Weed And Sleep: A Troubling First-Time Experience

Sleep disturbances are common among heavy marijuana users, and these issues can persist for months after quitting. According to a study by Johns Hopkins Medical Institutions, heavy marijuana users reported sleep disturbances such as strange dreams, insomnia, and poor sleep quality when abstaining from the drug. The study found that during the discontinuation of heavy marijuana use, polysomnographic measures of sleep disturbance were detected in users compared to a drug-free control group.

Another study found that adults who used marijuana 20 or more days a month were more likely to sleep less than six hours and more likely to sleep longer than nine hours a night. This may be because THC, the active component in marijuana, interferes with the release of melatonin, the hormone that makes us feel sleepy. As a result, people who smoke weed to sleep often wake up feeling groggy and disoriented.

Additionally, quitting marijuana can lead to withdrawal symptoms such as anxiety, irritability, and depression, which can further disrupt sleep. It is important to note that the effects of marijuana on sleep can vary from person to person, and more research is needed to fully understand the relationship between marijuana use and sleep disturbances.

Sleep disruption and REM sleep suppression

REM sleep, or rapid eye movement sleep, is a stage of sleep during which the eyes move rapidly in different directions, and the brain is active, similar to its activity during wakefulness. Dreams typically occur during this stage of sleep. While REM sleep is important for learning, memory, concentration, and mood regulation, it can also be disrupted by various factors.

Cannabis use, for example, has been found to impact sleep patterns and cognitive function even days after consumption. The main intoxicating component of cannabis, delta-9-tetrahydrocannabinol (THC), can induce impairment that may last well beyond the period of intoxication. While the duration of THC-induced impairment varies depending on factors such as dose, route of administration, and regularity of cannabis use, some studies suggest that the effects can persist for more than 24 hours. This has important implications for individuals who engage in safety-sensitive tasks, such as driving or operating heavy machinery.

The impact of cannabis use on sleep and REM sleep specifically is complex and multifaceted. On the one hand, cannabis is sometimes used to treat sleep disorders like insomnia. However, there is also evidence that THC can disrupt sleep patterns and impair cognitive function the day after use. This may be due to the way THC interacts with the endocannabinoid system, which plays a crucial role in regulating sleep and wakefulness.

Furthermore, the effects of cannabis use on sleep can vary depending on factors such as dose, frequency of use, and individual differences in physiology and metabolism. For example, occasional cannabis users may experience more impairment than regular users, who may develop a higher tolerance to the effects of THC over time. Additionally, the method of administration, such as smoking or oral ingestion, can also influence the duration and intensity of the effects.

While there is limited scientific evidence to support the assertion that cannabis use consistently impairs next-day performance, the potential risks associated with cannabis-induced sleep disruption and REM sleep suppression are significant. This is especially true for individuals who need to perform safety-sensitive tasks or make time-critical decisions. Therefore, it is essential to approach the use of cannabis with caution, particularly when it comes to activities that require alertness and unimpaired cognitive function.

Difficulty falling asleep and staying asleep

In addition, according to a study by Johns Hopkins Medical Institutions, heavy marijuana users showed differences in polysomnographic (PSG) measures compared to a drug-free control group. The marijuana users had lower total sleep times, worse sleep efficiency, longer sleep onset, and shorter REM latency than the control group. They also experienced more sleep disturbances on the second night of abstinence, indicating that sleep got relatively worse as the length of marijuana abstinence increased.

Furthermore, a study by BMJ Journals found that adults who used weed 20 or more days a month were 64% more likely to sleep less than six hours and 76% more likely to sleep longer than nine hours a night. This suggests that regular weed use can lead to irregular sleep patterns and disrupt the body's natural sleep cycle.

To improve sleep, it is recommended that people address any underlying mental health issues that may be preventing them from falling asleep. Practising good sleep hygiene, such as establishing a consistent sleep schedule, creating a relaxing bedtime routine, and limiting exposure to stressful content before bed, can also help. Seeking professional help from a doctor or a sleep specialist is advisable if sleep difficulties persist.

Worsening of underlying mental health conditions

While there is limited clinical evidence on the effects of weed on insomnia, it is known that weed can be used to treat insomnia and sleep disorders. However, weed can also be a cause of insomnia, especially for those with underlying mental health conditions.

Weed is often used to self-medicate for mental health issues, such as anxiety, stress, and ADHD. However, while weed may provide temporary relief, it can also worsen the underlying condition, leading to insomnia and other sleep issues. For example, weed can increase anxiety and cause "brain fog", making it difficult to fall and stay asleep. Additionally, the withdrawal effects of weed, such as increased anxiety and irritability, can also disrupt sleep.

In one study, individuals with mental health diagnoses, such as depression and anxiety, were more likely to report using weed to help them sleep. However, these individuals also experienced more sleep disturbances and lower sleep satisfaction after discontinuing weed use. This suggests that while weed may provide temporary relief, it does not address the underlying mental health issues and may even exacerbate them, leading to worsening sleep problems.

