No, nor was it a surprise when criminals got involved in alcohol during Prohibition. The right answer, then and now, is legalization.
I am inclined to agree. Just a sidebar. Here in Florida we had early release programs because of jail overcrowding. One newspaper published the names of those being released and their crimes. The list was very scary; rape, second degree murder, assault, robbery, manslaughter and other crimes against persons and property had been commited by these released criminals. Oddly enough not a single person on the list had been jailed because of drugs. Since I know Florida has jail time for pot- possesion. Having more than a certain number of grams is a felony- I have to assume those people stayed in jail. That just does not cut it with me. Justice system resources are stretched very, very thin and it is a waste to use the resources against pot smokers. I don't smoke but thats cause even though I disagree with the law I still will obey it. Plus who the heck has money for pot after taking care of all the other grown up obligations?
