This article is directed to those of you who use marijuana as a drug of escape, to get high. For those of you who are truly using it to heal disease, you just need to be aware and weigh the benefits against the risk if you have high blood pressure. ~NationalAddictionNews.com
In a recent study, researchers found that marijuana use is linked to a three-fold risk of death from high blood pressure.
The study was conducted by a team from Georgia State University.
Currently, there is little research on the impact of marijuana use on cardiovascular and cerebrovascular mortality.
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.
In 2005–2006, the participants of the study were asked if they had ever used marijuana. Those who answered “yes” were considered marijuana users.
They reported the age when they first tried marijuana and this was subtracted from their current age to calculate the duration of use.
Information on marijuana use was merged with mortality data in 2011 from the National Centre for Health Statistics.
The team 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.
The team found that 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.
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 link between marijuana use and death from heart disease or cerebrovascular disease.
The researchers suggest that marijuana users had a greater than three-fold risk of death from hypertension and the risk increased with each additional year of use.
There were limitations to the way marijuana use was estimated. For example, it cannot be certain that participants used marijuana continuously since they first tried it.
The results suggest a possible risk of hypertension mortality from marijuana use.
This is not surprising since marijuana is known to have a number of effects on the cardiovascular system.
Marijuana stimulates the sympathetic nervous system, leading to increases in heart rate, blood pressure and oxygen demand.
Emergency rooms have reported cases of angina and heart attacks after marijuana use.
The authors stated that the cardiovascular risk associated with marijuana use may be greater than the cardiovascular risk already established for cigarette smoking.
However, the number of smokers in our study was small and this needs to be examined in a larger study.
The team suggests that it was crucial to understanding the effects of marijuana on health so that policymakers and individuals could make informed decisions.
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.
