It’s no secret that the United States’ $13 billion cannabis industry is big business. Less obvious to many is the environmental toll this booming business is taking, in the form of greenhouse gas emissions from commercial, mostly indoor production.

A new study by Colorado State University researchers provides the most detailed accounting to date of the industry’s carbon footprint, a sum around which there is only limited understanding. What is clear, though, is that consumer demand for cannabis is insatiable and shows no signs of stopping as more states sign on to legalization.

The study, published in Nature Sustainability, was led by graduate student Hailey Summers, whose advisor, Jason Quinn, is an associate professor in the Department of Mechanical Engineering. Summers, Quinn and Evan Sproul, a research scientist in mechanical engineering, performed a life-cycle assessment of indoor cannabis operations across the U.S., analyzing the energy and materials required to grow the product, and tallying corresponding greenhouse gas emissions.

They found that greenhouse gas emissions from cannabis production are largely attributed to electricity production and natural gas consumption from indoor environmental controls, high-intensity grow lights, and supplies of carbon dioxide for accelerated plant growth.

“We knew the emissions were going to be large, but because they hadn’t been fully quantified previously, we identified this as a big research opportunity space,” Summers said. “We just wanted to run with it.”

The CSU group’s efforts update previous work by Lawrence Berkeley National Laboratory researchers, which quantified small-scale grow operations in California and predated the cascade of state-by-state legalization since Colorado was first to legalize in 2012. To date, 36 states have legalized medical use of cannabis, and 15 have legalized recreational use.

Discounting transportation, which is common the both, the nett CO2 production of Cannabis is high due to the electricity use and the CO2 forcing.

It isn’t a given that indoor farming uses more energy.

Indoor vertical farms can produce high quality and virus-free products that can be locally distributed, inside the urban environment that such investments take place, saving annually millions of tons CO2 emissions.

Lighting is the big energy use that indoor farming has and that outdoor farming doesn’t need. On the other hand, I would say that outdoor farming uses much more energy for everything else.

There is the question of what we actually need.

Suppose that Joe needs a pacemaker. The infrastructure that enables the technology to build and implant the pacemaker also enables the creation of frivolous products.

You could argue that we don’t need 9/10 of the products we consume. However, if we didn’t provide a market for those products, that would eliminate the market for most of the stuff needed to make Joe’s pacemaker. Could the technology for Joe’s pacemaker be sustained just on the market for pacemakers? Probably not.

In other words, when you eliminate luxuries you also eliminate necessities. The Marxists don’t understand that.

My favorite example was shutting down freeway rest stops and especially restaurants at truck stops as non-essential, at the same time they were calling truckers essential workers and relaxing their required rest rules.

Economies are so intertwined that you cannot pick certain segments as non-essential. What if Joe Trucker likes to unwind by watching billionaires pay big millionaires to run into each other, or by keeping up with the Kardashians?

LoL! These grow lights are not 5W bulbs that you screw into a socket. These are high output full spectrum lights up to 600W and they are on 17-20 hours per day -multi million dollar operations where the biggest expense is the lights.

I grow microgreens indoors, which only use 20W T5 LEDs and even my setup pulls about $70-$80 per month electricity at $0.08 per kWh.

Right now indoor farming only makes sense cost wise for microgreens (which have low PAR requirements due to being harvested young) and tomatoes (because they are so efficient) – as far as food goes. For cannabis it only makes sense cost wise because it’s a ridiculously high priced crop under regulations/black market – it is still incredibly energy intensive. Its true value without regulations/black market would make it far more efficient cost wise to grow outside.

Utah State has hydroponic growing videos on Youtube with excellent info for indoor farmers/growers.

Hydroponic growing requires constant attention to the watering lines, salt contents and unfriendly flora and fauna.

Plants require constant maintenance and inspections. Not just one person wandering an easy to see field under bright sunlight.

Volatiles and aromatics coat the light sources and need periodic cleaning.

Harvesting is entirely by hand, with someone bending down to cut the stem below the branches.

Transporting to the drying rooms is entirely by hand, with someone carrying the plants to drying racks.

Drying rooms/sheds must be well ventilated to prevent molds and loss of plant quality.

Final dried product must be sorted, separated and packaged by hand.

Outdoor farming allows fields of marijuana to be easily tilled, sown and grown without extra water on less than arid land.
Harvested by combine with the stalks separated for fibers. The rest can be fed to ungulates without harm or intoxication.
All it takes is a few gallons of fossil fuels.

