Exciting scientific evidence has been mounting over months and years on the efficacy of cannabis to treat different health conditions. These cannabis studies continue to unlock the medicinal benefits of the plant.

The cannabis plant yields therapeutic benefits because it contains a spectrum of cannabinoids, which stimulate the endocannabinoid system (ECS) in your body. This useful internal network helps regulate different bodily functions, including appetite, mood, sleep, pain, memory, and immune system response. CBD and THC are the main cannabinoids that can be activated from the plant, but other cannabinoids have beneficial effects too. And even terpenes found in cannabis have shown promising early results as a treatment against COVID-19 symptoms. 

Although cannabis hasn’t received the vigorous testing of other substances, some cannabis studies have demonstrated beneficial outcomes for patients. Here, we’ll look at the most definitive research currently available. 


Possibly the most compelling scientific evidence for the health benefits of cannabis comes from studies into symptom relief from severe epilepsy.  Nearly 7% to 20% of children have drug-resistant epilepsy. Through medicating with CBD, researchers have found a dramatic reduction in the number of seizures in sufferers of both Dravet syndrome and Lennox-Gastaut syndrome

Similar research and treatment development led the FDA to approve the use of Epidiolex, a medicinal oral CBD oil, in 2018.

Chronic Pain

Chronic (daily) pain affects more than 25 million adults in the US. 

A review of evidence in 2017 from the National Academies of Sciences, Engineering, and Medicine made nearly 100 conclusions related to the health benefits of cannabis and cannabinoid products. It found that treating adults with chronic pain with cannabis resulted in a clinically significant reduction in pain. 

CBD has also been found to inhibit inflammatory and neuropathic pain responses, which are both more tricky types of chronic pain to treat. 

Chemotherapy Symptoms

A few studies have found inhaling cannabis flower may be helpful for the relief of neuropathic pain, nausea and vomiting caused by cancer chemotherapy treatment.  

In another study, oral CBD treatments helped with nausea and vomiting, giving patients more than one option for how to consume cannabis. 

It’s important to note that most studies so far have been conducted in a laboratory, and few tested in real-world scenarios with cancer patients. This realm of cannabis’ benefits has great potential for more in-depth studies. 

Multiple Sclerosis Symptoms

A 2018 review of 17 clinical trials explored the use of cannabis for treating the symptoms of multiple sclerosis (MS). Their findings weren’t revolutionary but did suggest a notable benefit of cannabinoids for the treatment of spasticity, pain and bladder dysfunction in patients. 

When exploring the potential of cannabis for MS, researchers also tend to look at other cannabinoids besides THC and CBD. 

In particular, a 2010 study of 666 MS patients investigated the effects of Sativex, a spray containing the cannabinoid nabiximols. A significant number of patients achieved at least a 30% improvement in subjective spasticity when given the spray in addition to their usual medication. 

Cannabis Studies Guide Protocol

It’s essential that if you suffer from impaired health, present any cannabis product you want to take to your doctor first. Consulting with your physician will help you identify the best protocol to follow for a positive and therapeutic experience.

We’ve talked about only a few health conditions with the most encouraging evidence for the efficacy of cannabis. Many of the cannabis studies that have been conducted, along with plenty of anecdotal evidence, have shown this special plant has a wonderful capacity to offer a wide range of therapeutic benefits.
