Experts say taking 300 milligrams a day by mouth for up to 6 months might be safe. Taking 1,500 milligrams per day by mouth for up to 1 month may be OK, too. People have used 2.5-milligram sprays under their tongue for up to 2 weeks.
More research is needed, but scientists think CBD may help with these MS symptoms:
How to Take CBD
Eating foods that are high in fat can cause your body to absorb more CBD. This can lead to side effects. It could react with other medications you’re taking, such as blood thinners. Be sure to talk to your doctor before trying any form of CBD.
FDA: “FDA Regulation of Cannabis and Cannabis-Derived Products, Including Cannabidiol (CBD).”
CBD oil is a common way to take it. You can put it under your tongue or add it to your food or drinks. You can also put it on your skin. Some research found sprays you put under your tongue might be best for MS.
Cannabis is made up of compounds called cannabinoids. The main ones studied for their therapeutic effect are tetrahydrocannabinol (THC), which gets you ‘high’, and cannabidiol (CBD), which doesn’t.
One in five people with multiple sclerosis (MS) surveyed in 2014 told us they’d used cannabis to help with their symptoms. They said it can help with muscle spasms or stiffness (spasticity) and pain.
There’s a medically approved cannabis-based treatment called Sativex, but it doesn’t work for everyone. In England, Wales and Northern Ireland it’s approved for use on the NHS for ‘moderate’ to ‘severe’ spasticity (muscle spasms and stiffness). But you can have it only if other treatments haven’t worked. It’s not yet approved in Scotland but we hope it soon will be.
In November 2018, the UK government legalised cannabis for medicinal use, but also put a strict criteria in place for who could access it. Only specialist doctors are allowed to prescribe medicinal cannabis, and so far only a handful of people have benefited from the change in law.
Some people with MS use cannabis in a variety of ways to help ease their symptoms.