And you’re trying to claim that indoor farming is more efficient and uses less power than farming outdoors?
Marijuana is trouble free, has few insect predators and is easily grown and harvested in bulk.

If pretentious harvest for elite products is warranted, just as most hand harvested crops today, workers workers fill baskets that are picked up and transported mechanically.

Fussy handlers seek specialist products raised indoor, because:
A) Crop can be kept hidden, forcing police to use infrared optics to seek high power lamps.
B) Crop can be kept safe from two legged predators.
C) Indoor horticulture requires extra effort to control/exterminate aphids, scale, spider mites, whitefly, fungi, loss of air quality from poor ventilation and failure to exhaust stale expended gases.

The federal government is not enforcing the marijuana laws. They tried for a while, but there was so much controversy over it that they stopped doing it. Since that time numerous States have legallized marijuana to one degree or another, so the Feds have even less incentive to enforce the laws now.

Now that the Democrats have control of both Houses of Congress, they may just legalize marijuana nationally. They will throw it into one of their upcoming pork barrel spending bills.

The main problem marijuana sellers have had in the past is since marijuana is against federal law, no bank in the country would give the sellers a bank account, so the sellers were having to haul around large amounts of cash. Not a good idea.

I think the federal government finally passed a law shielding banks from jeopardy which will fix this situation. I don’t know if that actually took place, it was just being discussed some time ago and I lost track of it.

I noticed the other day that a large area of land next to a road a couple of miles away from here had been cleared of brush and they are putting in a large marijuana grow operation. It looks like they are going to use natural sunlight filtered through a translucent cover over the structures.

As if Joe’s election wasn’t bad enough, the insanity is now near perfect

people are using cannabis (and everything else that is called ‘drug’) to escape from 2 main things.

  1. Stress
  2. Loneliness

Stress mainly.
And where is the stress coming from if not endless tedious boring repetitive well-intentioned hypocritical virtue-signalling mendacious know-it-alls (sometimes laughably called: scientists) social-dysfunctionals who go under the banner of Politicians
and their legions and legions and legions of minions

Climate Change is The Stress Inducer of modern times.

But, they know they are doing all that: hence why alcohol is legal, also nicotine and now cannabis
If alcohol was a ‘new drug’ – it would never in a million years get approved for ‘food use’
Never.
It really is THE most hideous Brain Poison/Destroyer there could ever be.
Every doctor on this planet will tell you. They know, because most of them are perfectly addicted dipsomaniacs.
Medicine is a very stressful business

Our haha Leaders know that they are destroying (little) people with stress
They have learned, they instinctively know, that ‘drugs’ cause Dopamine release inside our heads and Dopamine acts as a ‘bandage’ to cover over the stress hormone Cortisol

Doesn’t fix or cure the stress, just covers it over for a while. Get that straight.
The Cortisol is still there and goes on to cause haha ‘Co-Morbidities
you may have heard of them recently

Hence, the little people are granted via huuuuge & epic munificence, some relief from all the stress that the politicos themselves, and know it, are causing.

Then what happens..
A bunch of perfect muppets, as we see here, patently didn’t get the memo and set about causing more stress about the very thing that was let loose to reduce the stress (of modern living, science and politics)

do you laugh or cry

Find out about Gabor Mate (pronounce Mattaye) and his book, available on audio also..
In The Realm Of The Hungry Ghosts

You will come to understand sooooo much about what’s going on in this world right now, you really will.
so much

Alcohol in beer improves the brain: Cliff Clavin’s Buffalo Beer Theory.

“Well ya see, Norm, it’s like this… A herd of buffalo can only move as fast as the slowest buffalo. And when the herd is hunted, it is the slowest and weakest ones at the back that are killed first. This natural selection is good for the herd as a whole, because the general speed and health of the whole group keeps improving by the regular killing of the weakest members.
“In much the same way, the human brain can only operate as fast as the slowest brain cells. Excessive intake of alcohol, as we know, kills brain cells. But naturally it attacks the slowest and weakest brain cells first.
In this way, regular consumption of beer eliminates the weaker brain cells, making the brain a faster and more efficient machine. That’s why you always feel smarter after a few beers.”

Proof positive alcohol is good for you. At least as much prof as CO2 is bad for the “climate”.

