Cannabis uses a similar amount of water per acre as other agricultural crops in California: Researchers

The University of California Berkley Cannabis Research Center has been studying water use on cannabis farms since 2017.

The work has relied mostly on water use reports from farmers enrolled in California’s cannabis cultivation program, as well as anonymous farmer surveys.

And while the data surrounding cannabis use, especially on nonpermitted grows, remains limited, the Cannabis Research Center is beginning to form a better understanding of how outdoor cultivation impacts local environments.
