Marijuana addiction has risen in places where it's legal
While legalization has benefits, a new study suggests it may have one big drawback.
- A new study finds that rates of marijuana use and addiction have gone up in states that have recently legalized the drug.
- The problem was most severe for those over age of 26, with cases of addiction rising by a third.
- The findings complicate the debate around legalization.
In a complicating bit of news for proponents of legalization, a new study shows that the rates of Cannabis use disorder have gone up dramatically in states that have legalized weed. The spike was found to be particularly high for people over the age of 26 and under the age of 17.
Cannabis Use Disorder, is that when you get so high you can’t figure out how to smoke anymore?
Cannabis use disorder, also known as CUD or cannabis/marijuana addiction, is a psychological disorder described in DSM 5 as "the continued use of cannabis despite clinically significant impairment." This includes people being unable to cut down on their usage despite wanting to, those who often use it despite finding it severely impairs their ability to function, or those who are putting themselves in danger to secure access to the drug.
While an understanding that marijuana can be addictive has existed for some time, and the image of the pothead who smokes so much they can hardly function is prevalent in our society, the effects of legalization on addiction rates have somehow gone understudied until now. Importantly, previous studies had failed to consider usage rates amongst populations over the age of 25.
In the new study, published in JAMA Psychiatry, focused on self-reported data on monthly drug use in four states where marijuana is now legal, Colorado, Washington, Alaska, and Oregon, from both before and after the drug was legalized in each state and compared it to others which have not yet legalized.
The data gave insights into the drug use habits of the respondents and specifically gave information about if they had smoked at all in the last month, the frequency of their drug use, and if they had ever had issues with how much they were using drugs.The researchers ultimately considered the responses of 505,796 individuals.
The increase in cannabis usage they found was considerable. The number of respondents over the age of 26 who claimed to have used the drug in the last month went up by 23% compared with their counterparts in states that have yet to legalize. Abuse of the drug by this group rose by 37%.
Teen usage rose by 25%, and addiction rates rose as well. This increase was small, though, and the authors have suggested it may be due to an unknown factor. The rate of usage or abuse for respondents between the ages of 18 and 25 did not increase at all.
After breaking the results down by demographics, the primary finding held; adults over the age of 26 are using marijuana more often when it is legalized, and they are starting to use it too much.
The grain of salt
As in any study where findings are self-reported, the exact numbers you see here should be taken with a grain of salt. They could be slightly higher or lower. As this study relies on people self-reporting their usage of a drug that is still illegal in many places, it is very possible that the apparent spike in addiction rates is caused by more accurate reporting, as people who live in an area where pot is still illegal may be less likely to report smoking it every day.
And it should be repeated a thousand times over that correlation and causation are not the same thing. There could be some unknown factor causing these increases in each case.
Despite these qualifications, the study is still useful in giving us a general sense of what may happen in states that have yet to legalize.
What does this mean for society and drug users?
While claims of "reefer madness" are greatly exaggerated, marijuana has several well established and thoroughly studied side effects. While occasional use isn't terribly harmful, addiction can be. Lead author Magdalena Cerdá of New York University explains in the study that heavy marijuana use is associated with "psychological and physical health concerns, lower educational attainment, decline in social class, unemployment, and motor vehicle crashes."
A substantial increase in the number of people who are addicted to the stuff will incur costs to society down the line.
Of course, a 37% increase in problematic usage means that the percentage of adults smoking too much went from .9% to 1.23% of the population responding to the survey. This makes it far less prevalent than issues with alcohol, which affected around 6% of all Americans in 2018.
Recently, Big Think's Philip Perry wrote a piece about how legalization could improve the health of millions by allowing the government to regulate the purity of commercially sold marijuana. This remains true. However, it must be weighed against the findings of this study, which suggests that at least some of these health gains will be wiped out by increased addiction rates.
What does this mean for legalization efforts?
The legalization steamroller will undoubtedly keep rolling along. While health concerns are one factor in the debate over marijuana, it is only one of many. In Illinois, where I live, weed will become legal on January 1st of 2020. The legalization campaign and legislation were more concerned with issues of social justice, the failures of prohibition, and finding a new source of tax revenue (since we're half broke) than with matters of potential addiction.
As Vox reports, the authors of the study aren't suggesting that legalization shouldn't take place; that is another, broader debate. They merely wish to present the fact that legalization has a particular side effect that we should be aware of.
While this study is unlikely to change anybody's stance on if weed should be legalized or not, it does show us a critical element to be considered when discussing drug policy. No drug is perfectly safe, and we have reason to believe that legalizing marijuana will mean that more people will have a hard time with it. Let's hope that legalization proponents keep that in mind as they rack up their victories.

Researchers documented the most common negative side effects of smoking weed, and who might be most susceptible.
- A team of researchers identified a total of 26 possible adverse reactions to cannabis use.
- Coughing fits, anxiety, and paranoia are among the top three most common adverse reactions to smoking weed.
- It was the people who smoke on a less frequent basis who were more likely to have had the bad experiences.
The most common adverse effects of pot<p>As it turns out, coughing fits are among the top three most common adverse reactions to cannabis use, along with anxiety and paranoia, according to a new study published in the <em>Journal</em><a href="https://jcannabisresearch.biomedcentral.com/articles/10.1186/s42238-019-0013-x" target="_blank"><em> of Cannabis Research</em></a>. </p><p>Now that weed is legal in the state, a team of researchers at Washington State University sought to document potential negative reactions to cannabis in order to paint a detailed picture of the effects of smoking weed for newbies. The authors surveyed more than 1,500 college students on the specific type and frequency of adverse reactions they had experienced while using pot. Additionally, the students in the study were surveyed about their demographics, personality traits, reasons for using cannabis and their use patterns. </p><p>Despite marijuana's <a href="https://bigthink.com/sex-relationships/marijuana-sex" target="_self">numerous benefits</a>, the team identified a total of <a href="https://jcannabisresearch.biomedcentral.com/articles/10.1186/s42238-019-0013-x/tables/2" target="_blank">26 possible adverse reactions to</a> the drug. More than half of the study participants reported having coughing fits along with anxiety and/or paranoia while using cannabis. The most frequently occuring of these were the coughing fits, along with chest/lung discomfort and body humming. A subset of the study group reported these reactions occurring around 30–40% of the time they were using pot. On the flip side, the three <em>least</em>-commonly reported reactions to cannabis use were fainting, visual hallucinations and cold sweats. </p><p>"There's been surprisingly little research on the prevalence or frequency of various adverse reactions to cannabis and almost no research trying to predict who is more likely to experience these types of adverse reactions," <a href="https://news.wsu.edu/2020/03/30/new-research-sheds-light-potentially-negative-effects-cannabis/" target="_blank">said Carrie Cuttler</a>, assistant professor of psychology and an author on the paper, according to WSU News. "With the legalization of cannabis in Washington and 10 other states, we thought it would be important to document some of this information so that more novice users would have a better sense of what types of adverse reactions they may experience if they use cannabis."</p><p>The most distressing of the 26 negative reactions were panic attacks, fainting, and vomiting. Yet, the survey data suggested that cannabis users generally do not find even acute adverse reactions to cannabis to be severely distressing.</p>
