The point is that there is no reason Washington state and B.C. should be different in that capacity. Their crime rates are quite similar for almost everything else, but in grow ops it's day and night. The only difference that I can attribute it to is sentencing, five years versus forfeiture of your light bulbs.
The only problem with that in Washington state is people growing on crown land and in forests where they don't have to worry about their homes being seized. We have more and more people from Washington state buying recreational property in the interior so they can come up, and the response from them is, “We're not allowed to do this back home.”
