A new study has found that daily cannabis use increases the risk of developing cardiovascular disease. The researchers analyzed data on how often 175,000 people used cannabis and the extent of their cardiovascular disease. They found a causal relationship between years of daily consumption and an increased risk of heart disease.
“A growing body of evidence suggests that cannabis is not entirely harmless and may cause cardiovascular disease,” said study lead author Dr. Ishan Paranjpe, a medical resident at Stanford University.
The study found that daily cannabis users were 34% more likely to develop coronary heart disease than those who never used it. It also found that people who consumed weed only once a month or less were not at significant risk.
The results of the study were confirmed even after the researchers ruled out other potential causes of coronary heart disease, such as age, gender, and major risk factors for cardiovascular disease - high blood pressure, high cholesterol, type 2 diabetes, obesity, smoking, and alcohol use.
However, the new study was unable to find out whether different types of cannabis use, such as eating foods versus smoking weed, affect the risk of heart disease. But because THC enters the brain more quickly when smoked, the researchers say future studies should explore different uses and their effects on the heart.
