Cannabis Use Linked to Higher Risk of Heart Attack and Stroke, Study Finds

Boston, Massachusetts United States of America
Cannabis use is associated with a higher risk of heart attack and stroke, according to new research. The study found that daily cannabis use increases the risk of heart attack by 25% and stroke by 42%, compared to nonusers.
While both daily and non-daily users had an increased risk of cardiovascular disease, the increase was more pronounced in those who used cannabis regularly.
Cannabis Use Linked to Higher Risk of Heart Attack and Stroke, Study Finds

Cannabis use is associated with a higher risk of heart attack and stroke, according to new research. The study found that daily cannabis use increases the risk of heart attack by 25% and stroke by 42%, compared to nonusers. While both daily and non-daily users had an increased risk of cardiovascular disease, the increase was more pronounced in those who used cannabis regularly.

The study also found that smoking, vaping or eating marijuana is linked to a significantly higher risk of heart attack and stroke than not using any form of cannabis. The researchers looked at data from 2016 to 2020 in an annual survey conducted by the U.S. Centers for Disease Control and Prevention that asked people about their drug use, drinking, exercise, and sleep habits.

The study comes as more Americans are using cannabis frequently and more states are legalizing it for medicinal or recreational purposes. The researchers caution that while the findings suggest a link between cannabis use and cardiovascular disease risks, further research is needed to confirm these results.

  • Unique Points
    • Smoking weed daily is associated with a 25% increased risk of heart attack and 42% increased risk of stroke when compared to not using the drug.
    • Daily cannabis use, primarily by smoking, is associated with a higher risk of heart attack and stroke than weekly usage.
  • Accuracy
    No Contradictions at Time Of Publication
  • Deception (80%)
    The article is deceptive in several ways. Firstly, it states that smoking cannabis has significant cardiovascular risks just like smoking tobacco. However, the study does not compare the risk of heart attack and stroke between daily marijuana users and non-users who smoke or vape tobacco. The study only compares daily marijuana use to non-use of any substance including cigarettes or vaping products.
    • The article quotes Abra Jeffers as saying that smoking cannabis is linked to a significantly higher risk of heart attack and stroke even if a person had no existing heart conditions, but this statement contradicts the findings of the study which only found an increased risk for daily marijuana users.
    • The article states that smoking cannabis has significant cardiovascular risks just like smoking tobacco, but the study does not compare the risk of heart attack and stroke between daily marijuana users and non-users who smoke or vape tobacco.
  • Fallacies (85%)
    The article contains several fallacies. The author uses an appeal to authority by citing a study and stating that the findings are significant. However, this does not necessarily mean that the study is reliable or unbiased. Additionally, the author makes a false dilemma by presenting only two options: using marijuana or smoking tobacco as if they are mutually exclusive when in fact there may be other forms of consumption available for both substances. The author also uses inflammatory rhetoric by stating that cannabis smoke is not all that different from tobacco smoke, which could potentially lead to a false sense of urgency and fear among readers. Finally, the author makes an informal fallacy by using statistics without providing context or explaining how they were obtained.
    • The study found that smoking cannabis has significant cardiovascular risks just like smoking tobacco.
  • Bias (100%)

  • Site Conflicts Of Interest (50%)
    The author of the article has a conflict of interest with Abra Jeffers and Massachusetts General Hospital in Boston. The author also has a professional affiliation with University of Colorado Skaggs School of Pharmacy and Pharmaceutical Sciences in Aurora, Colorado.
    • Abra Jeffers is quoted extensively throughout the article despite not being an expert on the topic.
    • Author Conflicts Of Interest (50%)
      The author has a conflict of interest on the topic of marijuana and its effects on cardiovascular disease. The article mentions that Abra Jeffers is an advocate for medical cannabis and works at Massachusetts General Hospital in Boston, which may compromise her ability to report objectively.

        The article is deceptive in several ways. Firstly, it states that smoking weed daily is associated with a 25% increased risk of heart attack and 42% increased risk of stroke when compared to not using the drug. However, this statement implies that there are no other factors at play which could contribute to these risks such as age or family history. This is false because it has been established in previous studies that smoking weed can increase the likelihood of developing heart disease and stroke regardless of whether someone smokes tobacco or not.

        • The article states that smoking weed daily is associated with a higher risk of heart attack and stroke but it does not provide any evidence on how cannabis affects cardiovascular tissues.
      • Fallacies (85%)
        The article contains an appeal to authority fallacy by stating that smoking cannabis appears to also be a risk factor for cardiovascular disease. The author cites the study as evidence but does not provide any information on how the researchers came to this conclusion or what other studies have found regarding this topic.

          • Unique Points
            • Smoking cannabis can cause serious heart problems and raise the risk of a stroke.
            • Cannabis is illegal at the federal level, however Washington and 24 other states have legalised the use of recreational cannabis.
          • Accuracy
            • Daily use of cannabis increases the risk of heart attack by 25% and stroke by 42% compared to nonusers.
          • Deception (40%)
            The article is deceptive in several ways. Firstly, it implies that smoking cannabis is harmless and only causes cardiovascular disease risks when used daily. However, the study shows that even low-level use of cannabis can increase the risk of heart attack and stroke by 25% and 42%, respectively. Secondly, the article states that Germany has decriminalised cannabis but does not mention its legal status in other countries or regions where it is still illegal. This creates a false sense of safety for readers who may believe that cannabis use is now completely legal and safe everywhere. Lastly, the article quotes Dr Abra Jeffers as saying that previous research suggested that cannabis could be associated with cardiovascular disease, but fails to mention any specific studies or evidence supporting this claim.

            • The study found a 42% higher risk of stroke for daily cannabis users compared to non-users. This is deceptive because it implies that only heavy use of cannabis can cause such risks.
          • Fallacies (85%)
            The article contains an appeal to authority fallacy by citing a study published in the Journal of the American Heart Association without providing any context or information about the credibility of the journal. The author also uses inflammatory rhetoric when stating that cannabis is perceived as harmless and people have not considered it dangerous to their health, which could be seen as an attempt to manipulate public opinion.
            • Smoking cannabis can cause serious heart problems and raise the risk of a stroke
            • Despite common use, little is known about the risks of cannabis use and, in particular, the cardiovascular disease risks. The perceptions of the harmfulness of smoking cannabis are decreasing.
            • Cannabis smoke is not all that different from tobacco smoke
          • Bias (85%)
            The article presents a biased view of the harmlessness of cannabis use. The author uses language that dehumanizes and demonizes those who smoke cannabis by saying 'little is known about the risks' and 'perceptions of harmfulness are decreasing'. This implies that people who smoke cannabis are ignorant or foolish, which is not true. Additionally, the article presents a disproportionate number of quotes from experts warning about the dangers of smoking cannabis without providing any counter-arguments or evidence to refute these claims.
