Cannabis rarely the top water user in Northern California watersheds, UC Berkeley study finds

Cannabis cultivation is a fraction of the water demand in northern California’s rural watersheds, far less than residential users or non-cannabis agriculture. A peer-reviewed study published April 22 in PLOS Water.

The study, led by Christopher Dillis of the University of California, Berkeley, along with Ethan Baruch of the California Department of Fish and Wildlife and Theodore E. Grantham of UC Berkeley, analyzed 14 watersheds in 10 northern California counties, comparing water demand and flow impacts for three user types: cannabis cultivation, residential use, and non-cannabis agriculture.

Cannabis was the main water user in 1.6% of the sampling months. Residential use held this position in 34.6% of observations, and non-cannabis agriculture in 29.8%. Average annual water demand figures illustrate the gap: cannabis accounted for 1,665 cubic meters per catchment each year, 80,518 for residential use and 901,482 for non-cannabis agriculture.

According to the study, “residential and non-cannabis agriculture had the potential to impair streamflow on annual timescales, and the impact of cannabis water use was only evident on a monthly scale.” On an annual basis, cannabis did not produce any detectable streamflow without severity. On a monthly scale, impairments of 5% to 10% appeared, concentrated in small catchments of less than 20 upstream catches.

The image changes when all users exit the same shrink pool. The frequency of 1% impairment for cannabis nearly tripled, from 2.3% of months to 6.5%, when demand from the other two user types was already taken into account. The authors posit this dynamic carefully: “cannabis is much more likely to exacerbate existing impairments than to cause significant impairments in currents on its own.”

Drought increases this dynamic faster for cannabis than for other sectors. Because residential and non-cannabis agricultural demand is already high enough to drive the most vulnerable catch to spoil even in wet years, cannabis retains more potential to push additional catches above spoilage thresholds as conditions dry out. The authors also point out that water demand for cannabis has greater year-to-year variability than non-cannabis agriculture, and that unlicensed farms in particular “are more likely to move across the landscape each year than other water users,” making it difficult to predict where impacts occur.

The study recommends watershed management that treats all users together rather than separating cannabis, and points to small-scale off-site storage as a practical tool to offset dry season diversions. Licensed farms are already prohibited from diversion during the dry season; the authors note that reaching unlicensed operators will require direct outreach, and in a separate survey many of these farmers noted that they are “concerned about the environmental consequences of their practices.”

We don’t really deal with a lot of mites because of our IPM program

Flora Farms Pest Management Program it is built to reduce to nothing depending on the harvestso the plant ends up clean. Luke Allenbrand, Flora Farms’ crop leader, leads an integrated pest management program that focuses on prevention. “We don’t honestly deal with a lot of mites because of the IPM program, because of the predatory mites that we’ve put down as a precaution,” says Luke. “It allows us to have a much cleaner garden in the back half.” Preventative work keeps spray volumes relatively low because the curative side of the program rarely needs to be heavy.

“Actually, we are at the lowest number of these sprays that we have. The milliliters that we are using are numbers that do not exist to be a prevention,” says Luke. “But as soon as you see an uptick of those mites or anything, we bring it up to a therapeutic amount, which is still a small milliliter. And as long as you’re on a fast track with it, you see them disappear within 10 days.” The targets are spider mites, which feed on the plant’s THC and terpene production and degrade the flower.

Tested solutions
The three products used by the company are derived from agricultural and food use. “We actually apply about three insecticides that are very common around the agricultural and food grade of these products, using a suite of IPM, Venerate and Grandevo, insecticides that will deal with these mites,” says Luke. The application is intermittent rather than constant. “We usually use a 5-day spray cycle so we can have rest periods in between, so it’s not just a consistent density of that spray,” says Luke. He sees progress against mites in the gaps between the successions.

However, at some point, the spraying stops. “We finish the spray cycle by day 40. We usually don’t want to spray anywhere after day 40. At that point, you’re going to damage the product,” says Luke. “And at that point, we’ll put predatory mites in. It really helps us get to that final push point by day 59, 60 of that harvest. So we actually have a lot less of our spray in that late period. So it’s a much better tasting product.” Predatory mites take over the job of spraying, leaving nothing on the flower.

Biological control
Biological control has two forms. “We usually use them, they’re called crazy mites, and honestly, it’s crazy to see,” says Luke. “Actually, I’ve seen some of the ones in a close-up photo kill a bug, some of the cocoons actually drive away, and even attack the spider mites themselves. Very beneficial. Callias are also slow. They’re little bags that we hang on plants and they’re very beneficial to us.” Different predators work at different speeds, which is why the program runs more than one.

