Sarah Martin BBC Coverage On Legalising Cannabis For MS
There is a vigorous and articulate group around the legalization of cannabis in the UK .
Multiple sclerosis patient Sarah Martin believes cannabis is the best way to liberate herself from the daily pain she endures.
She says just half a teaspoon in a hot drink will keep her pain-free and spasm-free for about three hours. She also uses a vaporizer to ingest the drug.
But by obtaining the much sought after relief which enables her to walk a little more easily once her muscles have "freed up", she becomes a criminal.
She chooses not to take any regular - and legal - medication, maintaining it would give her side effects such as high blood pressure, ulcers and even the risk of heart failure and psychosis.
Professor Glynn Lewis, from the University of Bristol, said studies suggested that people who regularly smoke the drug double the risk of psychosis, although it is still uncommon - perhaps affecting 2 or 3% of users in their whole lifetime.
