Abstract: Hashish use will increase the danger of extreme sickness from COVID-19. Analyzing information of 72,501 sufferers, researchers found that hashish customers had been considerably extra more likely to require hospitalization and intensive care.
This elevated danger was similar to that of tobacco people who smoke. The examine challenges the notion of hashish as a protected substance within the context of COVID-19.
Key Info:
- Larger Hospitalization Charges: Hashish customers had been 80% extra more likely to be hospitalized with COVID-19.
- Elevated ICU Admissions: Hashish customers had a 27% larger probability of needing intensive care.
- Corresponding to Tobacco: The danger of extreme COVID-19 outcomes from hashish use is much like that from smoking tobacco.

Because the lethal illness that got here to be generally known as COVID-19 began spreading in late 2019, scientists rushed to reply a important query: Who’s most in danger?
They rapidly acknowledged {that a} handful of traits — together with age, smoking historical past, excessive physique mass index (BMI) and the presence of different illnesses equivalent to diabetes — made folks contaminated with the virus more likely to turn out to be critically in poor health and even die.
However one steered danger issue stays unconfirmed greater than 4 years later: hashish use. Proof has emerged over time indicating each protecting and dangerous results.
Now, a brand new examine by researchers at Washington College College of Medication in St. Louis factors decisively to the latter: Hashish is linked to an elevated danger of great sickness for these with COVID-19.
The examine, revealed June 21 in JAMA Community Open, analyzed the well being information of 72,501 folks seen for COVID-19 at well being facilities in a significant Midwestern health-care system through the first two years of the pandemic.
The researchers discovered that individuals who reported utilizing any type of hashish not less than as soon as within the yr earlier than growing COVID-19 had been considerably extra more likely to want hospitalization and intensive care than had been folks with no such historical past. This elevated danger of extreme sickness was on par with that from smoking.
“There’s this sense among the many public that hashish is protected to make use of, that it’s not as dangerous in your well being as smoking or ingesting, that it could even be good for you,” mentioned senior writer Li-Shiun Chen, MD, DSc, a professor of psychiatry.
“I believe that’s as a result of there hasn’t been as a lot analysis on the well being results of hashish as in comparison with tobacco or alcohol. What we discovered is that hashish use isn’t innocent within the context of COVID-19.
“Individuals who reported sure to present hashish use, at any frequency, had been extra more likely to require hospitalization and intensive care than those that didn’t use hashish.”
Hashish use was totally different than tobacco smoking in a single key consequence measure: survival. Whereas people who smoke had been considerably extra more likely to die of COVID-19 than nonsmokers — a discovering that matches with quite a few different research — the identical was not true of hashish customers, the examine confirmed.
“The impartial impact of hashish is much like the impartial impact of tobacco relating to the danger of hospitalization and intensive care,” Chen mentioned. “For the danger of loss of life, tobacco danger is obvious however extra proof is required for hashish.”
The examine analyzed deidentified digital well being information of people that had been seen for COVID-19 at BJC HealthCare hospitals and clinics in Missouri and Illinois between Feb. 1, 2020, and Jan. 31, 2022.
The information contained knowledge on demographic traits equivalent to intercourse, age and race; different medical situations equivalent to diabetes and coronary heart illness; use of gear together with tobacco, alcohol, hashish and vaping; and outcomes of the sickness — particularly, hospitalization, intensive-care unit (ICU) admittance and survival.
COVID-19 sufferers who reported that they’d used hashish within the earlier yr had been 80% extra more likely to be hospitalized and 27% extra more likely to be admitted to the ICU than sufferers who had not used hashish, after taking into consideration tobacco smoking, vaccination, different well being situations, date of prognosis, and demographic components.
For comparability, tobacco people who smoke with COVID-19 had been 72% extra more likely to be hospitalized and 22% extra more likely to require intensive care than had been nonsmokers, after adjusting for different components.
