legalise cannabis in england

cannabis has been proven to prevent cancer, it has proven to cure many other health issues like Parkinson's and Huntington's disease or at least ease them ,,, it has healed and proven to cure depression and sleep disorders, and it would stop a lot of street crime and home crime and a lot of police time as a lot of police officers would have less crime to deal with and it would make the government a lot more money in taxes paid just like cigarettes or alcohol ,,, cannabis has never been proven of the death of any individual, alcohol kills many people every year, cigarettes kill many people a year they should both be illegal in the UK or at least England but they are not ,,,, cannabis helps, alcohol and cigarettes do not and I am a none smoker and a none drinker ,,, this is to help people not to get the average drug user there daily fix and would be cheaper for the government and I think that goes for the whole world, not just England
