According to Barbara A Yankey, the lead author and a PhD student in the School of Public Health, Georgia State University, Atlanta, various steps had been taken in the U.S towards the legalisation and decriminalisation of marijuana and as a result, there might occur a considerable rise in the rates of use of recreational marijuana.
Yankey et al gathered data on individuals ages 20 and older who reported information on their marijuana use from 2005 to 2006 through the US National Health and Nutrition Examination Survey (NHANES).
The study also tracked the causes of death for people who admitted to ever using marijuana.
A study has shown that the risk of death from hypertension (also known as high blood pressure) is higher for cannabis users than for non-users - and is even higher than for those who smoke cigarettes. As per the findings that published in the European Journal of Preventive Cardiology among a total of 1,213 participants, marijuana users had a higher risk of dying from hypertension. Compared to non-users, marijuana users had a 3.42-times higher risk of death from hypertension and a 1.04 greater risk for each year of use.
"It could be these elevations in blood pressure are a manifestation of marijuana being laced with other things that are more cardio-stimulating", Lawrence said. The researchers estimated the associations of marijuana use, and duration of use, with death from hypertension, heart disease, and cerebrovascular disease, controlling for cigarette use and demographic variables including sex, age, and ethnicity.
The cardiovascular risk associated with marijuana use may be greater than the cardiovascular risk already established for cigarette smoking, the researchers said.
A new study has found that smoking marijuana could have a surprising health risk.
Results suggest marijuana use is more unsafe for heart health than cigarettes, despite certain campaigners insisting cannabis is safer than tobacco.
Yankey said the sample size of her study was too small to capture the associations between pot use and specific heart-related conditions such as stroke.
Neither cumulative lifetime nor recent use of marijuana is associated with the incidence of [cardiovascular disease].
Armentano acknowledged that cannabinoids (a class of chemicals found in marijuana, - the most well-known is THC, a psychoactive) do affect blood pressure - a subject that he has written about previously.
