The Report of the FCDA, Europe, on Cannabis, it could be grown in huge quantities on waste land; the tops and heads available for medicinal and recreational use, the seed used as food and animal food, the seed oils used too, the hurd and textiles used for clothing, paper, canvas, even building bricks and chitboard, and plastics too - what is left used to make biofuels, safely, easily, locally and environmentally friendly. Anything left, thrown back into the land. The revenue from sales of bud would mean virtually free fuel!
The people would gain more independence from giant petrochemical and pharmaceutical companies, from drug dealers, suffer less pollution and save money.
Any Government that refuses to acknowldge that are liars.
Any Government that still claims that the harm caused by cannabis outweighs the benefits, are either fools or have a vested interest in prohibition, just like the alcohol-gangster-supporting prohibitionists in the USA that supporteed alcohol prohibition last century.
