Medical Marijuana: Uses, Functions, Side Effects, and Limitations

Introduction

Medical marijuana refers to the use of the cannabis plant or its chemicals to treat medical conditions. While it is still controversial in some countries, research has shown that marijuana may help manage symptoms of several chronic illnesses when used responsibly under medical guidance. This paper explores the causes for prescribing medical marijuana, its functions in treating diseases, methods of intake, side effects, and who should avoid using it.

Causes for Prescribing Medical Marijuana

Medical marijuana is usually prescribed by doctors when traditional treatments are not effective. Some of the common causes include:

• Chronic pain: Especially in conditions like arthritis, multiple sclerosis, or back pain.

• Cancer-related symptoms: It may reduce pain, nausea, and vomiting caused by chemotherapy.

• Epilepsy and seizures: Certain forms of epilepsy respond well to specific cannabis-based medicines.

• Glaucoma: Marijuana may help reduce pressure in the eye.

• HIV/AIDS: It can help increase appetite and reduce weight loss.

• Anxiety and PTSD: In some cases, it may be prescribed to reduce anxiety and improve sleep, although this depends on the individual.

• Muscle spasms: Especially those linked to multiple sclerosis or spinal cord injuries.

Doctors prescribe it only when they believe the potential benefits outweigh the risks.

Functions of Marijuana in Treating Severe Diseases

Marijuana contains active compounds called cannabinoids, the most common being THC (tetrahydrocannabinol) and CBD (cannabidiol). These affect the brain and body in different ways.

Functions include:

• Pain relief: THC interacts with parts of the brain and spinal cord to reduce pain signals.

• Anti-inflammatory effects: Useful in conditions like Crohn`s disease and rheumatoid arthritis.

• Controlling nausea and vomiting: Particularly effective for chemotherapy patients.

• Improving appetite: Helpful in patients with cancer or HIV/AIDS who struggle with weight loss.

• Reducing seizures: Especially in epilepsy patients where other treatments fail.

• Relaxation of muscles: Can reduce stiffness or spasms in neurological conditions.

These effects make marijuana a possible option for people with long-term, hard-to-treat conditions.

Ways to Take Medical Marijuana

There are several methods of consuming medical marijuana. The right method depends on the patient’s condition, age, and medical advice.

Common ways include:

1. Smoking: Quick effects, but may harm the lungs.

2. Vaporising: Heats marijuana to release active compounds without burning it, less harmful than smoking.

3. Edibles: Brownies, gummies, or drinks made with marijuana. Effects take longer to start (30–90 minutes) but last longer.

4. Tinctures and oils: Liquid extracts taken under the tongue for fast results.

5. Capsules or pills: Easy to take, with controlled doses.

6. Topical creams or gels: Applied on the skin to relieve local pain or inflammation.

Doctors recommend the safest method depending on the patient’s needs.
