New analysis exhibits that marijuana has not been linked to hypertension

A study by an international team of researchers found that current or past use of marijuana is not independently linked to an increased risk of high blood pressure. The results of the study “The Longitudinal Relationship Between Cannabis Use and High Blood Pressure” were posted online last month prior to publication in the journal Drug and Alcohol Review.

To complete the study, researchers from the United States, Canada, Germany, and Russia examined the association between marijuana use and high blood pressure in a nationally representative sample of subjects. Over a period of three years, the researchers monitored the health of participants, all of whom did not have high blood pressure at the start of the study.

The researchers then performed an analysis of the data to quantify the relationships between lifelong cannabis use, 12 month cannabis use, and 12 month cannabis use frequency (at least monthly use and less than monthly use) and the incidence of hypertension.

In the initial analysis, the data showed that “cannabis use was associated with a reduced incidence of hypertension in the unadjusted analyzes. However, relationships were confused due to age. “

“After adjusting for all confounding factors, neither lifelong cannabis use, 12-month cannabis use nor 12-month cannabis use frequency were randomly associated with the occurrence of high blood pressure,” wrote the authors of the study.

Study consistent with previous research

The study’s results are in line with separate research published last month that showed that cannabis use can actually lower blood pressure in older adults. A report on the research, “Cannabis is Associated with Lowering Blood Pressure in Older Adults – A 24-Hour Ambulatory Blood Pressure Monitoring Study” appeared in the European Journal of Internal Medicine.

The researchers examined 26 elderly patients and monitored their blood pressure and other readings over a period of three months. The subjects in the study consumed cannabis through smoking or through oral cannabis oil extracts.

“Three months of cannabis treatment was associated with lowering systolic and diastolic blood pressure and heart rate,” the study’s authors concluded.

The researchers found that the lowest blood pressure readings were recorded three hours after cannabis use. While a drop in blood pressure was noted both during the day and at night, the drop was more significant at night.

Dr. Ran Abuhasira of the Faculty of Health Sciences at Ben Gurion University and BGU-Soroka Cannabis Clinical Research Institute said there is a lack of research into the effects of cannabis on the health of seniors.

“Older adults are the fastest growing group of medical cannabis users, but there is little evidence of cardiovascular safety for this population,” Abuhasira said. “This study is part of our ongoing effort to conduct clinical research into the true physiological effects of cannabis over time.”

In addition, a meta-analysis of existing data published in the journal Neuropharmacology found that additional research could lead to new therapies for cardiovascular diseases including high blood pressure.

“The endocannabinergic system plays an important cardiovascular regulatory role not only in pathophysiological conditions associated with excessive hypotension, but also in high blood pressure,” the authors wrote. “Therefore, the pharmacological manipulation of this system can offer new therapeutic approaches in a wide variety of cardiovascular diseases.”
