Greater than two million People with coronary heart illness at the moment use or have used marijuana, based on a examine printed in 2020 within the Journal of the American Faculty of Cardiology. This can be dangerous, says Robert A. Kloner, MD, chief science officer and director of cardiovascular analysis at Huntington Medical Analysis Institutes in Pasadena, California.

One examine, printed in 2016 within the Journal of Hypertension, discovered that latest marijuana use was linked to increased systolic blood strain ranges. Systolic blood strain measures the strain of blood within the arteries when the guts beats. Diastolic blood strain measures the pressure when the guts is at relaxation between beats.

Within the examine of individuals aged 20 to 59, about 1500 individuals who used marijuana prior to now 30 days have been in comparison with roughly 5,000 never-users and 5,000 individuals who had used marijuana prior to now, however not within the final 30 days.

Primarily based on the outcomes, the researchers estimated that utilizing marijuana each day for 30 days would lead to a systolic blood strain about 3 factors increased than individuals who by no means used it or used it prior to now. This “modest affiliation” jibes with different research which have discovered marijuana could cause a brief time period rise in blood strain however the long-term influence is much less clear, they concluded.

One other examine based mostly on comparable nationwide survey information was printed in 2019 in The American Journal of Well being Habits. That examine discovered that present heavy customers of marijuana have been 1.8 occasions extra prone to have hypertension than their counterparts who by no means used marijuana. Of people that used marijuana a number of occasions within the final 30 days, 19.4 p.c had elevated blood strain, 22.7 p.c had stage 1 hypertension, and 12.9 p.c had stage 2 hypertension, in contrast with 16.1 p.c, 21.4 p.c, and 11.9 p.c of by no means customers.

In a 2019 analysis letter in Mayo Clinic Proceedings, Ohio researchers reported that individuals who used hashish had a 1.7-fold increased danger of coronary heart assault than comparable folks the identical age who didn’t use it. Though the hashish customers had different danger components like weight problems, hypertension, sort 2 diabetes, and different drug use, like tobacco, alcohol, and cocaine, their coronary heart assault danger was increased even after taking these into consideration. Over a 3-year interval, the findings recommend that 1.37 p.c of hashish customers would have a coronary heart assault in contrast with 0.54 p.c of non-users.

“There’s growing proof that marijuana use might set off coronary heart assaults in some people,” says Dr. Kloner, who can also be a professor of medication on the Keck Faculty of Medication at College of Southern California in Los Angeles. “States the place marijuana use has been legalized have seen will increase in emergency ward visits and hospitalizations for marijuana-related unwanted effects, together with a rise in coronary heart assaults, particularly in younger males.”

Precisely how marijuana may elevate the danger for coronary heart assault isn’t absolutely understood. However the drug might trigger your sympathetic nervous system to launch the stress hormones adrenaline and cortisol, growing coronary heart price and blood strain.

There are extra questions that must be answered earlier than consultants can draw any conclusions about marijuana, hypertension, and the guts.

The potential results of THC vs. CBD

Lots of the uncertainty might come all the way down to the elements within the bud resembling THC (delta-9-tetrahydrocannabinol) and CBD (cannabidiol), says Dr. Kloner. THC and CBD are two of the primary compounds present in hashish vegetation resembling marijuana and hemp. Marijuana comprises rather more THC than hemp, whereas hemp boasts extra CBD. (Right here’s the distinction between CBD vs. THC.)

The 2 compounds act very otherwise within the physique. “CBD may very well have some helpful results on the cardiovascular system, whereas THC tends to stimulate the sympathetic nervous system and could also be extra deleterious,” Dr. Kloner says.

Plus, he factors out, you don’t all the time understand how a lot of both you’re getting in any preparation. “The online outcomes might rely upon the general focus of those elements within the marijuana pattern and the way the person responds to the elements,” he says.

Some folks flip to marijuana to cut back anxiousness or stress, each of which may trigger direct and oblique will increase in blood strain.

“As a normal rule, I’d not prescribe marijuana to decrease blood strain,” Dr. Kloner says. “There are well-proven way of life modifications in addition to medicines which decrease blood strain and have been proven to cut back [heart attacks and stroke].” These embody consuming a low-sodium weight-reduction plan, partaking in common bodily exercise—particularly cardio train like brisk strolling—consuming alcohol solely carefully, and never smoking.
