All these effects are dose-related and the potency of cannabis preparations have increased tenfold over the past decade. I and others presented the evidence for these effects both orally and in writing to the House of Lords Select Committee in 1998, and to the Home Affairs Drugs Inquiry Committee in 2001. We also wrote a comprehensive report on cannabis as requested by the Department of Health, and one for the Ministry of Defence. All this information seems to have been ignored by politicians. I have spoken about cannabis to MPs and been amazed by their ignorance, despite the information available to them; they do not seem to read it or heed it.
