Much like Big Tobacco, the billion-dollar commercial marijuana industry cares more about making a profit than protecting public health.

Cannabis promoters have been making use of their hefty advertising budgets to convince voters in five states — Arizona, California, Maine, Massachusetts, and Nevada — that legalizing recreational marijuana will not only be economically beneficial to the state but will also help save lives. The latter is a frightening and misleading claim. Here’s why.

Proponents argue that legalizing recreational marijuana reduces opioid abuse and overdose death. A recent article in STAT pointed to a 2015 white paper from the National Bureau of Economic Research suggesting that access to medical marijuana was associated with a 16 percent decrease in opioid overdose deaths and a 28 percent reduction in opioid abuse treatment admissions.


What the findings of that study don’t showcase are the increases in traffic fatalities, hospitalizations, and marijuana-related poisonings following the legalization of recreational marijuana. In Washington state, for example, the number of traffic deaths due to marijuana-impaired drivers doubled in the year after recreational marijuana was legalized. In Colorado, the number of fatal accidents involving marijuana rose by 62 percent since its recreational use was legalized in 2012.

Law enforcement officers can rely on Breathalyzer tests to identify drunk drivers. But there’s no equivalent for drugged drivers, making it difficult to deter or punish them.


In Colorado, marijuana-related hospitalizations have increased an average of 30 percent a year since legalization. Marijuana-related poisonings also rose sharply in both Colorado and Washington.

Just as secondhand tobacco smoke can harm individuals who don’t smoke, marijuana can also harm nonusers. If the new laws pass, they would authorize the promotion and sale of highly potent marijuana edibles, including candy, cookies, and soda. These account for nearly half of all marijuana sold in Colorado. Edible forms of marijuana pose a particular risk for kids and pets.

Advertisements for Pot Tarts, Hashees cups, and cannabis gummy bears will become as common as the soft drink promotions targeted at the youth market. No limits have been placed on the potency of edible products in Colorado, nor will such limits be written into the proposed laws in most of the states looking to legalize marijuana. Edible products have been known to have levels of THC, the active ingredient in marijuana, reaching as high as 95 percent, compared to 20 percent to 30 percent generally found in marijuana plants.

Writing in JAMA Pediatrics, doctors at Children’s Hospital in Denver reported that after recreational marijuana was legalized, its emergency department began treating one to two kids a month for accidental marijuana ingestion, mostly from edibles. Before legalization, the hospital hadn’t treated any kids for this.

Proponents of legalizing recreational marijuana use argue that it will save lives by giving people an alternative to opioids for pain relief. What they don’t consider is the detrimental impact of recreational marijuana on youths. When Colorado legalized marijuana, it became the number one state in the country for teen marijuana use, with teen rates jumping over 12 percent. In both Washington state and Colorado, the illegal black market for drugs has exploded, with organized crime groups growing large amounts of marijuana illegally in Colorado homes and shipping it across the US, increasing youth access to the drug.

While using marijuana by itself is unlikely to be life-threatening at any age, it can cause serious problems. Numerous studies have linked marijuana use to mental health problems including increased rates of anxiety, mood, and psychotic thought disorders. Marijuana use is also associated with relationship problems, poor academic performance, employment issues, and lower life satisfaction. With the increased potency of marijuana, these problems are even more significant for today’s users.

Marijuana use during adolescence is especially damaging in terms of impaired cognitive function, including memory issues, learning deficits, and lower IQs, all of which can persist into adulthood. Despite that, the majority of high school seniors don’t believe that regular marijuana smoking is harmful. In fact, only 36 percent believe regular use puts the user at great risk, compared to 52 percent five years ago. Nearly 1 in 15 high school seniors use marijuana on a daily basis, while 21 percent of all 12th-graders report using marijuana in the past month. Also, more young people seek treatment for marijuana abuse or dependence than for use of alcohol and all other drugs.

When states legalize recreational marijuana, fatalities increase and the lives of children and teenagers are put at stake.

  • The science of marijuana’s impact on brain development, cognitive function, learning deficits, lower IQ and memory (to name a few) is clear. Marijuana use, particularly during the brain’s most active development period (12-24), is harmful. However, as more states and countries are legalizing or considering legalizing marijuana, the overall perception of hard decreases while use rates increase. This is an interesting trend; more young people report using marijuana. A good idea is for the public to get a better handle on what is happening.

  • I have learned some significant things through your site post. One other point I would like to mention is that there are various games out there designed specifically for preschool age small children. They involve pattern recognition, colors, wildlife, and styles. These commonly focus on familiarization instead of memorization. This keeps little kids occupied without feeling like they are studying. Thanks

  • I’m not a fan of the societal problems I see from marijuana. I’m not a fan of criminalization either. We’ve been beating that dead horse for decades only to see the problem get worse. As the article says it may not kill you directly, but that doesn’t necessarily make it a good thing either. The medical industrial complex along with the CIA run black market drug trade is largely responsible for our opioid crisis. So let’s not conflate that with marijuana as a lesser evil solution to that problem. Both are bad from an overall societal perspective for different reasons. There’s lots of money to be made, and the people making it are not really any more responsible than the alcohol or tobacco industries. For people who like to say it’s not as bad as those you might want to take a look at those industries. That’s not exactly a ringing endorsement. I’m not entirely sure the traffic statistics paint an accurate picture either. If it’s like alcohol any amount in your system is counted as alcohol related. That doesn’t necessarily mean that’s what caused the accident. However, it’s hard to come up with a definitive means of measuring just what the true impact is. 62% is huge and you can’t just dismiss that all of that increase as due to those edge cases. I think the solution is education. Much like with alcohol, smoking, and other drugs we need to have hard and honest conversations about the real impacts of these things. The politicians never met a source of income they didn’t like. They won’t give up the tax revenue regardless of what the social impact is. So we need to be prepared. Legalization is coming for better or for worse.

