Medical marijuana: benefits, therapeutic uses, and scientific advances

Medicinal marijuana has gone from being a remedy used in pharmacies to spending decades as a prohibited substance surrounded by controversy. However, thanks to scientific progress and new analysis methods, we now have a much better understanding of its therapeutic properties and the enormous potential that cannabinoids have for treating various diseases.

Currently, medicinal cannabis is used to alleviate chronic pain, reduce muscle spasms, combat nausea, improve rest, and even as support in certain oncological treatments.

What is medicinal marijuana?

Medicinal marijuana refers to the therapeutic use of cannabis and its active compounds to treat specific symptoms or diseases. Unlike recreational use, the medicinal field seeks to utilize cannabinoids in a controlled and dosed manner.

Cannabinoids and their function

Since THC (tetrahydrocannabinol) was isolated in 1964, more than 100 cannabinoids present in the cannabis plant have been identified. Each one acts differently on the body.

The main ones are:

THC (Tetrahydrocannabinol)

It is the most well-known psychoactive cannabinoid. It can help to:

• Reduce pain.
• Stimulate appetite.
• Decrease nausea.
• Improve mood.
• Combat insomnia.

CBD (Cannabidiol)

It has no psychoactive effects and is one of the most widely used cannabinoids therapeutically.

Its most common applications include:

• Anxiety and stress.
• Inflammation.
• Epilepsy.
• Chronic pain.
• Muscle problems.

Other important cannabinoids

In addition to THC and CBD, there are other compounds such as:

• CBG
• CBN
• CBC
• THCV

Many of them continue to be studied for their potential medical application and their interaction with the endocannabinoid system.

How does cannabis act on the body?

The human body has a system known as the endocannabinoid system, which is responsible for regulating essential functions such as sleep, appetite, pain, mood, and the immune response. The cannabinoids present in cannabis interact with receptors distributed throughout the body and brain, helping to modulate different physiological processes and generating various therapeutic effects related to well-being and the body’s balance.

Action on the nervous system

Some cannabinoids present in medicinal cannabis have shown great therapeutic potential thanks to their interaction with the human body’s endocannabinoid system. Depending on their composition and concentration, they can help reduce intense pain, especially in patients with chronic diseases, as well as control muscle spasms associated with neurological conditions. They are also used to decrease nervousness, anxiety, and stress, promoting a sense of calm and well-being. Additionally, certain cannabinoids contribute to improving sleep quality and promoting rest, making them an increasingly studied alternative for people with insomnia or difficulty sleeping.

For this reason, medicinal cannabis is used for diseases such as:

• Fibromyalgia.
• Multiple sclerosis.
• Neuropathic pain.
• Chronic insomnia.

Action on the immune system

One of the areas that sparks the most scientific interest is the relationship between cannabinoids and the immune system.

Various studies are currently investigating the potential of cannabis to:

• Reduce inflammation.
• Modulate immune responses.
• Support oncological treatments.

Although there is still much to research, medical and scientific interest continues to grow.

Effects on mood

The psychoactive part of cannabis can also have therapeutic applications. In certain people, some cannabinoids can:

• Improve mood.
• Promote relaxation.
• Reduce anxiety.
• Stimulate creativity.
• Help to mentally disconnect.

This has opened new lines of research on mental health and emotional well-being.

Methods of consuming medicinal marijuana

For many years, smoking cannabis was the most common form of consumption. However, there are now much more precise and healthy methods.

Vaporizers: a more efficient alternative

Vaporization allows for the consumption of cannabinoids without combustion, considerably reducing the harmful effects of smoke.

Advantages of vaporizing cannabis

• Less lung irritation.
• Greater utilization of cannabinoids.
• Faster effects.
• Better dose control.

While smoking a joint utilizes approximately 20% of the cannabinoids, with a vaporizer, up to 90% absorption can be achieved.

Cannabis oils and extracts

Currently, cannabinoid-rich oils are one of the most used forms in therapeutic treatments.

Benefits of cannabis oils

• Precise dosing.
• Easy administration.
• Prolonged effects.
• Simple storage.
• Greater product stability.

Extracts can be mixed with olive oil or other vegetable oils and administered drop by drop according to the patient’s needs.

The importance of dosing in medicinal cannabis

One of the greatest advances in modern medicinal cannabis is the ability to precisely analyze the composition of each extraction. Thanks to laboratory analysis, it is now possible to know the exact amount of THC, the percentage of CBD, the terpene profile, and the presence of other minor cannabinoids in the product. This information allows for the development of much more precise, safe, and reproducible treatments, adjusting doses according to each patient’s needs and ensuring a more controlled and effective therapeutic experience.

Why is the quality of cannabis important?

The effects of medicinal cannabis can vary considerably depending on multiple factors, such as the genetics used, the part of the plant employed, cultivation conditions, the drying and curing process, as well as the extraction method used to obtain the cannabinoids. Each of these elements directly influences the concentration of active compounds such as THC, CBD, and terpenes, which are responsible for the therapeutic and aromatic effects of cannabis. Therefore, using analyzed and standardized products is essential to ensure consistent results, precise dosing, and a safer and more effective therapeutic experience for each patient.

Conclusion

Medicinal marijuana has evolved enormously in recent years thanks to scientific progress and the ability to analyze its compounds with precision.

Today we know that cannabinoids can have very broad therapeutic applications, from alleviating chronic pain to improving rest or reducing inflammation.

With proper regulation, analyzed products, and correct dosing, medicinal cannabis could become an increasingly important therapeutic tool in the future of medicine.
