As can be imagined, the April 20 celebrations across Colorado and Washington, as well as other marijuana friendly states like California and Oregon, will be joyful, well attended and burgeoning with cannabis products. It might even feel as if marijuana is already legal, but it isn't, and, in some states, the need for secret codes is still very much alive. In Oklahoma, manufacturing hash carries a mandatory two year prison term but can also mean life in prison. Under Louisiana law, a second pot possession conviction is classified as a felony offense, punishable by up to five years in prison. Three time offenders face up to 20 years in prison. And in Florida, possession of more than 20 grams of marijuana, as well as the cultivation of even a single plant, is a felony offense and punishable by up to five years in prison and a $5,000 fine. - CNN
