Multiple sclerosis is a chronic inflammatory disease of the central nervous system that affects over two million people worldwide. Patients may suffer from a wide range of disabling complaints which are not always easy to treat. Although cannabis is best known as a psychoactive recreational drug, it is also increasingly associated with a variety of positive medical effects.

Multiple sclerosis is the commonest neurological disease  affecting young adults. In patients under 30,  treatment needs to be adjusted accordingly.
