The use of marijuana as a medical treatment is becoming more widespread and has been legalized in 29 states plus the District of Columbia. However, there remains little scientific evidence about its effects on patients’ health.

This tension between people’s beliefs that it can be an effective cure for many ailments and the lack of knowledge around what effect this drug will have continues to grow with legalization spreading throughout the US, making it available both medically and recreationally.

Although many states across the US have legalized marijuana for medicinal purposes, there is still much debate about its safety and effectiveness. Scientific research has been conducted to establish whether or not medical cannabis can be used as a treatment without harmful side effects. Due to a lack of widespread studies, it’s difficult to determine how safe this drug really is.


Advantages Of Medical Marijuana?

Below are the findings of research that suggest marijuana may be beneficial in treating certain conditions.

The following were found to have benefits when using cannabis:

Chronic pain

The National Academies of Sciences, Engineering, and Medicine conducted a large review that assessed more than 10,000 scientific studies on the medical benefits and adverse effects of marijuana. They found evidence to support its use for chronic pain relief in adults.


Addictions to alcohol and drugs

In a review of the evidence published last year in Clinical Psychology Review, it was found that marijuana may help people with alcohol or opioid dependencies and can reduce their addictions. However, this study also suggests that those who use marijuana are more likely to abuse other substances. There is no “one size fits all” when it comes to addiction treatment approaches.

Depression, PTSD, and social anxiety are all symptoms of depression.

What is the purpose of marijuana? As it turns out, research has shown that some mental health conditions such as depression and post-traumatic stress disorder can be treated with this drug. However, other types of serious illnesses like bipolar disorders are not helped by using cannabis for treatment.


Research suggests that cannabinoids reduce nausea and vomiting caused by chemotherapy. Some small studies have found evidence to suggest smoked marijuana may also help alleviate these symptoms. Still, research on cancer cells reveals they are not effective at controlling or curing the disease in humans.

Few other diseases that can be believed to be treated by marijuana are Epilepsy and Multiple sclerosis.

Disadvantages Of Medical Marijuana?

Some studies have found that marijuana negatively affects physical and mental health. They are listed below:

The following negative associations were reported between smoking cannabis (marijuana) and human lung function or respiratory problems in different scientific papers:

Mental disorder

There is evidence that suggests among people with no history of the condition; there isn’t a link between marijuana use and developing bipolar disorder. Evidence shows regular users are more likely to experience suicidal thoughts and an increased risk for depression.

Despite the evidence that marijuana use increases the risk of psychosis, people with schizophrenia who have previously used marijuana have better memory and learning capabilities than those without a history of using it.

Respiratory Problems

A 2014 study found that while there was an association between smoking marijuana and an increased risk of lung cancer, it is unclear whether the two factors are directly related. In fact, researchers have had difficulty conclusively linking both conditions together because participants in studies often also use tobacco products when they smoke cannabis. It is possible that coughing could be caused by regular marijuana, but no evidence exists to suggest this right now.

Testicular cancer

There is no evidence to suggest any link between using marijuana and an increased risk for most cancers. However, the National Academies of Sciences did find some evidence that suggests a possible increased risk in one specific type of testicular cancer called seminoma subtype.

The Verdict

While some studies suggest marijuana can benefit people suffering from certain health conditions, other research suggests that the drug’s harmful effects outweigh its potential benefits. It is important to conduct more comprehensive and up-to-date reviews of both types of evidence to understand the public health implications of rising marijuana usefully.

While there is some evidence to support the use of marijuana, you should definitely be cautious if you have a history of mental health problems. It would help if you always spoke with your doctor before taking any new medicine.
