And it is only likely to be prescribed for a small number of patients.
It is licensed in the UK for people with MS-related muscle spasticity that has not got better with other treatments.
Some products that might claim to be medical cannabis, such as “CBD oil” or hemp oil, are available to buy legally as food supplements from health stores. But there’s no guarantee these are of good quality or provide any health benefits.
How do I get a prescription?
It’s expected this would only apply to a very small number of people in England.
Very few people in England are likely to get a prescription for medical cannabis.
Nabiximols (Sativex) is a cannabis-based medicine that is sprayed into the mouth.
Some cannabis-based products are available to buy over the internet without a prescription.
This is not intended to be an inclusive list, but rather to give a brief survey of the types of conditions for which medical marijuana can provide relief. As with all remedies, claims of effectiveness should be critically evaluated and treated with caution.
Patients do, however, report many benefits of CBD, from relieving insomnia, anxiety, spasticity, and pain to treating potentially life-threatening conditions such as epilepsy. One particular form of childhood epilepsy called Dravet syndrome is almost impossible to control but responds dramatically to a CBD-dominant strain of marijuana called Charlotte’s Web. The videos of this are dramatic.
There are few subjects that can stir up stronger emotions among doctors, scientists, researchers, policy makers, and the public than medical marijuana. Is it safe? Should it be legal? Decriminalized? Has its effectiveness been proven? What conditions is it useful for? Is it addictive? How do we keep it out of the hands of teenagers? Is it really the “wonder drug” that people claim it is? Is medical marijuana just a ploy to legalize marijuana in general?
Uses of medical marijuana
My advice for patients is to be entirely open and honest with your physicians and to have high expectations of them. Tell them that you consider this to be part of your care and that you expect them to be educated about it, and to be able to at least point you in the direction of the information you need.
These are just a few of the excellent questions around this subject, questions that I am going to studiously avoid so we can focus on two specific areas: why do patients find it useful, and how can they discuss it with their doctor?
The most common use for medical marijuana in the United States is for pain control. While marijuana isn’t strong enough for severe pain (for example, post-surgical pain or a broken bone), it is quite effective for the chronic pain that plagues millions of Americans, especially as they age. Part of its allure is that it is clearly safer than opiates (it is impossible to overdose on and far less addictive) and it can take the place of NSAIDs such as Advil or Aleve, if people can’t take them due to problems with their kidneys or ulcers or GERD.
In particular, marijuana appears to ease the pain of multiple sclerosis, and nerve pain in general. This is an area where few other options exist, and those that do, such as Neurontin, Lyrica, or opiates are highly sedating. Patients claim that marijuana allows them to resume their previous activities without feeling completely out of it and disengaged.
The cannabidiol Epidiolex was approved in 2018 for treating seizures associated with two rare and severe forms of epilepsy, Lennox-Gastaut syndrome and Dravet syndrome. In addition, the FDA has approved two man-made cannabinoid medicines — dronabinol (Marinol, Syndros) and nabilone (Cesamet) — to treat nausea and vomiting from chemotherapy. The cannabidiol Epidiolex was approved in 2018 for treating seizures associated with two rare and severe forms of epilepsy, Lennox-Gastaut syndrome and Dravet syndrome.
