Like the marijuana has to meet certain standards, and regulations, right?
So organic pesticide companies can make a killing selling these growers, organic pesticides. You could invest in the tech companies that provide the digital monitoring equipment they REQUIRE FOR EVERY PLANT, SEED, AND FINISHED PRODUCT.

You could invest in the security services they will need to keep the dispensaries safe. Or the equipment/company used to test the potency of the product. The energy companies providing power to all these indoor grows.

I mean just endless shit I feel...
