How Does Marijuana Affect Mental Health?

The Impact of Cannabis Use

Cannabis use can have significant implications for mental health, particularly concerning cognitive function and overall brain health. Understanding these effects is essential for individuals struggling with substance abuse.

Cognitive Deficits and Hippocampal Volume

Long-term use of cannabis has been linked to cognitive deficits and decreases in hippocampal volume, especially during midlife. Research indicates that there are dose-response associations; meaning, the more cannabis is used over time, the greater the cognitive impact [1].

The table below highlights some of the cognitive effects associated with long-term cannabis use:

• Learning: Impaired

• Memory: Decreased efficiency

• Processing Speed: Slower

• Attention: Reduced

• IQ: Decline of 5.5 points (average from childhood)

As these effects indicate, ongoing cannabis use may hinder learning abilities and cognitive performance over time.

Midlife Cognition Effects

Heavy cannabis use can particularly affect cognitive performance during midlife. Studies have shown that individuals who heavily used cannabis may struggle with attention, memory, and processing speed [2]. It's worth noting that while some individuals with a history of cannabis use and psychotic disorders have shown better cognitive performance in areas like verbal learning and memory, this is not the case for all users.

The effects of cannabis on cognitive abilities, particularly in midlife, underscore why it is crucial for individuals struggling with addiction to seek support.

Anxiety and Cannabis

Cannabis is often discussed concerning its effects on mental health, especially anxiety. Many individuals facing anxiety seek relief through different methods, and cannabis has gained significant attention in this regard.

Perceived Health Benefits

A national survey conducted in 2017 revealed that 81 percent of Americans believed cannabis had one or more health benefits. Almost half of those surveyed specifically mentioned “anxiety, stress, and depression relief” as potential advantages of using cannabis. This perception leads many to consider cannabis as an option for managing their anxiety symptoms.

Many individuals report that, when used appropriately, cannabis can provide temporary relief from anxiety. However, experiences can vary significantly among users. For some, cannabis may help reduce anxiety, while others may find that it exacerbates their symptoms. Below is a table summarizing common perceptions of cannabis use for anxiety:

• Believed in health benefits: 81%

• Listed anxiety relief: 50%

CBD and Anxiety Treatment

Cannabidiol (CBD), a compound found in cannabis, has shown promise as a treatment for anxiety. A review conducted in 2015 suggests that CBD could be particularly helpful for social anxiety. Research has indicated that low doses of tetrahydrocannabinol (THC) may also assist in reducing overall anxiety levels and distress, potentially decreasing the frequency of panic attacks.

However, caution is advised when using cannabis for anxiety management. While low doses may provide relief, high levels of THC can lead to elevated anxiety symptoms, including rapid heartbeat and racing thoughts. To help mitigate these effects, individuals are encouraged to use cannabis cautiously and start with smaller doses.

Additionally, CBD has demonstrated the capability to reduce inflammation and neuropathic pain, highlighting its potential health benefits. As with any treatment, it is essential for those considering cannabis for anxiety to consult healthcare professionals and explore all available options.

Cannabis Use and Mental Health

Cannabis has been a topic of discussion when it comes to its effects on mental health, especially concerning severe conditions like schizophrenia and bipolar disorder. Understanding these relationships is crucial for individuals dealing with addiction and their mental well-being.

Schizophrenia and Psychotic Disorders

Research indicates a strong association between cannabis use and the development of schizophrenia and other psychotic disorders. Studies have found that individuals who frequently use cannabis may face a higher risk of psychotic outcomes, with an adjusted odds ratio of 2.09 for those who have used cannabis regularly [3].

• Any Use: 1.41

• Frequent Use: 2.09

• Severe Use: 3.9

A systematic review revealed an odds ratio of 3.9 for the association between cannabis use and psychosis among the most frequent users NCBI Bookshelf. This suggests that more frequent consumers are at a significantly high risk of developing schizophrenia or other psychotic disorders.

Several studies demonstrate that individuals with schizophrenia spectrum disorders show a higher prevalence of cannabis use compared to the general population. The connection between cannabis and these disorders indicates a dose-dependent relationship, which may be influenced by genetic factors.

Cannabis use is linked to an increased risk of developing psychosis, especially in individuals who are already at ultra-high risk for psychotic disorders.

Bipolar Disorder and Cannabis

The relationship between cannabis use and bipolar disorder is also a concern. While some individuals with bipolar disorder may use cannabis as a form of self-medication, there are significant risks. Cannabis might exacerbate mood episodes in those diagnosed with bipolar disorder and could lead to a cycle of use and relapse.

Longitudinal studies have shown that individuals with bipolar disorder might experience worse outcomes in terms of mood stability when engaging in cannabis use. It's crucial for those struggling with this condition to be aware of how marijuana may affect their mental health and overall stability.

The best approach for someone with bipolar disorder considering cannabis is to discuss this with a healthcare professional, who can provide tailored advice based on their specific situation. Understanding the effects of marijuana on mental health, including potential exacerbation of bipolar symptoms, is vital for managing recovery and maintaining well-being.

