Public debate over marijuana has persisted for decades, and recent legislative changes across the United States indicate that the public is much more accepting of marijuana as both a medical product and a recreational drug than previous generations. There have been numerous studies about the potential health benefits of cannabis, but the federal Schedule I classification of marijuana hampers many scientific research efforts. Despite this, the push for legalization across the U.S. appears to continue picking up steam. Unfortunately, this may lead to an unintended public health risk due to the often-overlooked health implications associated with marijuana use.
Marijuana’s Impact On Physical Health
A recent Georgia State University (GSU) clinical study* examined the long-term medical effects of marijuana use with a study group of 1,213 participants. The participants in the study had varying levels of marijuana use. 34% of participants did not smoke marijuana or cigarettes at all while 21% only used marijuana. Another 20% used both marijuana and cigarettes, 16% were past cigarette smokers who now only smoke marijuana, and 5% were past smokers with the final 4% only smoking cigarettes.
The reasoning behind arranging these control groups in this manner is to pinpoint trends commonly seen among both tobacco and marijuana users as both can produce similar respiratory, cardiovascular, and neurological effects over time. Marijuana effects can include diminished heart health, neurological deficiencies, and other substantial medical issues.
Heart Conditions From Marijuana Use
Marijuana effects on heart health can be significant. The GSU study concluded that marijuana users face a 3.42-times higher risk of developing fatal high blood pressure, and that risk increases about 1.04 times with each year of use. One of the physiological effects of cannabis is stimulation of the sympathetic nervous system. This leads to increased oxygen demand, higher blood pressure, and increased heart rate. Over time, these symptoms stress heart function in dramatic ways, potentially causing chronic medical conditions or even fatal cardiac problems.
Increased Risk Of Heart Failure And Stroke
Marijuana’s effect on blood pressure can be staggering. Research on hospital admissions for people between the ages of 18 and 55 from 2009 and 2010 indicated that marijuana users faced a much higher risk of stroke, coronary artery disease, and heart failure. The GSU study also concluded that marijuana users face a 26% higher risk of suffering strokes and a 10% increased risk of heart failure. People struggling with marijuana use disorder are effectively increasing their risk of heart failure and stroke the longer they continue using marijuana.
The American Heart Association has also reported that marijuana use increases the risk of developing a condition known as stress cardiomyopathy. The symptoms of this condition include a sudden short-term weakening of heart function. The heart’s ability to pump blood diminishes, resulting in symptoms similar to a heart attack including chest pain, dizziness, shortness of breath, fatigue, and even fainting. The study reported that marijuana users face nearly twice the usual risk of developing stress cardiomyopathy than non-users.
Marijuana’s Effect On Brain Functions
Marijuana’s effect on the brain includes both short-term and long-term symptoms, and the time at which a person begins using marijuana has a significant impact on mental health. In the short-term, a person who uses cannabis will likely experience euphoria, relaxation, and stress relief. However, short-term effects of marijuana can also include a distorted sense of time or reality, the inability to control one’s thoughts, memory problems, and even hallucinations. There have also been recorded incidents of marijuana-induced psychosis in individuals with underlying psychological issues.
In the long-term, marijuana can impede psychological development and impact learning ability. Teens who use marijuana are more likely to develop behavioral and learning difficulties. A New Zealand-based study** concluded that the average person who starts using cannabis in the teenage years loses an average of 8 IQ points between the ages of 13 and 38. Early marijuana use also correlates heavily with lower verbal ability and general knowledge.
Potential Dangers Of Widespread Cannabis Legalization
Several states including California, Oregon, Washington, and Alaska have legalized recreational marijuana sales, and many more have enacted legislation approving medical marijuana sales for patients with qualifying conditions***. There are many driving forces behind the push for legalization, including:
- Public opinion. A recent Gallup poll reported that more than 60% of Americans support marijuana legalization or some type or marijuana law reform. Conservative support for marijuana legalization has also increased tremendously in recent years.
- Reallocation of drug crime funding. Marijuana legalization inherently leads to less law enforcement resources spent pursuing marijuana-related crimes. This allows law enforcement to spend more time and money focusing on more dangerous drugs like heroin, methamphetamine, and prescription pills used for recreation.
- Medical value. Marijuana can be an effective treatment for several medical conditions**** like anxiety, depression, fibromyalgia, chronic pain, Crohn’s disease and other bowel disorders, eating disorders, panic disorders, endometriosis, and cancer. However, it is vital for medical marijuana users to carefully follow physician instructions and recognize the potential for medical harm and abuse that marijuana can create.
- Revenue. States that have legalized recreational marijuana sales have reaped significant amounts of tax revenue that goes toward public services, schools, law enforcement, and road maintenance.
Despite these perceived benefits, the push for marijuana legalization may be unintentionally exposing the public to a significant risk of heart disease, neurological impairment, respiratory failure, stroke, and high blood pressure.
Balancing Medical Value With Medical Risk
How is marijuana used? The traditional method of consuming cannabis involves smoking the plant in a cigarette or pipe, but many marijuana users today consume edibles infused with cannabis, tinctures, beverages, and “dabs,” highly potent marijuana concentrates that appear like wax or glass. Marijuana is also becoming stronger than previously seen, with many new strains and designer hybrid plants eclipsing the potency of basic strains.
Smoking marijuana causes heart problems and interferes with respiratory functions, so this method may not work for every medical marijuana patient. Edibles can be profoundly potent and produce effects the average marijuana user may not expect. While some people may have a legitimate need to use medical cannabis, such as a condition that has not responded to conventional treatments or as a supportive measure for traditional treatment, these individuals must understand they are assuming a significant risk of developing long-term medical complications from cannabis use.
Marijuana’s Potential For Addiction
The negative effects of marijuana encompass far more than just physical health problems. Marijuana may not be as physically addictive as other drugs like meth and heroin, but cannabis can still be habit-forming and result in psychological dependency. A person who regularly consumes marijuana will need more to feel the desired effects. This tolerance eventually leads to dependency and potentially addiction.
