Many people here at FR believe that the iron fist of government is the solution to everything involving drugs.
The government’s argument is ‘drugs will ruin your life so if we catch you using them we will ruin your life.’
The opposite position is based on the false belief that drugs won't get millions of people killed if they are legalized. Since I firmly believe that total legalization of all drugs will eventually kill more people per year than World War II, (It will take awhile to get that bad) I can't think of why we wouldn't want to use the Iron Fist of government on it. If a government won't protect it's citizens, it won't be a government long.
I point your attention to China where they did legalize drugs, and they Did collapse the government. That government had lasted for over three thousand years, but after 70 years of legalized Opium it came crashing down. The Replacement government came crashing down too.
Do you know what took it's place? A Dictatorship. Mao solved China's drug problem by executing anyone caught with drugs.
Not a good road to travel I assure you.