These outcomes contradict another analysis suggesting that hashish might assist the physique battle off viral illnesses equivalent to COVID-19.
“A lot of the proof suggesting that hashish is nice for you comes from research in cells or animals,” Chen mentioned.
“The benefit of our examine is that it’s in folks and makes use of real-world health-care knowledge collected throughout a number of websites over an prolonged time interval. All of the outcomes had been verified: hospitalization, ICU keep, loss of life. Utilizing this knowledge set, we had been in a position to verify the well-established results of smoking, which means that the info are dependable.”
The examine was not designed to reply the query of why hashish use may make COVID-19 worse. One chance is that inhaling marijuana smoke injures delicate lung tissue and makes it extra susceptible to an infection, in a lot the identical manner that tobacco smoke causes lung injury that places folks susceptible to pneumonia, the researchers mentioned.
That isn’t to say that taking edibles can be safer than smoking joints. It’s also potential that hashish, which is thought to suppress the immune system, undermines the physique’s capacity to battle off viral infections irrespective of how it’s consumed, the researchers famous.
“We simply don’t know whether or not edibles are safer,” mentioned first writer Nicholas Griffith, MD, a medical resident at Washington College. Griffith was a medical pupil at Washington College when he led the examine.
“Folks had been requested a yes-or-no query: ‘Have you ever used hashish previously yr?’ That gave us sufficient info to ascertain that in the event you use hashish, your health-care journey will likely be totally different, however we are able to’t understand how a lot hashish it’s a must to use, or whether or not it makes a distinction whether or not you smoke it or eat edibles.
“These are questions we’d actually just like the solutions to. I hope this examine opens the door to extra analysis on the well being results of hashish.”

Summary
Hashish, Tobacco Use, and COVID-19 Outcomes
Significance
It’s unclear whether or not hashish use is related to antagonistic well being outcomes in sufferers with COVID-19 when accounting for recognized danger components, together with tobacco use.
Goal
To look at whether or not hashish and tobacco use are related to antagonistic well being outcomes from COVID-19 within the context of different recognized danger components.
Design, Setting, and Contributors
This retrospective cohort examine used digital well being report knowledge from February 1, 2020, to January 31, 2022. This examine included sufferers who had been recognized as having COVID-19 throughout not less than 1 medical go to at a big educational medical middle within the Midwest US.
Exposures
Present hashish use and tobacco smoking, as documented within the medical encounter.
Essential Outcomes and Measures
Health outcomes of hospitalization, intensive care unit (ICU) admission, and all-cause mortality following COVID-19 an infection. The affiliation between substance use (hashish and tobacco) and these COVID-19 outcomes was assessed utilizing multivariable modeling.
Outcomes
A complete of 72 501 sufferers with COVID-19 had been included (imply [SD] age, 48.9 [19.3] years; 43 315 [59.7%] feminine; 9710 [13.4%] had present smoking; 17 654 [24.4%] had former smoking; and 7060 [9.7%] had present use of hashish). Present tobacco smoking was considerably related to elevated danger of hospitalization (odds ratio [OR], 1.72; 95% CI, 1.62-1.82; P < .001), ICU admission (OR, 1.22; 95% CI, 1.10-1.34; P < .001), and all-cause mortality (OR, 1.37, 95% CI, 1.20-1.57; P < .001) after adjusting for different components.
Hashish use was considerably related to elevated danger of hospitalization (OR, 1.80; 95% CI, 1.68-1.93; P < .001) and ICU admission (OR, 1.27; 95% CI, 1.14-1.41; P < .001) however not with all-cause mortality (OR, 0.97; 95% CI, 0.82-1.14, P = .69) after adjusting for tobacco smoking, vaccination, comorbidity, prognosis date, and demographic components.
Conclusions and Relevance
The findings of this cohort examine recommend that hashish use could also be an impartial danger issue for COVID-19–associated problems, even after contemplating cigarette smoking, vaccination standing, comorbidities, and different danger components.
