Water in California is a notoriously hot commodity. As a state that’s spent more time in a drought than out of it during the past five years, legalizing a new, water-intensive agricultural crop—especially when that crop has the historical baggage that cannabis does—is a complicated process.
Done carelessly, cannabis grows can have profoundly negative impacts on nature, polluting waterways with pesticides and clearing trees and shrubs that help support a healthy ecosystem. This is especially true of illegal cultivation, which has bled into national forests and other protected land in recent years.

“We’ve got a [water] crisis on our hands in California, and it’s much bigger than cannabis,” Allen said.
The Stages of Cannabis Plant Growth
In an effort to balance environmental concerns with marijuana’s projected $7 billion market, California is ushering in a bevy of rules and regulations related to water use. In June, Gov. Jerry Brown signed a cannabis omnibus bill that, among other things, sets standards for organic marijuana and establishes environmental protections.

The bill, SB 94, includes a provision that allows regulators to restrict cannabis cultivation if they determine it’s causing environmental harm. Specifically, it bars the Department of Fish and Wildlife “from issuing new cannabis licenses or increasing the total number of plant identifiers within a watershed or area, if the board or the Department of Food and Agriculture finds, based on substantial
