In all seriousness, this is probably true. Marijuana is BC's 2nd largest industry behind construction and ahead of forestry. I believe it contributes over $7 billion/year to our GDP. I'm sure there are articles somewhere to back this up. :) Had Prop 19 passed it would have been bad news for BC's economy.
Regardless of Prop 19, WA has legalization initiatives in the hopper. We were supposed to get one on the ballot this year, but the petitioning campaign was poorly organized (and lost a lot of signatures).
