I'm concerned legal cannabis with very high tax rates has created an ideal situation for criminal cartels. A criminal group can utilize legal businesses for growing expertise, cleaning money, etc. Meanwhile, the criminals may be more than happy to use extreme violence and forced labor to get their way.

I've seen things online about illegal grow operations in CA with a surprisingly bad impact on the environment since apparently the individuals managing these rural greenhouses don't care about litter or pollution, just like they probably don't care about their laborers. The law has given their mules protection to move products, and their customers a financial incentive to go with the risky illegal pot.
