Clash between cannabis and wine

Read this article today about how farmers in Santa Barbara are growing cannabis for recreational consumption. Farmers found that fungicides from a near by vineyard was getting on to the cannabis crops (by law, cannabis cannot be treated in such a way). This has caused problems between farmers.

2 things I noticed:

1. Cannabis takes up less space than vineyards.

2. Cannabis creates more money per acre than vineyards.

I have read and heard many in the wine world thumbing their nose at canna-business, but we need to start taking this extremely seriously. Think of the financial and political power that canna-business will yield in the decades to come in the largest wine producing state in the US.

Opinions?
