Cannabis and Mental Health: How Weed [Marijuana] Affects Your Mental Health?

Defining Cannabis, Weed, and Marijuana

For millennia, people have utilised cannabis, sometimes known as marijuana or pot, for its medicinal and intoxicating qualities. Although the cannabis plant contains more than 100 different types of cannabinoids, THC (tetrahydrocannabiol) and CBD (cannabidiol) are the two main ones of interest.

The primary psychoactive ingredient in marijuana that gives users a "high" is THC. It affects the brain regions responsible for pleasure, memory, thought, focus, movement, coordination, sensory perception, and time perception by attaching itself to cannabinoid receptors. Individual differences in THC effects can be attributed to a variety of factors, including dosage, mode of consumption, and physiological makeup (Hasan, 2023).

Conversely, non-psychoactive CBD has drawn interest due to its possible medicinal uses. CBD doesn't make you feel euphoric or intoxicated as THC does. Rather, it is being investigated for potential neuroprotective, analgesic, anti-inflammatory, and anti-anxiety effects. Compared to THC, CBD interacts with the body's endocannabinoid system differently, which could account for some of its varied potential effects.

Knowing the distinctions between these substances is essential to understanding the effects of marijuana on mental health. Although THC and CBD are frequently considered distinct substances, it's crucial to remember that the cannabis plant also includes other terpenes and cannabinoids in variable ratios that may also play a role in the plant's overall effects.

The Rise of Cannabis Use

In recent years, there has been a significant cultural and societal shift toward the increased use and acceptance of marijuana. As of 2024, recreational marijuana has been legalised in 24 American states, i.e., nearly half the country. Several factors have driven this change:

1. Legalization: Many countries and states have legalised cannabis for medicinal use, and some have also legalised it for recreational purposes. This legal shift has reduced stigma and increased accessibility.

2. Medical research: Growing evidence of potential medical benefits has led to increased interest in cannabis as a treatment for various conditions.

3. Changing public perception: As more information becomes available and societal attitudes evolve, the perception of cannabis has shifted from that of a dangerous drug to a more nuanced view that acknowledges both potential benefits and risks.

4. Economic factors: The cannabis industry has become a significant economic force, creating jobs and generating tax revenue in regions where it's legal.

5. Cultural representation: Marijuana use has become more prevalent in popular culture, including music, movies, and television, further normalising its use.

This article aims to explore the complex and multifaceted relationship between cannabis use and mental health, highlighting both potential benefits and risks. By examining current research, expert opinions, and real-world evidence, we seek to provide a balanced perspective on this important topic. Our goal is to offer readers a comprehensive understanding of how cannabis can affect mental health to provide context for making informed decisions about its use.

How Cannabis (Weed) Affects the Mind

Introduction to the Endocannabinoid System

The endocannabinoid system (ECS) is a complex cell-signalling system discovered in the early 1990s. It plays a crucial role in regulating a wide range of physiological and cognitive processes, including mood, memory, appetite, pain sensation, immune function, and more (Flygare & Sander, 2008).

Understanding the ECS is crucial for comprehending how cannabis affects mental health, as this system is deeply involved in regulating mood, stress response, and cognitive functions (Yarar, 2020).

Short-Term Effects on the Brain

Cognition and Perception

A 2019 study published in the American Journal of Drug and Alcohol Abuse found that acute cannabis use impaired verbal learning and memory by 11-12% and attention by 5-7%. These effects are primarily due to THC's interaction with the brain's cannabinoid receptors. 

Some of the key cognitive and perceptual changes include:

1. Altered time perception: Many users report that time seems to pass more slowly when under the influence of cannabis.

2. Impaired short-term memory: THC can interfere with the hippocampus, a brain region crucial for forming new memories.

3. Difficulty concentrating: Users often find it challenging to focus on complex tasks or maintain attention for extended periods.

4. Enhanced sensory perception: Colors may seem brighter, music more vivid, and textures more noticeable.

5. Impaired judgment: Cannabis use can affect decision-making abilities and risk assessment.

6. Reduced reaction time: This can be particularly dangerous when operating vehicles or machinery.

7. Creativity: Some users report enhanced creativity, though this effect is subjective and not consistently demonstrated in research.

