Legal highs and their risks are a direct consequence of the prohibition and criminalisation of certain drugs which are probably less dangerous health-wise. The Conservative response is always going to be 'ban it', unfortunately. This will not address health risks of drug consumption, but it will keep many older Conservative voters happy, as they will see the government as being 'responsible' and 'taking action'. I really cannot wait until Millennials are running (and voting for) majority governments, this current approach to drugs will seem prehistoric.
