April 20 brings a chance to stop and reflect on the draconian marijuana laws still threatening so many Americans. In addition to the lives harmed by arrests and incarceration, the economic costs of prohibition are enormous. The war on drugs has cost at least $1 trillion since it was announced in 1971 by President Nixon. The term 420 began as a secret code. But 40 years later, in some states the need for a code has given way to cannabis pride and open celebration. In other places, people will smoke or otherwise consume pot in private parties. And for those in prison and jails and for their loved ones, it will be just another sad day. - CNN
