Sure. Thanks for the question.
Something that would worry me is that what is provided will not be able to compete with the illicit market. The illicit market is often described as a "poison" drug supply. From the data available, it seems the market is supplying the demand of the end-consumer. When Paul Janssen invented fentanyl, one of the reasons was that it would have a fast onset and offset. For the end-user this means this drug does not have legs, meaning it does not provide the end-users with the duration of intoxication they seek. As a result, in B.C. roughly 50% of the drug supply has another type of drug in it, which is called benzodiazepine, that would provide the duration of intoxication. This makes the drugs provided more toxic. Because we have to think of safety, I'm skeptical that we can provide legal forms of drugs that the end-consumer will use to displace the illicit supply.
Going to your question, I think it will be difficult for the legal market to supplant the illicit market, because we have to think of safety. For instance, if someone overdoses and passes away, more people will actually go to that drug dealer to buy drugs from that person, because they have stronger stuff and that's what's sought after. Safety is not sought after as the primary end-goal of the end-consumer.