These cognitive effects highlight the complex relationship between marijuana and mental health. While some users seek out these altered states for recreational or therapeutic purposes, they can also pose risks, especially in situations requiring clear thinking and quick reactions.

Mood and Behavior

Cannabis can have immediate and major effects on mood and behaviour, which contribute to its popularity as both a recreational substance and a potential therapeutic agent. However, these effects can vary widely:

1. Euphoria: Many users experience a sense of happiness, relaxation, and well-being, often described as feeling "high."

2. Anxiety and paranoia: Some individuals, especially those new to cannabis or using high-THC strains, may experience increased anxiety, paranoia, or panic attacks.

3. Sedation: Certain strains of cannabis, particularly those high in CBD or specific terpenes, can produce a calming, sedative effect.

4. Increased sociability: Some users report feeling more talkative and social, though this can vary depending on the individual and the social context.

5. Altered motivation: While using cannabis, some individuals may experience a decrease in motivation or ambition, often colloquially referred to as “amotivational syndrome."

6. Mood swings: Rapid mood changes can occur, especially as the effects of THC peak and then begin to wear off.

7. Increased appetite: Commonly known as "the munchies" cannabis often stimulates appetite, which can be beneficial for some medical conditions (such as cancer receiving chemotherapy but may be undesirable for others (Pietrangelo, 2023).

These mood and behavioural effects underscore why weed can be bad for your mental health in some individuals while potentially beneficial for others. The variability in these effects highlights the importance of considering individual factors, including mental health history and current psychological state, when using cannabis.

Long-Term Effects on Brain Development

Adolescent Brain Development

The impact of cannabis on the developing adolescent brain is a significant concern in the scientific community. The adolescent brain undergoes crucial developmental processes which continue into the mid-20s. Regular cannabis use during this period may interfere with these processes, potentially leading to long-term consequences:

1. Altered brain structure: Some studies have found differences in brain structure, particularly in areas rich in cannabinoid receptors, among adolescent cannabis users.

2. Impaired cognitive development: Regular use during adolescence has been associated with lower IQ scores and reduced cognitive function in adulthood (Waber et al., 2013).

3. Emotional regulation: Cannabis use may affect the development of brain regions involved in emotional regulation, potentially increasing vulnerability to mood disorders (Zehra et al., 2018).

4. Risk-taking behaviour: Adolescent cannabis use might influence the development of the prefrontal cortex, which is crucial for decision-making and impulse control (Romer, 2010).

5. Educational outcomes: Heavy cannabis use during adolescence has been linked to poorer educational outcomes, including increased dropout rates.

6. Increased risk of addiction: Early onset of cannabis use is associated with a higher risk of developing cannabis use disorder later in life.

These potential long-term effects of cannabinoids on development and behaviour underscore the importance of being mindful of cannabis use and preferably delaying it until adulthood when possible.

Potential Cognitive Decline

Chronic marijuana use has been associated with long-term cognitive effects, raising concerns about whether weed is bad for your brain over prolonged periods. 

Some of the potential areas of cognitive decline include:

1. Attention and concentration: Long-term users may experience difficulties in sustaining attention and concentrating on complex tasks.

2. Memory: Both short-term and long-term memory functions may be affected, with heavy users reporting difficulties in recalling information.

3. Processing speed: Some studies suggest that chronic cannabis use may slow cognitive processing speed.

4. Executive function: Functions such as planning, organizing, and problem-solving may be impacted by long-term use.

5. Verbal fluency: Research indicates a decrease in verbal fluency among long-term cannabis users.

6. Learning ability: The capacity to acquire and retain new information may be diminished with prolonged use.

It's important to note that the extent and reversibility of these cognitive effects can vary depending on factors such as the age of onset, duration, and frequency of use, and individual differences in brain physiology.

The Potential Benefits of Cannabis for Mental Health

Therapeutic Uses of Marijuana

Anxiety and Depression

Cannabis, particularly CBD, has shown promise in alleviating symptoms of anxiety and depression. 

Some potential benefits include:

1. Reduced anxiety: CBD has been shown to have anxiolytic properties, potentially helping with generalized anxiety disorder, social anxiety, and panic disorder.