Perhaps you’ll be equally surprised to learn that cannabis plants also have to be hidden from sunlight for half of each day.
Since most strains of cannabis are “short day” plants, they will not flower if they do not experience 10 or more hours of darkness each night.
Crops grown outdoors in fields, as in Mexico, are marketed regardless of flowering and the leafy material of the bush is what consumers must content themselves with.
Cannabinoids are much more concentrated in flower clusters and that is the much higher value product of indoor operations, which discard the leafy material either to compost or solvent extraction.

Depends on the strain, most merely need placed in locations with partial shade. It ain’t rocket surgery or brain science, its weed. And I would put outdoor grown PA Home Choke up for the pepsi challenge. Some of these old boys been growing a LONG time.

If the cannabis growers inject CO2 into their greenhouses to accelerate the plant growth, the CO2 is consumed by the plant’s photosynthesis, so that would be a net CO2 sink.

But if they consume electricity for “high-intensity grow lights”, generating that electricity would emit CO2.

Why can’t the cannabis growers be “green” and rely on natural sunlight to power the growth of the cannabis plants? Isn’t solar power supposed to reduce emissions?

Of course, when the pot is eventually smoked, it will emit CO2 (as well as carbon monoxide and other toxic air pollutants).

Hey libs, stop getting high and cooking the planet and drowning Florida! What would Al Gore think of this?

Perhaps this fuel cell from Denmark will solve energy and carbon emission issues for pot growers. Install a turbine to produce power to electrolyse hydrogen from water, then use the hydrogen in the fuel cell to power the the pot factory. High and dry, so to speak.

I guess we now know these researchers think reindeer fly high on a regular basis. Well caribou anyways. Or maybe it is the polar bears polluting the North Slope. Arctic fox?

Somehow, their choice of what to plot makes it look like one of the scarcest populations in the country is somehow out polluting California when it comes to growing your own pot indoors.

I say quit harassing the natives. If you lived where the longest night took days before sunrise. Same thing with longest day taking days before sunset. And you had four proper seasons, June, July, August and Winter. Wouldn’t you feel the need to spend a lot of energy to grow your own. You are already spending the energy to heat and light your home. So what if you sacrifice a little of your precious heated space and put in a growing lamp.

People living in Alaska, North of the Arctic circle are few and far between. The community once called Barrow only has 4000 or so people living in it. Everybody up there could grow their own and it wouldn’t show up as a blip in the GHG emissions. Yet on this map, they are some of the biggest GHG polluters in the country.

Just more co2 bashing.

Co2 is 0.04% of the atmosphere and it is impossible for a trace gas to impact the climate. The UN/IPCC has not produced experimental evidence quantifying co2 climate sensitivity.

It is even questionable the impact water vapour, which is far more prevalent than co2, has on the climate.

The experiment, organized by Mother Nature, already shows beyond doubt: there is no positive feedback of water in the atmosphere.

The words of wisdom say no alcohol, tobacco or caffeine. Nothing about pot. But moderation in everything.

The Word of Wisdom (1833) advised against the following: wine and strong drink, tobacco, and hot drinks. Wine and strong drink is now considered to cover all alcoholic drinks, and hot drinks were defined early on as tea and coffee (tea from the tea plant, not herbal teas). When other recreational drugs became prominent in the 20th century they were condemned as being against the spirit of the Word of Wisdom. Caffiene has been suspect for a long time because of its connection with tea and coffee and many LDS don’t use it; but it has never been explicitly prohibited and many LDS do use caffienated drinks. The latest official church statement on the Word of Wisdom (2019) says “avoid substances that impair judgment or are harmful or highly addictive, whether legal or illegal”. It goes on to specifically mention marijuana: “substances such as marijuana and opioids should be used only for medicinal purposes as prescribed by a competent physician.”

Long story short — recreational marijuana use is considered against the word of wisdom and has been for many decades. It’s unlikely any active LDS using marijuana recreationally are ignorant of that. But prescribed medical marijuana is explicitly allowed and the Word of Wisdom only addresses consumption, not production. Even if it had been prohbited, compliance with *any* commandment falls short of 100% in the LDS church (and any other church), so the existence of LDS pot-growers still would not be surprising.

Back to the regularly scheduled mocking about the giant carbon footprint that isn’t really a problem, let alone a crisis.

