are criminals going through tobacco fields stealing crops?  I used to live on the edge of tobacco country - a legalized intoxicant - and the crops grow out in the unsecured open without fences even.  Why would pot be any different, once legalized and readily available in regulated and tested dosages?  I really doubt folks would bother to go to the trouble of stealing and drying pot plants when you can buy a nice prepared and ready to use MJ product cheap down at the local liquor store.
