Drug research goes to pot

UK multiple sclerosis sufferers, and potentially those with rheumatoid arthritis, could soon be puffing on "cannabis" inhalers thanks to a government ruling. The British Home Office will allow the mouth spray drug, Sativex, to be imported for individual patients in exceptional cases, provided it is physician recommended. It is unclear how many of the estimated 85,000 MS patients in the UK might benefit from Sativex. Anecdotal evidence suggests, however, that some use more traditional forms of cannabis to relieve their symptoms.
