You want to prevent diversion out of your legal, regulated regime into the illicit market. There are many aspects of preventing diversion from the regulated market to the illicit one. However, one of the best ways to do it is through seed-to-sale tracking. This is something that Canadians are familiar with. They're familiar with the language of “gate to plate”, for example, in relation to much of the food that we consume. Seed to sale is something that we saw in place in states like Washington and Colorado to prevent diversion into the illicit market. We saw it at work in the licensed producers we visited as a task force.
You can trace that seed through its growth to whatever form it ultimately appears in within the retail market. It is not only a health promotion and safety mechanism for understanding where the product came from and the quality controls used by the producer or manufacturer. It also helps law enforcement. For example, if that bar code is not there it should tell you, in a regulated system, that you're dealing with illicit product. Likewise, if you find product with a bar code being trafficked, it will tell you it has been diverted.
