Drug repercussions/Dodgy Body Parts

What would be the response if a drug dealer, on conviction, as part of their sentence, was ordered to become dependent on the drug they were selling, and then made to go ‘cold turkey’?  The higher up the ‘food chain’, the more times they go through the process.  Similarly, persons who partake in ‘dodgy’ body parts traffic should, on conviction, become candidates for experimentation of medical processes; especially using the parts they were selling.
