Makes one wonder if each household (or person?) may be allowed to grow four plants it might have serious implications.  Can you have the plants in your garden during the summer, and if so will you be required to have a doberman protecting your plants from curious young folks?  If it grows like a dandelion in the summer, why would you ever fork out money to have someone grow your weed?  We pay people to kill our dandelions - at least we did before we were greened.   Maybe they will have a plant tax, so each seed will cost hundreds of dollars.  And then they could have the police make sure no one allows their bud to go to seed, because they really are not all that busy!   Lots of work needed on this file Justy.
