May I help the Minister and suggest that he speak with his colleague the Secretary of State for Health and ask about the extensive trial, known as delta-9, which took place in the Royal Marsden hospital 40 years ago? Cannabis was found to be an excellent prophylactic against nausea caused by ontological medicine. The data is there. The empirical evidence is there. Why does he not save time and trouble by having a word with the Secretary of State and drawing this information to the attention of the House? Let us resolve this matter once and for all.
