Weed smokers, marijuana may triple your chances of dying from high BP

A study found that marijuana users had a greater than three-fold risk of death from hypertension and the risk increased with each additional year of use.

Turns out, it’s not just cigarettes that risk your heart as according to a recent study, marijuana smokers have triple the death risk from high blood pressure (BP). In the absence of longitudinal data on marijuana use, the researchers designed a retrospective follow-up study of NHANES (National Health and Nutrition Examination Survey) participants aged 20 years and above.

Information on marijuana use was merged with mortality data in 2011 from the National Centre for Health Statistics. 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. Death from hypertension included multiple causes such as primary hypertension and hypertensive renal disease.

Among a total of 1,213 participants, 34% used neither marijuana nor cigarettes, 21% used only marijuana, 20% used marijuana and smoked cigarettes, 16% used marijuana and were past-smokers, 5% were past-smokers and 4% only smoked cigarettes. The average duration of marijuana use was 11.5 years.

The cardiovascular risk associated with marijuana use may be greater than the risk already established for cigarette smoking.

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. There was no association between marijuana use and death from heart disease or cerebrovascular disease.

The authors stated that the cardiovascular risk associated with marijuana use may be greater than the cardiovascular risk already established for cigarette smoking. She noted that it was crucial to understand the effects of marijuana on health so that policy makers and individuals could make informed decisions.

She said: “Support for liberal marijuana use is partly due to claims that it is beneficial and possibly not harmful to health. With the impending increase in recreational marijuana use it is important to establish whether any health benefits outweigh the potential health, social and economic risks. If marijuana use is implicated in cardiovascular diseases and deaths, then it rests on the health community and policy makers to protect the public.”
