A Life of Its Own: The Truth About Medical Marijuana
Helen Kapalos (2016)
A Life of Its Own profiles the parents movement behind the 2016 Australian law allowing doctors to legally prescribe marijuana for their patients. The grassroots movement began with a policeman and his wife who obtained black market cannabis (on a doctor’s advice) to treat their son for severe side effects of cancer chemotherapy. It came to include dozens of other parents who had to break the law to treat children with intractable epilepsy and other severe disabilities.
Cannabis has been used to treat a variety of medical conditions for over 5,000 years. American doctors first used cannabis resin to treat children’s seizures in 1841. In the 1930s, shortly before the paper, plastics and petroleum industry conspired to have hemp (and cannabis) taxed out of existence (see The Politics of Hemp), US doctors wrote more than 3 million prescriptions for cannabis tincture for a variety of conditions.
There are few (roughly 100) randomized controlled trials of marijuana’s effectiveness as a medical treatment. This relates partly to strict laws in most countries prohibiting the cultivation of cannabis and partly to the unwillingness of the pharmaceutical industry to fund medical marijuana research.
I was very surprised to learn that most of this research occurs in Israel, funded by US foundations. The world pioneer of marijuana research is Raphael Mechoulom, professor of medicinal chemistry. Mechoulom, who first began studying the medical effects of cannabis in the 1960s, was the first to identify tetrahydrocannabinol (THC) and cannabidiol (CBD), its main therapeutic ingredients. In addition to identifying the presence of CBD1 receptors in the brain and CBD2 receptors in the immune system, he has also developed dozens of cannabis strains specific for different illnesses.
Israel has conducted the largest number of cannabis trials in the world, involving 20,000 patients at four hospitals. In addition to epilepsy, conditions studied include Parkinsonism, Tourette’s, multiple sclerosis, chronic pain, PTSD and terminal cancer.
