Within a 10 mile (about 16 km for the rest of the world) radius from my house they busted a bunch of farms this year. The last I heard they had pulled up over 150,000 plants. But it hasn't seemed to have any effect on the supply around here in the San Francisco area. Certainly there's been no sign of a drought. Then again, 150,000 plants in California is like a grain of sand on a beach.

Question: Is most of the weed consumed in England grown there? Or, do you get it in from places like Netherlands or even Canada & the US?