In summary, both schizophrenia and bipolar disorder present serious implications when associated with cannabis use. Individuals facing these challenges must navigate their relationship with marijuana carefully, ideally with guidance from mental health professionals.

Cannabis Effects on Psychosis

The effects of marijuana on mental health extend to serious conditions such as psychosis. Understanding these effects is vital for individuals facing challenges related to substance use.

Development of Psychotic Outcomes

Research indicates a significant association between cannabis use and the risk of developing psychotic disorders, including schizophrenia. A systematic review revealed that the odds ratio for this association is as high as 3.9 among the most frequent cannabis users, illustrating a heightened risk for those who consume marijuana regularly.

The following table summarizes the associations between cannabis use and the development of psychosis:

• Any use: Adjusted Odds Ratio for Psychosis = 1.41

• Frequent use: Adjusted Odds Ratio for Psychosis = 2.09

The increased risk is particularly concerning for individuals with a history of cannabis use. Longitudinal studies suggest that the likelihood of transitioning to psychosis rises notably for those who are at ultra-high risk for developing such disorders. Daily use of cannabis among patients with first-episode psychosis has been linked to a higher probability of developing these severe mental health issues [3].

Cognitive Function in Psychotic Disorders

Interesting findings also emerge from studies regarding cognitive performance in individuals with psychotic disorders. Evidence suggests that a history of cannabis use may be linked to improved performance in certain cognitive areas compared to those who have never used cannabis.

This relationship indicates that while cannabis has well-documented risks regarding psychosis, it may also have nuanced effects on cognitive function.

This complexity emphasizes the importance of evaluating both the risks and benefits of cannabis use, especially for individuals dealing with mental health challenges. The potential implications for cognitive improvement should not be overlooked, but the associated risks of developing serious mental health conditions warrant serious consideration.

Cannabis Use Disorders

Understanding cannabis use disorders is essential for recognizing the broader impact of marijuana on mental health. These disorders can manifest as dependence and addiction, which can significantly affect an individual's life.

Dependence and Addiction

About one in ten regular cannabis users become dependent on it. The risk of developing an addiction is higher among individuals who start using cannabis in their teens or who use it daily Rethink Mental Illness. Dependence can lead to tolerance, meaning that greater amounts of cannabis are needed to achieve the same effects over time.

Individuals experiencing cannabis use disorder may find it challenging to stop using, despite negative consequences in their personal and professional lives. They may prioritize cannabis use over other important activities and responsibilities, further contributing to their addiction.

• Regular Users: 10%

• Teen Users: Higher than 10%

• Daily Users: Even higher

Withdrawal Symptoms

Some heavy cannabis users may experience withdrawal symptoms when stopping or significantly reducing their cannabis intake, even if they do not have cannabis use disorder. The withdrawal symptoms can include:

• Anger

• Irritability

• Anxiety

• Restlessness

• Decreased appetite

• Depression

• Insomnia

• Headaches

• Tremors

These symptoms can make it difficult for individuals to quit or cut back on their cannabis use, leading to a cycle of continued use despite a desire to stop.

Learning to cope with withdrawal symptoms is crucial for recovery. Those struggling with cannabis use may benefit from support systems and guidance, including recognizing the signs of a substance use disorder and finding effective strategies for overcoming relapse: getting back on track.

Self-Medication and Anxiety

Anxiety and Cannabis Use

Many individuals experiencing anxiety may turn to cannabis in search of relief. Research indicates a positive association between anxiety and cannabis use, with studies showing an odds ratio of 1.24 for general cannabis use and even higher at 1.68 for cannabis use disorder (CUD) PMC. This suggests that those suffering from anxiety might be more likely to engage in cannabis use.

For individuals with cannabis use disorder, there is a notable correlation with anxiety disorders, including generalized anxiety disorder, panic disorder, or post-traumatic stress disorder (PTSD). This trend highlights a pattern of self-medication among those who may find temporary relief from anxiety symptoms through cannabis use.

• Cannabis Use: Odds Ratio (OR) 1.24, Confidence Interval (CI) 1.06–1.45, Studies Involved: 15

• Cannabis Use Disorder: Odds Ratio (OR) 1.68, Confidence Interval (CI) 1.23–2.31, Studies Involved: 13

Self-Medication Hypothesis

The self-medication hypothesis is the leading theory to explain the relationship between cannabis use and anxiety disorders. According to recent PATH analysis, this model suggests that individuals may use cannabis as a way to alleviate anxiety symptoms rather than cannabis causing these symptoms directly PMC. Causal interpretations of cannabis use leading to anxiety disorders are considered less plausible.

The most compelling evidence supports that anxiety predisposes people to use cannabis to self-medicate. This hypothesis indicates that individuals exhibiting anxiety symptoms are more likely to seek out cannabis as a coping mechanism. The presence of anxiety symptoms often precedes cannabis use, further suggesting a self-medicating behavior rather than a direct causative relationship.

Understanding this dynamic can be crucial for those dealing with anxiety and cannabis use.
