Freedom. Freedom! FREEDOM!!!!
The use, possession and supply of all drugs should be legalized immediately. It will destroy organized crime cartels, solve the problem of overpopulated prisons and most important of all it will be giving people the choice. If somebody wants to mess themselves up by putting a load of dodgy chemicals in their body then let them! Drugs will become safter as a result, with legally-enforceable quality guidelines (no more coke cut with talcum powder), and it will give a massive boost to the economy as tourists flock here from all over the universe to get out of their faces and spend a load of money at British businesses.
