Have you noticed the basic reason to smoke or otherwise ingest Marijuana and it by products is to get "high". Driving "high" is impaired driving as Washington, Oregon, Colorado and most other States have found, and the arrests and driving "high" on marijuana are on the increase. Was driving under the influence of alcohol not enough of a treat for you? Did  not enough  people die and get maimed to satisfy your blood-lust? Don't you get tired of innocent people getting killed or maimed?

I guess not or you would not have welcomed with open arms another class of impaired driver  on your roads with your wives and children as probable targets. 

Please drive defensively out there.
