Marijuana’s Impact on Mental Health: Balancing Benefits and Risks

Green waves of change sweep across America's legal landscape as marijuana's stigma slowly burns away. The past five years have witnessed a notable surge in the availability and acceptance of marijuana. As of now, 20 states in the United States have legalized marijuana for medical purposes, while eight states have approved its use for both medical and recreational purposes (NORML). Public opinion has shifted as well; 57% of American adults now support legalization, and a remarkable 69% believe that alcohol poses a greater threat to health than marijuana (Pew Research Center).

However, this increased interest in marijuana has sparked a significant debate, particularly concerning its impact on mental health. This essay aims to explore the complex relationship between marijuana use and mental health disorders, examining both the medicinal potential and the associated risks.

Medicinal Potential of Marijuana

Marijuana is composed of a wide variety of compounds, both psychoactive and non-psychoactive in nature. Researchers Fichtner and Howard have identified 483 compounds unique to marijuana, including the widely studied cannabidiol (CBD). These compounds have shown promise in treating various mental health disorders such as anxiety, depression, post-traumatic stress disorder (PTSD), and attention-deficit/hyperactivity disorder (ADHD). Patients have also turned to cannabis for relief from symptoms associated with bipolar disorder, chronic pain, insomnia, opiate dependence, and even schizophrenia. Furthermore, marijuana has demonstrated potential in alleviating symptoms of neurological conditions such as multiple sclerosis, dementia, and seizures, as well as reducing nausea and anorexia, particularly in cancer chemotherapy patients.

A 2017 article in Time Magazine by Sifferlin emphasized the potential benefits of cannabis for individuals dealing with depression, social anxiety, and PTSD. Notably, cannabis has shown great promise in replacing opioid medications for pain management, aiding individuals in reducing or discontinuing opioid use. This is especially significant given the ongoing opioid crisis. Despite marijuana's classification as a Schedule I drug due to its high potential for abuse, research continues to highlight its therapeutic potential. For instance, a 2015 study analyzed 79 different studies and found that cannabinoids provided a 30% or greater reduction in pain compared to a placebo (Whiting, Wolff, and Deshpande). Moreover, a 2014 study discovered that states with medical marijuana access experienced a 25% decrease in opioid overdose deaths (Bachhuber, Saloner, Cunningham, and Barry). THC, a key component of marijuana, has also been found to help alleviate opioid withdrawal symptoms, increasing the likelihood of successful detoxification (Fichtner and Howard).

The Double-Edged Sword: Risks and Concerns

Despite its potential benefits, marijuana use is not without its risks. Psychologists have long studied its influence on mood and behavior. While many individuals turn to cannabis to ease anxiety, calm nerves, and reduce impulsive and negative thoughts, some studies suggest that marijuana can be an alternative to traditional antidepressant medications by boosting mood and energy, enhancing appetite, and combating insomnia. Marijuana affects the brain by releasing neurotransmitters like dopamine and anandamide, which can contribute to decreased symptoms of depression and PTSD (Smith, M.).

However, a growing concern is whether individuals with mental illnesses are using cannabis to alleviate symptoms or if their mental health issues drive them to use marijuana. Researcher Lev-Ran's 2013 study revealed that individuals with mental illnesses are over seven times more likely to use cannabis weekly than those without such conditions. Moreover, individuals with depression are at a higher risk of initiating cannabis use compared to those without depression. While marijuana can offer relief, its anxiolytic and mood-enhancing effects can also heighten the desire and risk for depression and anxiety (Grunberg et al., 2015).

The negative consequences of marijuana use are not to be underestimated. Short-term effects include impaired memory, judgment, coordination, and balance, along with increased anxiety and paranoia (NIDA). Long-term users may face addiction, learning and memory impairments, potential IQ loss, an increased risk of chronic cough, and susceptibility to other substance use disorders, including alcohol. Of particular concern is the increased risk of schizophrenia associated with marijuana use (NIDA). A study conducted at St. Francis Xavier University found that Canadian adolescents, among the youngest and most frequent marijuana users in the developed world, exhibited more behavioral problems, including ADHD, defiant disorder, and conduct issues, rather than depressive symptoms (Thompson, Merrin, Ames, and Leadbeater). While cannabis does not appear to increase the risk of harm to oneself or others, it is often used as a coping mechanism for social problems (Walsh et al., 2017).

Finding Balance and Looking Ahead

Determining the relationship between marijuana and mental health is a complex task, as both benefits and harms are evident. Some associations vanish when other variables related to depression and marijuana use are considered (Grunberg et al., 2015). Differences in temperament and individual predispositions may influence the relationship between marijuana and depression. Some users prone to depression may experience benefits, while others may not. Factors such as the length of marijuana use, age of onset, frequency, dose, and duration, as well as pre-existing mental health conditions, play crucial roles in understanding the effects. Finding the right strain, dosage, and prescription can be as time-consuming as selecting an appropriate antidepressant or anti-anxiety medication (Lev).

Like all medications, marijuana has its benefits and side effects. Reducing the stigma surrounding marijuana use may encourage more individuals to explore its potential. However, further research is essential to better understand the complex relationship between marijuana and mental health. Future studies should consider variables such as gender differences, childhood trauma, age, and state legalization. Additionally, emotional sensitivity related to marijuana use should be explored. As marijuana becomes more accessible and accepted, it is crucial to consider the motivations for use, as well as the potential benefits and risks associated with its therapeutic application.

In conclusion, marijuana presents a multifaceted challenge in the realm of mental health. While it offers promise as a therapeutic tool, its potential risks cannot be ignored. Striking a balance between harnessing its benefits and mitigating its harms is essential. As research continues to evolve, a comprehensive understanding of marijuana's impact on mental health will guide informed decisions, ultimately improving the well-being of individuals seeking relief from various mental health disorders.