  • So many questions… It is addictive, it is smoking/hence affects lungs, etc., it impairs / alters the mind……. It is worst than cigarettes. People rent the property, cut holes in the garages, and ceilings, destroy the house, CONTAMINATE the house, it causes MOLD.. So, it is robbing the Landlords of their clean property and costing them a fortune, and it is causing a health HAZARD to everyone. Legalizing Marijuana robs us of our Constitutional Rights. It is shoved down our throats……. Greed has prevailed, just as it did when someone glamorized smoking… Who drives under the influence of Marijuana? Is your Babysitter using? Is the Caregiver in charge of your Mom, or Grandmother, using? Have we gone totally foolish? HOW is legalizing a TOXIC mind altering product, logical? SHAME on those who are promoting this mess. We have a huge house and everyone who rents it… wants it to grow Marijuana. We are constantly having to redo this house over and over…… Where are our Rights protected? The Sheriff comes and says to leave them alone, because it is LEGAL, yet, the Lease, a Legal and Binding Contract PRECLUDES cultivating. It is sheer insanity. You should post our pictures of the damages… on the News… ALL those Tenants sell the marijuana. The Pizza fellow was seen delivering 2 Pizzas and a huge Ziplock bag of Marijuana.
    Greed………….. Do we need 10-20 years to pass before we realize that this is WRONG? I want the insanity stopped before it kills more people.

  • I see a lot of angry comments directed toward the author. While I am in complete agreement with the decriminalization of marijuana I am seeing some elements of this new wave of commercialization of recreational marijuana as not such a good thing. The comparison to Big Tobaco is absolutely correct. It is, in fact, all about money when you are in the recreational marijuana business and reaching as many customers as possible. There are huge advertisements and billboards all over L.A. county now promoting the use of marijuana and marketing it in such a way that it is “cool”, “hip” and even, get this, “healthy” That is complete bullshit. The CEO of MedMan here in Los Angeles California is even quoted as saying this on his website, ““Marijuana today is less about smoking a joint, and much more about lifestyle and culture. It is about healthier, safer choices for mind and body, and community.” “Healthier choices”????!!! Really? How in the world is sucking smoke into your lungs a healthy choice??? How is altering your mind chemistry for the sake of getting stoned healthy? It isn’t. This is just an example of the corporate leaders in the industry doing and saying anything to market the drug in a new way and to enlist as many people as possible into buying their product, just like Big Tobaco.

    I am not against people smoking weed. I smoke weed. I have smoked weed for a long time but I am not proud of it and I see a dangerous precedent being set by the flood gates being opened to corporate greed capitalizing on a drug.

  • It’s real easy to come up up with a BS arguement for why it could be bad. That’s why it’s taken so long to get it legalized. Now everyone sees right through people like you. Do you leave your coffee grounds laying around on the counter, or leave your regular brownies out for your kid or dog to eat? How about all the kids who end up deformed because of parents ingestion of opioids? Get a life and some new false information. I’d love to hear it.

  • Wow!!!!
    Please Stop Spewing So Much False Information about Marijuana!!
    It’s Killing People??? REALLY???
    We certainly wouldn’t want anybody’s dog to accidentally get high either.
    Maybe you should go Blow Sessions & Trump- Dumb Ass

  • Hi Candice – I am GLAD to hear you were tested for celiac disease and found negative. I wouldn’t wish it on anyone. Now …Since I am always wary of answers doctors give I find myself doing research when I think there may be a reason for it. Crohn’s, according to your doctor, can’t possibly cause pancreatitis yet this article “Pancreatitis in inflammatory bowel diseases” published by NIH seems to disagree. It seems that pancreatitis (both acute and chronic) can manifest from IBD itself (not common but it happens) and drugs used to treat forms of IBD such as Crohn’s and UC definitely do cause pancreatitis. In another article “Acute pancreatitis in patients with Crohn’s disease: clinical features and outcomes” you’ll read similar discovery results. This is all just for your edification as I am not a doctor. I just read too much lol ?

  • There are some truths here but definitely some falsehoods. The cannabis industry doesn’t want to be like big tobacco at all. Please hop off of that. Second, nobody in the industry has any interest in marketing to children. That has to be dumbest concern I keep reading about.

    Why is it ok for alcohol companies to advertise EVERYWHERE? Don’t you think their adverts target the youth?

    What about the prescription pill epidemic and how pills are advertised? Their accessibility from a cupboard?

    Seriously, this was really a bad article.

    Shout out to “Say What?” in the first comment.

  • You reference percentages and don’t care to quote what they were before for the most part.. In addition, alcohol contributes far more to all the symptoms you reference, but because it’s legal and good for the economy, we’ll just pretend (legally) Its not a problem. Every point in this article is so contradictory. And for anyone that wants to comment on the youth factor, I’ve got your solution: it’s called better, more honest, open parenting. There’s so many other comments that could be said as well.. mind blown.
