It will bring the price down huh? Kinda like Cigarettes being legal so the price has come down, right?
The two would be quite different as the price of cigs can be blamed on unique circumstances all thanks to opportunistic lawyers and politicians. Could prices go up? Possibly, but using simple economics and history of prices of things that are illegal vs legal, I'd place my bet that prices would come down. The more important goals is to stop the crime associated with drugs, dismantle the murderous cartels, and bring some common sense into the war on drugs which hasn't worked and never will. It's funny how conservatives are all for reforming welfare and other bloated government programs that were failures and hurt people yet they won't admit the war on drugs is a failure.
If they were illegal, they would sell for $3 each. Not each pack. Each cigarette.
