- The effects of marijuana on cardiac and neurological health remain complex and somewhat ambiguous, with challenges arising due to legal, ethical, and other hurdles in research.
- Marijuana usage and its impact may vary significantly based on factors such as personal usage, product composition, active components, usage frequency and duration, and age of the user.
- The distinction between recreational and medicinal usage is essential when discussing marijuana’s health impact, with chronic, heavy recreational usage potentially negatively affecting cognitive function, but medicinal usage possibly offering cognitive benefits.
- Marijuana usage also presents different outcomes for heart health, possibly enhancing blood pressure with sustained exposure to THC in recreational marijuana or decreasing blood pressure in older individuals using medicinal marijuana.
- One of the main challenges of conducting clinical research on marijuana consumption is its classification as a highly abusive substance by the federal government, leading to significant restrictions on research materials.
As countless states across America relax their laws on marijuana, both for medical and recreational purposes, many are left wondering about the potential health impact of this widespread herb. Despite its decriminalization or legalization, key queries persist about whether marijuana usage may be beneficial or detrimental.
Research scientists have been quick to recognize that the real situation is far from straightforward. The effects of marijuana, also referred to as cannabis, on cardiac and neurological health have been investigated for several years, yet the complexities of this plant and its influence remain somewhat ambiguous.
Ramifications on Heart and Brain – A Complex Puzzle
“While animal studies indicate potential consequences for the heart and brain, human data isn’t as clear,” notes neurologist Dr. Fernando Daniel Testai, from the University of Chicago Department of Neurology and Rehabilitation. He led the team that published a scientific statement detailing what is currently known and unknown about cannabis effects on brain function.
Several key factors come into play, explains Staci Gruber, an associate professor of psychiatry at Harvard Medical School. Personal usage, product composition, active components, usage frequency and duration, as well as the age of the user, all potentially factor into the equation. However, legal, ethical, and other hurdles create considerable challenges for researchers attempting to clarify these parameters.
Marijuana: A Diverse Spectrum of Use and Impact
With approximately 48 million people aged 12 or above reporting they used marijuana in 2019, an increase from 11% to 18% over the last two decades, understanding its effect on health is critical.
When discussing the health impact of marijuana, it’s essential to differentiate between recreational and medicinal usage. “Recreational users typically seek high THC content products, whereas medical users may not necessarily want to get ‘high’; they simply want relief from their symptoms,” says Gruber.
Research indicates that chronic, heavy recreational usage could negatively affect cognitive function, particularly when commenced during adolescence. However, adults consuming cannabis for health reasons may achieve cognitive benefits.
The way different people use marijuana also presents different outcomes for heart health. Sustained elevated exposure to THC, the mind-altering compound found in recreational marijuana, can enhance blood pressure. However, older individuals employing medical marijuana may note a decrease in blood pressure levels.
The Intricacies and Challenges of Cannabis Research
Direct comparison of the effects of medical and recreational marijuana in a research setting could yield more valid information, suggests Testai. “Currently, assessment of marijuana exposure relies heavily on user self-reporting, presenting no objective data on consumption,” he pointed out.
Moreover, recreational usage often overlaps with the use of other potentially mind-altering methods or substances. This creates difficulty in determining potential health impacts caused specifically by marijuana.
Conducting clinical research on marijuana consumption poses its own unique challenges. Marijuana is still classified as a highly abusive substance by the federal government, resulting in considerable restrictions on research materials. Gruber remarks that the marijuana supplied for research purposes doesn’t match what most consumers use at home.
Brain development also holds considerable weight in the discussion. Early marijuana usage during developmental periods could carry higher cognitive risk than if usage begins during adulthood. However, researchers face the challenge of setting up a placebo control group due to the unmaskable effect of marijuana.
“Only through creative thinking can we capture observational data accurately and conduct valid clinical trials,” Gruber concludes, reflecting on the future of this exciting research area.
