MEDICAL BENEFITS OF MARIJUANA

Some studies have shown that cannabidiol (CBD), another major marijuana compound, seems to help people with treatment-resistant epilepsy.

A number of individuals have reported that marijuana is the only thing that helps control their or their children’s seizures.

However, there haven’t been many gold-standard, double-blind studies on the topic, so researchers say more data is needed before we know how effective marijuana is.

It also decreases the symptoms of a severe seizure disorder known as Dravet’s Syndrome.

During the research for his documentary “Weed,” Sanjay Gupta interviewed the Figi family, who treated their 5-year-old daughter using a medical marijuana strain high in cannabidiol and low in THC.

The Figi family’s daughter, Charlotte, has Dravet Syndrome, which causes seizures and severe developmental delays.

According to the film, the drug decreased her seizures from 300 a week to just one every seven days. Forty other children in the state were using the same strain of marijuana to treat their seizures when the film was made — and it seemed to be working.

The doctors who recommended this treatment said the cannabidiol in the plant interacts with brain cells to quiet the excessive activity in the brain that causes these seizures.

Gupta notes, however, that a Florida hospital that specializes in the disorder, the American Academy of Pediatrics, and the Drug Enforcement agency don’t endorse marijuana as a treatment for Dravet or other seizure disorders.

A chemical found in marijuana stops cancer from spreading, at least in cell cultures.

CBD may help prevent cancer from spreading, researchers at California Pacific Medical Center in San Francisco reported in 2007.

Other very preliminary studies on aggressive brain tumors in mice or cell cultures have shown that THC and CBD can slow or shrink tumors at the right dose, which is a strong reason to do more research.

One 2014 study found that marijuana can significantly slow the growth of the type of brain tumor associated with 80% of malignant brain cancer in people.

Still, these findings in cell cultures and animals don’t necessarily mean the effect will translate to people — far more investigation is needed.

It may decrease anxiety in low doses.

Researchers know that many cannabis users consume marijuana to relax, but also that many people say smoking too much can cause anxiety. So scientists conducted a study to find the “Goldilocks” zone: the right amount of marijuana to calm people.

According to Emma Childs, an associate professor of psychiatry at the University of Illinois at Chicago and an author of the study, “we found that THC at low doses reduced stress, while higher doses had the opposite effect.”

A few puffs was enough to help study participants relax, but a few puffs more started to amp up anxiety. However, people may react differently in different situations.

It seems to lessen side effects from treating hepatitis C and increase treatment effectiveness.

Treatment for hepatitis C infection is harsh: negative side effects include fatigue, nausea, muscle aches, loss of appetite, and depression. Those side effects can last for months, and lead many people to stop their treatment course early.

But a 2006 study in the European Journal of Gastroenterology and Hepatology found that 86% of patients using marijuana successfully completed their Hep C therapy. Only 29% of non-smokers completed their treatment, possibly because the marijuana helps lessen the treatment’s side effects.

Marijuana also seems to improve the treatment’s effectiveness: 54% of hep C patients smoking marijuana got their viral levels low and kept them low, in comparison to only 8% of nonsmokers.

Marijuana users tend to be less obese and have a better response to eating sugar.
