The use of marijuana has carried a social stigma for so long its about time more people started standing out against the atrocity of banning a native plant.
(yes marijuana was here before we were and is found all over the globe.)
The United States government could avert two current disasters with the legalization of marijuana.
1st and foremost. The legalization of marijuana would release the grip the pharmacudical companies have on the prices of medication. NOBODY is going to buy super ass expensive pain pills when you can grow pot in your own home for pennies on the dollar.
2nd The local state and federal governments would be able to place tax on the purchase of marijuana and use this money for much needed local reform and to pay off the national debt as well.
The positive aspects greatly outweigh the accepted social standpoint and fears about marijuana.
