The current legal regime for the regulation – I use the term advisedly – of drugs has many unintended consequences. One of its minor tragedies is the number of thinkers and activists whose valuable energies are thus diverted to the Sisyphean labour of undoing it. So many words have now been written on the failure of prohibition that there is surely little more to be added. More than a decade ago, former Senator Peter Baume expressed it well: ‘Our strategies seek to prevent the production of certain designated illegal substances, and fail to do so; they seek to prevent the importation of substances, and fail to do so; they seek to prevent the distribution of substances, and fail to do so; they seek to prevent the sale and use of substances, and fail to do so.’ Instead, our laws and policies make all these activities that much more dangerous, more corrupt, more poisonous and more destructive.
