Until today, there are still debates on the healing advantages of medical cannabis, making it a major issue in some countries. While several states have already legalized the use of marijuana, the federal authority continues to categorize it as a controlled material. Not only does it makes it unlawful to carry, but also restricts health studies into the promising benefits of marijuana.

With strong advocates on every side of the discussion, the debates for and in opposition to the legalization of cannabis are hot issues. What are the advantages and disadvantages of medical cannabis?


The legalization and use of cannabis for medical reasons are favored by many Americans, including members of the health society and Congress. Some of the claims for medical cannabis include:

• It can help treat anxiety and PTSD

The calming effects of cannabis are popular and it’s not shocking that the Clinical Psychology Review journal established that it may have advantages for patients with social fear, post-traumatic stress disorder, and depression. Also, research issued in the Drug and Alcohol Dependence discovered that a low dosage of THC which one of the main components of cannabis, can help individuals feel less anxious about speaking in public.

• It can alleviate nausea and chronic pain

The use of medical cannabis on pain alleviation is common and the National Academies of Sciences determined that there’s a good proof to support this practice. Cannabis products are also believed to help relax muscle contractions caused by sclerosis, alleviating nausea, and sickness due to chemotherapy.

They also concluded that there’s small evidence that marijuana-derived products may help treat individuals with sleeping disorders because of chronic pain, sleep apnea, and fibromyalgia.

• Patients especially kids with seizures may benefit

According to the study of the New England Journal of Medicine, cannabidiol oil has proven to reduced epilepsy by about 39% in kids with Dravet syndrome, a unique type of seizure. That was great news for patients who have been illegally using medical marijuana to help treat their kid’s incapacitating condition.

The oil that was used in the study was approved in 2018 by the FDA and sold as Epidiolex and what’s more benefitting is that it won’t make the user high since it doesn’t have THC. Experts claim that results may be more unpredictable and dangerous with other cannabis products.

• Safer Choice than Opioids

Several studies advocate that the use of health marijuana can decrease addiction on risky prescription painkillers such as those promoting the nation’s opioid outbreak.

In the study of Health Affairs in 2016, experts discovered that 1,826 were fewer daily amounts of painkillers given every year, on average in states where heath cannabis was legalized. Also, in the journal issued by Trends in Neuroscience, experts wrote that marijuana help individuals recuperate from opioid addiction. However, human trials were limited because the cannabis group is a Schedule 1 drug, and experts debate that more researches are needed.

• It may help treat cancer

The daughter of Olivia Newton-John recently revealed that the actress uses cannabidiol oil to battle her metastatic breast cancer. Studies have revealed that the oil can slow down the growth of the cancer cells outside the body, however, there was no real experiment to support the findings.

The assistant biology professor at Eckerd College named Gregory Gerdeman spoke to Time that there have been subjective patient reports and “growing numbers of legal medical case studies that all demonstrate cancer-fighting actions of cannabinoids”. It’s still undetermined but, whether the common type of cannabis would be an efficient cancer treatment or what types of cancer it might fight against.

• Cannabis has long been used as a natural therapeutic agent.

• Cannabis can alleviate the neuropathic pain some people are experiencing.

• As the study on marijuana continues, experts found that more of its compounds are found to be valuable. When it’s isolated like the CBD, these may result in a further breakthrough in the health treatment choices with experiencing the “high” that the THC compound gives.

• Findings show that smoking pot alone doesn’t increase the danger of lung diseases.

• Marijuana is beneficial in treating appetite loss related to ailments such as AIDS/HIV and other cancer types.

• Marijuana is still beneficial when taking it in other forms such as edibles, topical pain relief treatments, cannabidiol oils, and other non-burning methods.


For people who endorse cannabis legalization for health reasons, there are also those who are against it as well. The following are some of the claims from the rival:

• Marijuana is prohibited under federal law since it’s identified as a Schedule I drug in the CSA or the Controlled Substances Act together with the heroin. This group argues that substances like marijuana and heroin don’t have accepted medical value.

• Smoking, in general, can cause detrimentally injure your lung tissue.

• The regular smoking of marijuana can seriously damage your short-term memory.

• Marijuana can also ruin your mental skills.

• A user can abuse and become addicted to marijuana.

• The smoking pot contains cancer-producing substances.

• Marijuana has been found as the reason for the high percentage of work and vehicle accidents.

Scientific Support Are Still Limited

Long ago, medical experiments to examine the efficiency of cannabis to treat ailments and conditions have been limited. As health cannabis becomes more popular all over the world, experts are doing more researches and findings.

However, professional reviews of the latest research continue to encourage that more examinations are required. Many of the difficulties include regulating the quality and dosage of marijuana with what’s legitimately accessible to researchers. Also, several studies are not regulated medical experiments in which a sample or alternative treatment is used. Without these comparative studies, scientific documentation on the beneficial effects of marijuana will still be in question.

If we wanted a conclusive answer to whether cannabis is useful for symptom management, then it needs to be assessed using the same specifications as other treatments.

Final Thoughts

Medical marijuana is still under discussion but it’s gaining power as an effective treatment for a variety of conditions and ailments. Although, many states have already been using marijuana for medical purposes and some others for recreational use, it will take a long journey for the legislators and the U.S. government for it to become acceptable and lawfully sold all over the country.

In addition, this will require much substantial and genuine scientific research to verify or challenge the effectiveness of medical cannabis, and possibly unsnap the restrictions on its usage.
