Ah - you mentioned "chain of production" so I assumed you were only referring to the production of the drug, not its trafficking.
When you include trafficking you're right - but I did mention examples in my post that don't involve any exploitation, such as pharmaceutical diversion and people who grow and supply their own drugs.
