In the times of Elizabeth I if you farmed more than 70 acres of land it was an offence not to grow at least one acre of cannabis hemp. England needed hemp, it clothed us, it provided the rope and sails for an expanding navy, paper, oil, food and 101 other uses. It has been called the basis of the British Hempire.
Now just one Elizabeth later, you can get your door smashed down, your bank account monitored, your phone tapped, stopped, searched, tested and arrested and slung in jail for growing just one plant let alone an acre.
