Medical cannabis is subject to laws relating to the growing, possession, transport, and use of marijuana. These vary from country to country and, in the United States, from state to state.

There are also differences between marijuana for general and recreational use and for the same product for medical use.

Of course, on Multiple Sclerosis News Today, we are only concerned with medical cannabis and its use by people with multiple sclerosis.

From the scientific point of view, the efficacy of marijuana or cannabis (the terms are interchangeable) in treating neurological problems, including multiple sclerosis, epilepsy, and movement problems, is not clear.

Studies of the efficacy of cannabis for treating multiple sclerosis have produced varying results. The combination of Δ9-tetrahydrocannabinol (THC) and cannabidiol (CBD) extracts give subjective relief of spasticity, though objective post-treatment assessments do not reveal significant changes.1

Evidence also suggests that oral cannabis extract is effective for reducing patient-centered measures of spasticity. A trial of cannabis is deemed to be a reasonable option if other treatments have not been effective.2 Its use for MS is approved in 10 countries.3 A 2012 review found no problems with tolerance, abuse or addiction.4

Medical Cannabis: A Complex Question

shutterstock_316097636The National Multiple Sclerosis Society in the US takes the view that the question of whether marijuana — produced from the flowering top of the hemp plant, cannabis Sativa — should be used for symptom management in MS is a complex one.

It says that there is general agreement that better therapies are needed for distressing symptoms of MS — including pain, tremor and spasticity — that may not be sufficiently relieved by available treatments. Still, there are uncertainties about the benefits of marijuana relative to its side effects.

The society supports the rights of people with MS to work with their MS healthcare providers to access marijuana for medical purposes in accordance with legal regulations where such use has been approved. In addition, the Society supports advancing research to better understand the benefits and potential risks of marijuana and its derivatives as a treatment for MS.

Across the Atlantic, in the UK, the situation is different. The MS Society says that People have claimed cannabis helps with some MS symptoms such as muscle spasms and stiffness as well as pain.

Surveys show significant numbers of people with MS in the UK use cannabis to manage their symptoms. Because medically tested cannabis-based treatments aren’t widely available, some people with MS obtain cannabis from other sources.

The difficulty in that country is that cannabis is a class-B controlled drug. That means that possessing, producing, and supplying it are all illegal. “Supply” includes sharing the drug with someone or giving it, even for free, to friends or relatives. The law doesn’t allow you to use as a defense the fact you were using cannabis for medical reasons.

However, the laws in some other European countries, notably the Netherlands and Spain, where I live, are much more liberal. In fact, Barcelona has been dubbed “the new Amsterdam” by some people.

There has been some research into using cannabis-based medicines for MS.

The Multiple Sclerosis Trust says that CAMS study, which involved 660 participants around the UK, looked at the effect of cannabis on various symptoms of MS, primarily on spasticity. Results of this study were mixed, with no significant effect on spasticity as measured by the Ashworth scale. However, some improvement was shown on the time taken to complete a 10-meter walk and patient satisfaction scores were positive.

Mixed Results in Trials

A systematic review published in December 2009 found that five out of six double-blind, randomized, controlled trials reported a decrease in spasticity and improved mobility in people with MS taking a combination of the cannabis extracts Δ9-tetrahydrocannabinol (THC) and cannabidiol (CBD). All of the studies reported some side effects which seemed to be related to the dosage. Generally, the treatment was well-tolerated.

The CUPID trial explored whether cannabis might have a role in protecting the brain from damage by multiple sclerosis, a concept called neuroprotection. The results from the study showed that there was no difference between participants who took the cannabis based medicine and those on placebo, with the treatment having no overall effect on the rate of progression.

However, the MUSEC trial, which was completed in 2012, involved 279 people taking a cannabis based pill or placebo. The trial showed higher proportions of people on the active treatment reporting reductions in muscle stiffness, spasms and pain, and improved sleep quality.

Sativex is a cannabis based mouth spray. It is licensed in the UK as an add-on treatment for moderate to severe MS spasticity in people who receive inadequate relief from the standard oral anti-spasticity medicines or have experienced unbearable side effects while taking these medicines. Although it is licensed throughout the UK, it is only available through the National Health Service in the constituent country of Wales.

Wherever it is legal to grow cannabis plants, suppliers of medical marijuana have appeared. I have even met a judge in Washington state, US, who is cultivating plants. These suppliers are openly advertising their wares online and through the social media.

I have talked to one such supplier, based in Ontario, Canada. He sent me details of his entire range of ‘pain-killer’ products including medical marijuana. It’s not cheap.

