The largest ever health review on cannabis and its effects has concluded that young people, pregnant women, and drivers should avoid using the drug. The umbrella review, which analyzed data from more than 100 other studies, found that while cannabis-based medicines may be beneficial for certain medical conditions, the drug can be detrimental to the health of these specific groups.
The review highlighted the increased risk of poor mental health, car crashes, and negative outcomes for babies exposed to cannabis during pregnancy. However, the review also acknowledged the potential benefits of cannabis-based medicines for epilepsy patients, individuals with chronic pain, and those in palliative care. These findings emphasize the importance of understanding the potential risks and benefits associated with cannabis use among different populations.
Impact on Young People
Young people are at an increased risk of mental health issues due to cannabis use. The largest ever health review on cannabis and health found that cannabis use is linked to poor mental health and cognition. Most mental illnesses are first identified during teenage years and young adulthood, which coincides with a period when cognition is important for optimizing academic performance and learning. Therefore, it is recommended that young people avoid cannabis while their brains are still developing.
In addition to the increased risk of mental health issues, cannabis use also has negative effects on cognition in young people. The review of reviews analyzed data from 101 meta-analyses on cannabis use and found that taking the drug could be detrimental to cognitive function. This can have long-term implications for young people’s educational and career prospects.
Optimizing academic performance and learning is crucial for young people, and cannabis use can hinder these goals. Therefore, it is important for young people to avoid cannabis in order to maintain their cognitive abilities and achieve their academic potential.

Dangers for Drivers
Cannabis use poses dangers for drivers, including an increased risk of car crashes. The review of reviews found that cannabis use is linked to an increased risk of car crashes among drivers. Cannabis can impair cognitive and motor functions, making it dangerous to operate a vehicle while under the influence.
Not only does cannabis impair driving skills, but it also poses a risk to other road users. Impaired drivers are not only a danger to themselves but also to pedestrians, cyclists, and other motorists. Therefore, it is crucial for individuals to refrain from using cannabis before driving in order to ensure the safety of themselves and others on the road.
Positive Effects for Epilepsy Patients
Despite the potential risks and negative effects of cannabis use, there are positive effects for certain patient populations. One such population is epilepsy patients, who have been found to experience a reduction in seizures with the use of cannabidiol (CBD). CBD is a non-psychoactive compound found in cannabis that has shown promise in reducing seizure activity in epilepsy patients, particularly in children.
This finding is significant as epilepsy can be a debilitating condition that significantly affects an individual’s quality of life. The use of CBD as a treatment option provides hope for epilepsy patients who have not responded well to traditional pharmaceutical interventions.

Benefits for Multiple Sclerosis Patients
Cannabis-based medicines have been found to provide benefits for multiple sclerosis (MS) patients. MS is a chronic autoimmune disease that affects the central nervous system, leading to muscle spasms and other debilitating symptoms. The review of cannabis and health found that cannabis-based medicines can help reduce spasms in MS patients, providing relief from these symptoms.
In addition to reducing spasms, cannabis-based medicines have also been shown to improve the overall quality of life for MS patients. MS is a complex condition that can have profound physical and psychological effects on individuals. The use of cannabis-based medicines offers a promising alternative treatment option for MS patients, helping to manage their symptoms and improve their well-being.
Potential Benefits for Chronic Pain
Cannabis-based medicines have the potential to provide relief for individuals suffering from chronic pain. Chronic pain is a complex and multifaceted condition that can be difficult to treat effectively. The review of reviews found that cannabis-based medicines could help reduce chronic pain, offering a potential alternative to traditional pain management strategies.
Cannabis-based medicines work by interacting with the body’s endocannabinoid system, which plays a role in pain regulation. By targeting this system, cannabis-based medicines can help alleviate pain and improve the quality of life for individuals living with chronic pain.

Impact on Inflammatory Bowel Disease
Individuals with inflammatory bowel disease (IBD) may experience improvements in their symptoms and quality of life with the use of cannabis-based medicines. IBD, which includes conditions such as Crohn’s disease and ulcerative colitis, is characterized by chronic inflammation of the digestive tract.
The review of cannabis and health found that cannabis-based medicines can lead to improvements in symptoms such as abdominal pain, diarrhea, and reduced appetite. These improvements can have a significant impact on the quality of life for individuals with IBD, providing relief from the debilitating symptoms of the disease.
In addition to symptom improvement, cannabis-based medicines have also been shown to enhance the overall quality of life for individuals with IBD. Living with a chronic condition can take a toll on both physical and mental well-being, and the use of cannabis-based medicines can help individuals better manage their symptoms and achieve a better quality of life.
Role in Palliative Care
Cannabis-based medicines have been found to be effective in managing symptoms in palliative care settings. Palliative care focuses on providing relief from symptoms and improving the quality of life for individuals with serious illnesses. The review of cannabis and health found that cannabis-based medicines can help manage symptoms such as pain, nausea, and vomiting in palliative care patients.
By providing relief from these distressing symptoms, cannabis-based medicines can offer comfort and improve the overall well-being of individuals receiving palliative care. It is important to note that the use of cannabis-based medicines in palliative care should be done in consultation with healthcare professionals, as they can provide guidance on appropriate dosing and potential interactions with other medications.

Adverse Effects of Cannabis-based Medicines
While cannabis-based medicines can offer benefits for certain conditions, they are not without potential adverse events. The review of reviews found that cannabis-based medicines can have adverse effects, although the overall risk profile is generally considered to be relatively low.
Potential adverse events associated with cannabis-based medicines can include dizziness, drowsiness, dry mouth, and changes in appetite. These side effects are typically mild and manageable, but it is important for individuals using cannabis-based medicines to be aware of the potential risks and to consult with healthcare professionals for guidance and monitoring.
Under-recognized Source of Metal Exposure
Marijuana users have been found to have significant levels of metals in their blood and urine. A separate study analyzed the blood and urine of over 7,000 marijuana users and found that they had “significant levels” of metals such as lead and cadmium.
This finding suggests that marijuana use can be an under-recognized source of metal exposure, which can have detrimental effects on health. Metals such as lead and cadmium are known to be toxic and can accumulate in the body over time, leading to various health problems.
It is important for individuals using marijuana to be aware of this potential source of metal exposure and to take steps to minimize their risk. This can include using safer cultivation practices and purchasing cannabis products from reputable sources.
