The Home Office has licensed GW Pharmaceuticals to grow thousands of potent cannabis plants for research. About two dozen patients are expected to take part in an initial trial which will test tolerability and dose levels. The research is aimed mainly at investigating the potential of cannabis to relieve pain and muscle spasms. Patients in the pilot study are likely to suffer from multiple sclerosis, spinal injuries and the "phantom limb" pain that often follows amputation. Seeding is about to begin at a UKP4 million greenhouse complex in the South of England. The Home Office and Special Branch advised on security for the secret site with up to 20,000 cannabis plants. The patients will be taking an extract of whole cannabis - not isolated chemicals - and will take in its vapour through inhalers. Geoffrey Guy, founder and chairman of GW Pharmaceuticals, said: "Inhaling allows more rapid absorption of the plant compounds than taking cannabis orally." Dr Guy, who gave evidence yesterday to the House of Lords Science and Technology Select Committee, said that the trial patients would not be getting "high" on cannabis. The amount of the drug needed to relieve pain or prevent muscle spasms was below this level. When people experienced a "high" from cannabis they were, in effect, taking an overdose, he said. He expected a "flood" of patients volunteering to take part in the trials. Some would already have experience of cannabis while others would be taking the drug for the first time. A recent survey by Disability Now magazine showed that almost 98 per cent of its readers supported the legalisation of cannabis, and 67 per cent said that they had taken cannabis for medicinal reasons. - ---
