"Marijuana stimulates the sympathetic nervous system, leading to increases in heart rate, blood pressure, and oxygen demand", said study co-leader Barbara Yankey of Georgia State University in Atlanta.
Cardiovascular diseases constitute the leading cause of death worldwide, despite majority being preventable. 34% of them 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. Eleven and a half years was the average duration of marijuana use.
Armentano also argued that this new study's results are also jeopardized because of the ambiguous definition of "marijuana user".
Information on marijuana use was merged with mortality data in 2011 from the National Centre for Health Statistics.
"Compared with no marijuana use, cumulative lifetime and recent marijuana use showed no association with incident CVD [cardiovascular disease], stroke, or transient ischemic attacks, coronary heart disease, or CVD mortality", the authors of that study wrote.
It's critically important for people with type 2 diabetes - those who have known risk factors for heart disease and those who don't - to follow their doctors' advice for lowering their heart disease risk. They were also asked to report the age in which they first tried using marijuana.
A Quinnipiac University poll found 94 percent of USA voters think medical marijuana should be legal. For example, it can not be certain that participants used marijuana continuously since they first tried it. We conducted Cox proportional hazards regression analyses to estimate hazard ratios for hypertension, heart disease, and cerebrovascular mortality due to marijuana use.
Researchers enrolled 1,213 National Health and Nutrition Examination Survey participants aged at least 20 years in a retrospective study who answered "yes" or "no" questions on the recreational use of marijuana.
According to Ms. Yankey, harmful effects of marijuana on the functioning of the brain are more than that of cigarette smoking.
"We found higher estimated cardiovascular risks associated with marijuana use than cigarette smoking", Ms. Yankey concluded. "However, the number of smokers in our study was small, and this needs to be examined in a larger study". Also, in order to make informed decisions, it is vital for individuals as well as the policy makers to understand the impact of marijuana on health. There was however no association between marijuana use and death from heart disease or cerebrovascular disease. For each year of marijuana use, the risk of death from hypertension increased by 1.04 times.
