Scientific studies on cannabis: here are the most curious ones

The most curious scientific studies on cannabis

Use of cannabis: studies that have found possible beneficial effects

The use of cannabis for medicinal purposes is a reality, although many studies have been conducted to ensure its effectiveness.

In this article, we look at some of the most curious and interesting scientific studies on the possible use of marijuana, both medically and otherwise.

Studies on cannabis as a treatment for multiple sclerosis

Various studies have been conducted on cannabis and legal cannabis in multiple forms to treat multiple sclerosis. Patients who volunteered to be investigated were given multiple forms of cannabis, such as cigarettes and capsules, while others were given the famous placebo, i.e., no medication at all.

These studies found little difference between those who ingested marijuana and those who simply believed it. However, it appears that when patients were asked to say how severe the pain was on a scale of 1 to 10, cannabis proved triumphant in reducing the pain.

Therefore, it is unclear whether cannabis could be an ally for such patients, and further research and investigation are needed.

Cannabis studies for Parkinson’s disease 

Studies have recently been conducted in the United States on how marijuana could benefit Parkinson’s disease, one of the worst neurodegenerative diseases that affects 1% of the population over 60.  

According to these studies, 44% of Americans with Parkinson’s disease and multiple sclerosis use marijuana. In addition, medical marijuana appears to have motor and other benefits, including.

  • decreased rigidity
  • decrease in bradykinesia
  • decreased tremors
  • pain relief
  • improved sleep quality

Thus, it is possible to infer that chronic use of marijuana may be functional for improving disease symptoms. Among other things, marijuana and legal cannabis could also be used to alleviate symptoms of depression in Parkinson’s patients.

On the other hand, the same study also reports some side effects of cannabis use, such as weight gain, memory loss and, contrary to what has just been said, depression.

Cannabis studies for cancer: paediatric oncology

Another interesting study conducted at the Centre for Child Health Research in 2021 investigates how cannabis can treat cancer.

It appears that cannabinoids may “have anti-cancer effects on certain types of cancer such as breast cancer, melanoma, pancreatic cancer, lymphoma, and brain cancer”.

Although much more data is available on the anti-cancer effects of cannabis in adults, very little is known about its effects on children. Most research has focused on leukaemia, and cannabinoids appear to kill leukaemia cells.

However, as suggested by the researcher, it is impossible to draw a firm conclusion about the effects of cannabis on cancer patients.

Hemp oil for cosmetics

Use of hemp oil for food and cosmetic purposes 

It appears that hemp oil (apart from CBD oil) can be used for food and cosmetic use due to a critical component known as terpenes.

Terpenes are biomolecules found in natural resins and essential oils that perform various functions, including protection from insects, herbivorous animals and high temperatures.

There are four primary terpenes found in cannabis:

  • Beta-caryophyllene, with anti-inflammatory and analgesic effects
  • Miocene, a molecule also found in hops and mango, is known for its relaxing and soothing properties.
  • Linalool, a molecule that benefits from the relaxing properties of Lavender
  • Limonene is a molecule in high concentrations in lemon and orange peel and is well known for its digestive and gastroprotective properties.

Another important component of cannabis is omega-3, which is used to produce ointments, oils, and creams. Hemp oil, therefore, seems to have proved a powerful ally not only for skincare, thanks to its moisturising, regenerating and antioxidant effects, but also for frizzy and damaged hair.

Studies conducted so far have not yet revealed any contraindications to the use of hemp oil but rather numerous benefits for both children and adults.

In conclusion, several studies were reviewed on the possible beneficial effects of cannabis, particularly for multiple sclerosis, Parkinson’s disease, cancer, and in cosmetics, body care and nutrition.

Cannabis has been shown to have potentially many benefits, but it still needs to be researched and studied further to ensure its efficacy and success.