2. Mood stabilization: Some users report improved mood and reduced symptoms of depression with cannabis use, though research in this area is ongoing.

3. PTSD symptom relief: Cannabis may help reduce hyperarousal, nightmares, and flashbacks associated with PTSD.

4. Social anxiety reduction: CBD, in particular, has shown potential in reducing social anxiety symptoms.

5. Stress reduction: Both THC and CBD may help in reducing stress levels, which can indirectly benefit those with anxiety and depression.

However, it's crucial to note that while these cannabis mental health benefits are promising, more research is needed to fully understand the long-term effects and optimal usage patterns.

Pain Management

One of the most widely recognized medical uses of cannabis is for pain management. This application can have significant implications for mental health, as chronic pain often co-occurs with mental health issues. 

Some key points include:

1. Neuropathic pain relief: Cannabis has shown effectiveness in managing neuropathic pain, which is often resistant to other treatments.

2. Reduction in opioid use: Some patients have been able to reduce their reliance on opioids by using cannabis for pain management, potentially reducing the risk of opioid addiction.

3. Improved quality of life: By alleviating chronic pain, cannabis can indirectly improve mood and mental well-being.

4. Fibromyalgia symptoms: Cannabis may help manage the pain and sleep disturbances associated with fibromyalgia. People suffering from fibromyalgia may experience pain, headaches, and nausea among other symptoms. Active ingredients of marijuana has shown to improve these symptoms.

5. Migraine relief: Some studies suggest that cannabis can reduce the frequency and intensity of migraines. A study by Cuttler et al., 2020 showed that administration of different strains and doses of cannabis led to a reduction in headaches in both men and women by approximately 50%.

6. Arthritis pain: Both THC and CBD have shown potential in managing arthritis pain and inflammation.

Stress Reduction and Relaxation

One of the most commonly reported effects of cannabis use is its ability to promote relaxation and reduce stress. 

This aspect of how cannabis helps mental health includes:

1. Muscle relaxation: Cannabis can help reduce physical tension, which often accompanies stress and anxiety.

2. Altered perspective: Some users report that cannabis helps them gain new perspectives on stressful situations, potentially reducing their impact.

3. Sleep aid: Cannabis, particularly strains high in CBD or certain terpenes, may improve sleep quality, which is crucial for stress management.

4. Mindfulness: Some users report that cannabis enhances their ability to be present at the moment, a key aspect of mindfulness practices.

5. Reduced rumination: Cannabis may help some individuals break cycles of negative thinking associated with stress and anxiety.

6. Social bonding: In some contexts, shared cannabis use can facilitate social connections, which can be beneficial for mental health.

However, it's important to note that while many users find cannabis helpful for stress reduction, overreliance on any substance for stress management can potentially lead to dependence issues.

The Potential Risks of Cannabis for Mental Health

Cannabis and Psychosis

Increased Risk of Psychosis

The link between cannabis use and an increased risk of psychosis is one of the most significant concerns regarding why weed can be bad for your mental health. A 2022 study published in Psychological Medicine showed that daily cannabis use was associated with nearly four times the odds of psychotic disorder compared with never users.

Key points include:

1. Genetic predisposition: Individuals with a family history of psychotic disorders may be at higher risk when using cannabis.

2. Age of onset: Early and frequent cannabis use during adolescence is associated with a higher risk of developing psychotic symptoms.

3. THC content: High-potency cannabis (with high THC levels) seems to carry a greater risk than lower-potency varieties.

4. Frequency of use: Daily or near-daily use of cannabis is associated with a higher risk of psychosis than occasional use.

5. Triggering latent conditions: Cannabis use may trigger the onset of psychotic disorders in individuals who are predisposed but might not have otherwise developed symptoms.

6. Worsening of existing symptoms: For individuals with psychotic disorders, cannabis use can worsen symptoms and interfere with treatment.

7. Neurochemical changes: THC's interaction with the endocannabinoid system may lead to changes in neurotransmitter systems implicated in psychosis.

