Drug dealing is commerce that happens to be illegal. It's completely logical that most of the considerations of an ordinary market apply here. Drugs are a "victimless crime" in the technical sense that if all goes as planned, none of the people involved would have any complaint afterwards.
The thing is, the article doesn't mention the market for less victim-less crimes. It seems like a market for "murder for hire" would be a bit less reliable than a market for drugs - which is a relatively good thing.
Even more, those aiming to illegalize drugs inherently are aiming to make markets not function for drugs - aiming to make the experience more dangerous and costly than it would be otherwise. The most hardcore drug-warriors are open on this question but others try to sugarcoat it.