It is important to note that the relationship between weed and insomnia is complex and bidirectional. While weed can worsen mental health conditions, insomnia itself can also contribute to or worsen mental health issues. Therefore, it is crucial to address the underlying mental health issues rather than solely relying on weed as a short-term solution.

Furthermore, the effects of weed on sleep can vary depending on factors such as dosage, frequency of use, and individual differences. Higher doses of weed, particularly those with higher THC levels, have been associated with increased sleep disturbances. Additionally, regular and long-term weed users may develop a tolerance, leading to increased sleep latency and decreased slow-wave sleep.

In conclusion, while weed may provide temporary relief for mental health issues and insomnia, it is not a long-term solution. The worsening of underlying mental health conditions due to weed use can lead to insomnia and other sleep disturbances. Therefore, it is essential to seek professional help and explore alternative treatments, such as cognitive-behavioral therapy and medication, to address the root cause of the issue.

Development of dependence and addiction

The development of dependence and addiction to cannabis is a complex process that involves a range of biological, psychological, and environmental factors. While not everyone who uses cannabis will become addicted, it is possible to develop a cannabis use disorder, also known as marijuana use disorder. This disorder is characterised by a pattern of problematic cannabis use leading to clinically significant impairment or distress.

The risk of developing a cannabis use disorder is influenced by various factors, including the frequency and duration of cannabis use, age of first use, individual genetics and biology, and environmental factors such as peer influence and stress.

Biological Factors

The main psychoactive ingredient in cannabis, delta-9-tetrahydrocannabinol (THC), is responsible for its reinforcing properties and contributes to the development of addiction. THC stimulates neurons in the reward system of the brain to release dopamine, a neurotransmitter associated with pleasure and reward. Alterations in dopamine signalling are also seen with other addictive drugs.

Chronic cannabis use can lead to physiological changes in the brain, including adaptations in the endogenous cannabinoid system and other neurotransmitter systems. These changes may contribute to continued cannabis use and the development of dependence.

Psychological Factors

Psychological factors also play a role in the development of cannabis dependence and addiction. Mental health issues, such as anxiety, depression, or stress, can increase the risk of cannabis use as a coping mechanism. Additionally, individuals may use cannabis to self-medicate underlying mental health conditions, which can lead to the development of dependence.

Environmental Factors

Environmental factors, such as peer influence, social norms, and stress, can also contribute to the development of cannabis dependence and addiction. For example, individuals who are frequently exposed to cannabis use in their social circle or who experience high levels of stress may be more likely to initiate and continue cannabis use.

Treatment for Cannabis Dependence and Addiction

A range of behavioural and pharmacological treatments are available for cannabis dependence and addiction. Behavioural therapies, such as cognitive-behavioural therapy (CBT) and motivational enhancement therapy (MET), aim to address the underlying psychological factors contributing to cannabis use and provide individuals with strategies to manage cravings and avoid triggers.

Pharmacological treatments, such as oral THC and medications for sleep or co-occurring mental health disorders, may also be used to alleviate withdrawal symptoms and support recovery.

Prevention and Early Intervention

Prevention and early intervention strategies are crucial to reducing the development of cannabis dependence and addiction. Educational programmes, early intervention initiatives, and check-up interventions can help reach individuals who may be at risk of developing cannabis use disorders or who are ambivalent about seeking treatment.

In conclusion, the development of cannabis dependence and addiction is a multifaceted process influenced by biological, psychological, and environmental factors. Effective treatment and prevention strategies are available, and further research is needed to optimise outcomes and support individuals in their recovery journey.

Memory problems and difficulty concentrating

Marijuana's main psychoactive chemical, THC, affects memory formation by attaching to receptors in brain regions that are vital for memory formation, including the hippocampus, amygdala, and cerebral cortex. This results in short-term problems with thinking, working memory, executive function, and psychomotor function.

Research has shown that cannabis consumption can cause learning and memory problems that linger for weeks. Verbal learning, retention, and recall are especially affected for longer periods when the person is no longer high. Frequent cannabis use by teens may impact their memory and ability to concentrate. Young, frequent cannabis users have thinner temporal and frontal cortices, which help process memory functioning. Memory is critical for learning and study, but cannabis can also reduce motivation to learn, reducing a young person's engagement in education and their ability to perform.

While there is little doubt that some people who use cannabis experience impaired memory, establishing causation is tricky due to the potential impact of other drugs and the challenge of accurately recalling past drug use and associated problems. Recent research suggests that any memory impairment associated with cannabis use can be reversed when people stop using it, mainly in those who used cannabis at least once a week.

The effects of cannabis on memory may be influenced by the type of cannabis and the compounds it contains. Cannabis with higher levels of THC and lower or negligible amounts of CBD appears to have a more detrimental effect on short-term memory, particularly in adolescents. However, CBD has been found to interfere with the binding process of THC to cannabinoid receptors, dampening the feeling of euphoria.
