In recent years, the conversation around marijuana use has intensified, especially as more regions consider legalising its use. However, new research highlights significant concerns about the effects of marijuana, particularly on sleep and memory, which are often overlooked in public discourse.

Marijuana and Sleep Disturbances

A recent study from the University of Texas at Dallas has unveiled that individuals with cannabis use disorder frequently experience poorer sleep quality. Dr. Francesca Filbey noted, “Sleep disruption from cannabis use isn’t necessarily insomnia-related or complete sleep deprivation; rather, it’s a reduction in the quality of sleep.” See more

This is a vital concern, as sleep is crucial for maintaining overall health and cognitive function. Poor sleep can lead to a range of issues, from reduced productivity to increased susceptibility to illnesses. Despite nearly half of users between ages 16 and 65 in the US and Canada reporting using cannabis to aid sleep, the research suggests that the drug may not provide the restorative sleep needed for optimal health. The findings suggest that marijuana use may exacerbate these problems, highlighting the need for awareness about its potential negative impact on sleep.

Memory Impairment and Cannabis

The research also indicates that marijuana use is linked to impaired visuospatial memory, which is the ability to retain and process information about objects’ appearance and location. Tracy Brown, a UT Dallas psychology PhD student, stated, “Although sleep is one of the primary reasons people use cannabis, our findings suggest that long-term cannabis use actually results in poorer sleep, which is associated with poorer memory.” See more

Notably, a 2016 study tracking over 3,000 middle-aged adults found that those who used marijuana for more than five years had worse verbal memory compared to less frequent users. This type of memory is essential for daily tasks, from navigating spaces to recognising faces. The impairments observed among regular users of marijuana may affect their everyday lives and could have long-term consequences if left unaddressed.

A Complex Interaction

The study points to the endocannabinoid system as a potential underlying mechanism impacting sleep and memory. This system, while naturally occurring in the body, is influenced by cannabinoids found in marijuana, potentially disrupting natural regulatory processes. Such disruptions may lead to altered circadian rhythms and impair the brain’s ability to consolidate new information into memories.

The Way Forward

As marijuana continues to gain acceptance, it is crucial to consider its potential risks. The findings from this study underscore the importance of further research to fully understand the long-term effects of marijuana on cognitive functions and overall health. By focusing on the negative impacts of marijuana use, we can better inform public policies and personal choices, prioritising health and well-being over recreational and medicinal use.

While the legal status of marijuana is evolving, it is essential to remain cautious and informed about its potential impacts on critical aspects of health such as sleep and memory. This understanding is crucial for making informed decisions that protect our long-term health and cognitive abilities.