Cannabis and Mood Disorders

Bipolar Disorder and Anxiety

The relationship between marijuana and mood disorders is complex and often contradictory. While some individuals report benefits, others experience amplification of symptoms. Here's a brief look at how cannabis interacts with bipolar disorder and anxiety:

Cannabis use in individuals with bipolar disorder and anxiety presents a complex picture with varied effects. For those with bipolar disorder, cannabis may influence mood cycling, potentially triggering or exacerbating manic episodes, and affecting depressive symptoms. It can also interact with bipolar medications and complicate treatment due to self-medication practices. In the context of anxiety, cannabis exhibits paradoxical effects: while some users report relief, others experience increased anxiety, especially with high-THC strains. CBD shows promise in reducing social anxiety, but THC may heighten it. High doses of THC can trigger panic attacks in susceptible individuals, and chronic use may alter the brain's stress response system. Additionally, regular users may face increased anxiety during withdrawal. The variability in these effects highlights the importance of individual assessment and careful monitoring when considering cannabis use for mood disorders, emphasizing the complex relationship between cannabis and mental health 

Bipolar Disorder:

1. Mood cycling: Some studies suggest that cannabis use may increase the frequency of mood episodes in bipolar disorder.

2. Manic episodes: THC may trigger or worsen manic episodes in some individuals with bipolar disorder.

3. Depressive symptoms: While some users report relief from depressive symptoms, others experience worsening depression with long-term use.

4. Medication interactions: Cannabis may interact with medications commonly prescribed for bipolar disorder, potentially reducing their effectiveness.

5. Self-medication: Some individuals with bipolar disorder may use cannabis to manage symptoms, which can complicate diagnosis and treatment.

Anxiety:

1. Paradoxical effects: While many users report anxiety relief, others experience increased anxiety, especially with high-THC strains.

2. Social anxiety: CBD has shown promise in reducing social anxiety, but THC may increase it in some users.

3. Panic attacks: High doses of THC can trigger panic attacks in susceptible individuals.

4. Long-term effects: Chronic cannabis use may alter the brain's stress response system, potentially affecting anxiety levels over time.

5. Withdrawal: Regular users may experience increased anxiety when attempting to quit or reduce use.

Understanding this variability is key to comprehending weed and mental health dynamics. It underscores the importance of individual assessment and careful monitoring when considering cannabis use for mood disorders.

Addiction and Dependence

Cannabis Use Disorder

Cannabis Use Disorder (CUD) is a recognized condition in the DSM-5, characterized by problematic patterns of cannabis use leading to clinically significant impairment or distress. 

Key characteristics of CUD include:

1. Prevalence: Approximately 10% of cannabis users develop CUD, with higher rates among those who start using in adolescence.

2. Diagnostic criteria: CUD is diagnosed when an individual exhibits at least two of eleven criteria, including using larger amounts over time, unsuccessful attempts to quit, and continued use despite physical or psychological problems.

3. Tolerance: Regular users may develop tolerance, requiring more cannabis to achieve the desired effect.

4. Withdrawal: Symptoms can include irritability, sleep difficulties, decreased appetite, and mood changes.

5. Craving: Strong desires or urges to use cannabis, often triggered by environmental cues.

6. Impact on daily life: CUD can lead to significant impairment in social, occupational, or academic functioning.

7. Quitting weed depression: Many individuals experience depressive symptoms when trying to quit, which can complicate recovery efforts.

8. Cognitive impact: Long-term, heavy use associated with CUD may lead to cognitive deficits, particularly in attention and memory.

9. Treatment options: Various approaches, including cognitive-behavioral therapy, motivational enhancement therapy, and in some cases, medication-assisted treatment, can be effective in managing CUD.

10. Comorbidity: CUD often co-occurs with other mental health disorders, complicating diagnosis and treatment. Common examples include depression, bipolar disorder, attention-deficit hyperactivity disorder (ADHD), psychotic illness, borderline personality disorder, and anti-social personality disorder (Common Comorbidities With Substance Use Disorders Research Report, 2020).

Understanding CUD is crucial for addressing the addictive potential of marijuana and developing effective interventions for those struggling with problematic use.

Physical and Mental Health Risks

Respiratory and Cardiovascular Issues