Missouri’s testing regime is the context in which growers operate. Each plant is tested for pest control chemicals and must pass before the product goes ahead. “Other crops and other black market shops or smoke shops in Missouri don’t have to worry about the testing we have to do,” Luke says. “Everything we use here is natural. Each of our pest management is a lot of essential oils that fight these mites. Everything we would put on a plant is food grade.” The test covers foreign chemicals, heavy metals, and anything else that an unregulated supply should never consider.

The whole arc is from biology to chemistry and back to biology. “We go from predatory mites to a food-grade spray regimen, and then back to predatory mites at the end. That way, these plants will have time to finish with no chemicals, nothing,” says Luke. “The rest of that life cycle, about 15 to 20 days, is the most natural it will have. No spraying at all during that, just to push predatory mites off that end, so there’s no residual mite damage on those plants.”

California Bill To Legalize Marijuana Dispensary Drive-Thru Windows Advances In Senate After Clearing Full Assembly

Published

It has been passed by a California Senate committee and passed by the Assembly bill that would allow marijuana dealers to offer car windows to serve customers.

The measure, which cleared the Senate Business, Careers and Economic Development Committee on a 7-3 vote Monday, says licensed cannabis retailers and micro-businesses with storefronts can sell marijuana products “in a motor vehicle to a customer in a drive-through located on the premises.”

Under Assemblywoman Gail Peller’s (D) AB 2697, cannabis businesses would need permission from the local jurisdictions in which they operate to add a drive-thru.

The sponsor told committee members before the final vote that the bill will “expand access to legal cannabis products while strengthening our ability to compete with the illegal market.”

Annie Aubrey of Chuck’s Wellness Center, a retailer in Placerville, testified that the legislation is “about improving access.”

“A large portion of our customers use cannabis as medicine, including seniors, veterans and people living with chronic conditions that affect mobility, the population that this regulated system seeks to serve,” he said. “For many, even simple tasks like getting out of a vehicle or navigating a retail space can be physically difficult or prohibitive…A drive-thru option removes that barrier, giving patients and consumers access to what they need in a way that’s dignified and consistent with their healthcare needs.”

Amy O’Gorman Jenkins of the California Cannabis Operators Association said the legislation will provide “operational flexibility” in a highly regulated system.

“It doesn’t expand who can access cannabis,” he said. “It allows retailers, with local approval, to serve existing patients and customers more efficiently.”

Jenkins also argued that this measure could improve security.

“Currently, road traction transactions are already allowed. This means that workers regularly have to leave a safe premises while transporting the product, and sometimes they have to deposit cash in parking lots,” he said. “AB 2697 provides an additional mechanism for obtaining product, but requires a fixed and secure transaction point, keeping employees inside and reducing exposure to theft.”

Pellerin, the bill’s sponsor, previously said that “California cannabis retailers lack a common and accessible transaction channel for consumers that so many other retailers in California offer, including fast food, pharmacies, banks and even liquor stores.”

“Cannabis consumers with mobility issues or other disabilities have limited options for obtaining cannabis without having to get out of their vehicles. And while home delivery is legal, there are restrictions on service areas,” he said. “Allowing cannabis sellers to add a secure ride option, if allowed by their local jurisdiction, will improve the consumer experience, increase the security of cannabis sellers and help expand California’s legal cannabis market.”

The California Association of Narcotics Officers opposes the proposal, however, as a representative, Ryan Sherman, testified that it would make it more difficult for dispensary workers to check the IDs of customers who are of legal age or to spot signs of current intoxication at drive-thru windows.

“This bill prioritizes speed of sale over public safety while undermining existing protections designed to prevent illegal sales and protect public safety,” he argued.

Under current policy during the COVID pandemic, dispensaries can already offer street pickup.

The invoice that moving forward in the legislature would mandate that auto sales “be made through a fixed panel security window with a security drawer or similar secure transfer mechanism that is part of a building located within the premises.”

California regulators recently approved emergency rule changes to the state’s marijuana licensing process. to make it easier for companies to receive benefits In line with the Trump administration’s latest move to federally regulate medical cannabis.

While Gov. Gavin Newsom (D) recently He took credit for helping lead the state’s push to legalize marijuana and discussed his limited experience with cannabis use.

In October, however, Newsom vetoed a bill that would have It allowed micro-marijuana companies to ship medicinal cannabis directly to patients Through common carriers like FedEx and UPS, he said the proposal would be “too burdensome and complex to manage.”

Newsom signed a bill earlier this month streamlining research into marijuana and psychedelics.

In September, the governor also signed a measure pause on the recent tax increase on marijuana products.

Separately, the state attorney general says Indian tribes cannot independently participate in the marijuana trade with licensed cannabis businesses without obtaining their own commercial license from state officials.

California officials have recently been rewarded nearly $30 million in grants for marijuana-focused academic research projects.
