Weed got serious in the 90's where THC levels were regularly in the %20+ range thanks to superior genetics and growing techniques. When evaluating the stats one should look at it from the 70's to now to see if there are any changes due to consumption. Those stats are probably not available because it wasn't a problem then like now. Its just self interest groups like MADD and the government are always looking for new ways to promote themselves and secure new streams of revenue through enforcement.
Driving stoned from weed is nothing like being drunk. They are not even comparable.
