In 1996, Californians voted for the legalisation of Cannabis for medicinal purposes. But this kind of liberal attitude has not been welcomed by the White House. "We believe that the legalisation is a smokescreen - the real agenda is to make all drugs legal," posits the Mayor of the Drug Enforcement Administration. 'Legal' Cannabis farmer Ed Rosenthal soon found himself at the centre of a very 'political' trial. Despite being allowed to grow the plant by state authorities, the federal judge refused to let the jury hear evidence to his defence. Many see him as a 'political prisoner' and anger is spreading as those with terminal diseases are being denied this unique form of pain relief.