He told me: “We sell medical marijuana: One ounce for $230 (Canadian dollars), Quarter pound for $410, Half pound for $800, and One pound for $1,650.” The approximate metric equivalents are: 28gm, 113gm, 227gm and 454gm.

And those prices don’t include shipping.

Have I been tempted? No, not so far. But it all depends on how my symptoms develop in the future. Never say “never.”

Very informative article. Medical Cannabis may make people's lives better, but it isn't a cure. Cannabis is an adjunct whole health therapy that works in conjunction with other treats. Please continue to explore the subject of medical Cannabis and MS. Have a peaceful and productive day.

I live in Belgium, where Sativex has recently been approved for MS-patients; as I have noticed the benefits of (some strains of) cannabis before, I immediately asked my neurologist about it.

I had to go to the hospital for four weeks in observation to see if any benefits were measured.

I'm happy to say that the stuff works great as a pain- and spasticity reliever. There are slight side-effects, mainly dizziness, but they are way better than the side effects I had before, taking Clonazepam.

Talking to my peers, I must conclude that not everyone feels the same benefits as I do, but I do feel that it is worth a shot for everyone to try.

The on-set is very quick, and the effect remains for 4 to 8 hours. It has no long-term effect, I'm afraid. If I don't take it, I'll just revert back to my normal state of being: being in pain that is.

It helps for spasticity, restless limbs, pain-relief and improves sleep. The effect on the cognition is very minimal.

Hope you find this experience helpful.

Stay frosty :-)

I have had MS for 38 yrs. The 1st 15 yrs.,I was unaware of the fact that I had the disease. Then, in 1993, after some symptoms appeared, namely, some ataxia or foot drop of R. leg and weakness in R. hand and some bladder issues, the diagnosis was made @ age 52. I was shocked as there is no history of this disease anywhere in my family. I'm now 74 and in good health except for this damn disease. I can only take a few steps but can stand and transfer to things. I have used a bong @ 5 yrs. ago because a younger friend of mine was able to obtain the real stuff.I only smoked at night before bed and it relieved spasms and nerve pain which I had begun to experience. I had no side effects and was very pleased w/the results of eliminating leg spasms and nerve pain. It also helped me to sleep better. Sadly,I've needed the services of home health aides and they are forbidden by law in NY to light the bong:-( I recently have been approved for med. marijuana in tincture form so I will see how that goes. Don't expect any endorsement from the NMS Society as far as cannabis goes, as they are in bed, so to speak,w/Big Pharma.

I live in Ontario, Canada. The pricing you list for marijuana from your "Ontario contact" is insane - and it's probably street cannabis. Most people, like me, now get referrals to cannabinoid clinics so that we can get medicinal cannabis for our various health issues - for me it's fibromyalgia - for others, it's MS, colitis, crohn's, cancer, seizures, and the list goes on. It's been proven, scientifically, to help with symptoms and, in many cases, stave off or even cure. Pricing is not as high as you've been quoted so do not let that turn you off of trying something 'alternative' that will probably work.


The price quoted was from a cannabis producer who also operates a mail order business, although the price did not include shipping costs.

I get my CBD from

It comes in a seringue, it cost me less than $50/month. I take it twice a day, no more than the size of a grain of rice

Since it is CBD, it is legal pretty much anywhere and they ship worldwide.

You should give it a try Ian.

It's been demonstrated, experimentally, to help with indications and, by and large, fight off or even cure. Estimating is not as high as you've been cited so don't give that turn you a chance to off of taking a stab at something "elective" that will likely work.

Hi, I just want to ask if someone has any idea on which marijuana strain would be very effective when it comes with anxiety attacks and sleep disorder?
I've been suffering for almost 2 months now and mostly can't sleep properly at night. I refrain my self on taking meds coz it seems doesn't work for me. So I started reading some alternative way for my problem and came across this article about this strain from and how it could help you relax but the problem is I don't smoke. But then I also found out that you can also make drinks or tea and even muffin/cake as an option aside from smoking it. Why they can't just simply make a pill out of marijuana if they say it could really be some help? Or maybe there are that I'm not aware of. If this is true I would gladly want to hear any of your experience and thoughts regarding this. Thanks in advance

Purple indica strains are most calming and relaxing night time strains. My favorite is Grand Daddy Purple, but there are over 20 (Blackwater, Purple Urkle, etc)-and nearly everyone is an indica. You should feel the relaxation hit your body like a warm blanket rather quickly, especially if you're consuming edibles which provide more of a body high because of the "anthocyanins" that purple strains contain. I think you're narrowing into what you are looking for if you can obtain some purple and create an edible. Use Leafly. c om to research strains. Good luck.
