A new study analyzed several years of surveys on increases in marijuana and cannabis consumption.
People who frequently smoke marijuana have a higher risk of heart attack and stroke, according to a study published on Wednesday.
The article, published in The Journal of the American Heart Association, is an analysis of responses to the U.S. government’s annual survey on behavioral risk from 2016 to 2020.
The respondents answered health questions, including reporting their own health problems related to heart disease.
About 4 percent of the respondents reported daily marijuana use, which the researchers suggested raised the chance of a heart attack by 25 percent and of a stroke by 42 percent. Among those who never smoked tobacco, daily use was tied to a 49 percent higher risk of heart attack and a more than doubled risk of stroke, the study indicated.
About three-quarters of the respondents said that smoking was their main method of using weed. The other quarter consumed it by vaping, through edibles or drinking it.
“Cannabis smoke releases the same toxins and particulate matter that tobacco does,” said the study’s first author, Abra M. Jeffers, a data analyst at Massachusetts General Hospital in Boston. She conducted the analysis during her post-doctoral fellowship at the University of California, San Francisco.
