I really dont see drugs and people using them as the main problem here. Drugs have been around since the beginning of mankind. Meth has even been around for about 60-70years. You used to be able to buy heroin through the local paper , mail order with a syringe. If drugs werent so readily available they would not be sucked up the Americans.
My complaint is drug trafficking.... It is the problem,in my oppinion. Anyone can be next in line to make the money , most say its the Asians ,but when no one even knows your name because your illegal , hell its a free market. Get caught , change your name and do it again....Some one gets in your way , get rid of them and change your name. South of the border they have "bred" generations of drug traffickers. No names , killers that kill families and anyone that gets in the way. Secureing are borders would solve or put a big dent of a ton of problems...
