery or harm reduction.