As an apostate from the High Church of Psychedelia, I am always saddened to see the success of the MKUltra program these many years later! The CIA spent years studying drugs, especially LSD, for human mind control; only to realize they didn’t need to force it on the population. They only had to introduce a few of the 1960s counterculture leaders to it and then sit back and watch as an ever increasing portion of the electorate voluntarily started damaging their own cognitive abilities with the drugs they took in their de facto religious rituals!
The push to legalize rather than decriminalize marijuana received a huge boost when the pols realized they could tax it heavily, and Big Tobacco decided it could become a replacement crop for them to profit from! Sadly, supporters of legalization have largely ignored or denied the studys from around the world showing the increase in violence and psychological damage caused by frequent use of the high strength cannabis that is all the modern rage!
Alex Berenson documents the downside rather succinctly in his book; “Tell Your Children,” so I won’t reiterate his conclusions; but it seems obvious that there is much to be gained by the PTB if the populace has a large minority that is easily persuaded and often lacks sound reasoning skills. You might end up with a senile, decrepit old man as your titular ruler; while a cabal of unaccountable radicals control his every action for the benefit of your number one geopolitical competitor! Nah! That could NEVER happen!

“The CIA spent years studying drugs, especially LSD, for human mind control; only to realize they didn’t need to force it on the population.”

They don’t need drugs, all they have to do to control the minds of people is to be able to repeat a lie often enough, with enough authority, that the lie becomes the “truth”.

The Leftwing Media gives the Elites the means to repeat lies over and over and over again. And that’s what the Leftwing Media does: High-tech brainwashing of the population.

The first step to break the grip of brainwashing is to realize you *are* being brainwashed.

Look at the state this brainwashing has put our nation in. We have put a traitor and a criminal in the Oval Office.

If the Leftwing Media had not censored, right before the election, the New York Post story about Hunter Biden’s selling of his father’s influence, Trump would have been reelected Depending on which poll you looked at, between 10 and 20 percent of those who voted for Biden said they would not have voted for him had they known about his son’s shady overseas dealings.

Joe’s looking shaky lately (mentally). Maybe that’s why Kamala is talking to heads of state instead of Biden.

Kamala is the one who told an obvious lie about Kwanza and herself, and she told this lie when she didn’t have to do so. Nobody cared about Kamala and Kwanza, but she apparently felt compelled to enhance her image by connecting herself to the celebration of Kwanza.

When a person lies when they don’t have to, there’s something wrong with them. They have a mental problem of some kind or another.

Not much to look forward to.

I don’t think green or any other concerns figure materially on the commercial growth of weed. In my “recreational” state, someone ran for city council on a platform of using vacant tear down lots in decaying residential area to raise marijuana. Besides the “green” attributes and to borrow a common phrase from addiction recovery, “If we keep on doing what we’re doing, we’ll keep on getting what we’re getting.”

It seems to me that agricultural processers of grain like ADM could make short work of competition in growing. ADM once had a giant hydroponic farm run on their excess heat and CO2 that they ran just for virtue signals back in the day. Does weed sell for more per pound than tomatoes?

Taxes? Could weed be the new alcohol, tobacco, firearms and gaming? I am sure that my complaints about the ill effects of cannabis use on public safety and society will be used to justify the taxes and while protecting the cash cow.

My son grew the 4 plants allowed by the Canadian gubmint in My greenhouse. Tech in spades – seeds ‘feminized’, different strains for THC and CBD. Apparently if there is any ‘wildtype’ male pot around it will fertilize the feminized plants and you get seed instead of bud. Harvesting took him several days picking individual buds and separating the leaves out. Even with one plant getting mould, my freezer now has enough for him for years to come.

I can’t believe with over 100 comments no one has commented on the carbon footprint map. California indoor grows must be using unicorn power and fairy dust for electricity, because last I checked they were the state that was importing the most electricity, and the state they are importing it from has a much higher carbon footprint according to the map. It even appears the closer you get to the Libtard Nexus of San Fran the lower the footprint is.

Iowa and Kansas, which are #1 and #2 in terms of wind energy production per capita, don’t seem to have any influence on the map. And Vermont, which generates almost all of their energy from hydroelectric, also has just as high as a carbon footprint as anywhere else outside the glorious utopia of CA. I’d certainly like to know the secret, probably has something to do with a piece of paper that claims that their indoor grows are only pulling “renewable” energy off the grid.

P.S. It makes me feel dumb just saying ‘carbon footprint’.

The denigration of a product of commercially significant, simply due to one aspect of the plant is disappointing. I am not a pot user, but have followed the research and acknowledge the damage of selected varieties with high THC levels, (SIC) Wiki- (THC), the principal psychoactive constituent. Some strains have been selectively bred to produce a maximum of THC(EQ)
But this has stimmed the commercial use in agricultural use, in many countries.
