The war on drugs propaganda is really not much different than the scary stuff the anti-gunners throw at us all day long.
Thankfully, we are able to keep the anti-gunners at bay (somewhat). For instance, more states continually sign on to the doctrine of RTC (right to carry). Amazingly, crime does NOT increase with RTC, in fact, it typically decreases (as we all know). I would imagine many rabid anti-gunners are astonished by this fact.
In my opinion, the same will happen once we change tactics with the ridiculous war on drugs. A simple step like legalizing MJ will immediately put a huge dent in the drug cartel pocketbooks, plus it will allow our law enforcement and judicial system to focus on real crime. Heck, we can even tax and regulate the stuff, and it will then probably be HARDER for our under-age kids to buy it.
Who cares if our agencies confiscate millions of pounds of illicit drugs; there will only be many millions more pounds to replace those. Our kids can easily buy all the drugs they want RIGHT NOW. The war on drugs is not stopping them from buying drugs, WE - as parents - ARE THE ONLY THING STOPPING THEM.
