Here’s something to think about: How many police officers and sheriff’s deputies are involved in investigating and solving crimes involving illegal drugs? And arresting and transporting and interrogating and jailing the suspects?

How many prosecutors and their staffs spend time prosecuting drug cases? How many defense lawyers spend their time defending drug suspects?

How many hours of courtroom time are devoted to drug trials? How many judges, bailiffs, courtroom security officers, stenographers, etc., spend their time on drug trials?

How many prison cells are filled with drug offenders? And how many corrections officers does it take to guard them? How much food do these convicts consume?

And when they get out, how many parole and probation officers does it take to supervise their release? And how many ex-offenders turn right around and do it again?

So how’s this war on drugs going?

Someone described insanity as doing the same thing over and over and expecting a different result each time. That’s a perfect description of the war on drugs.

The United States is the largest illegal drug market in the world. Americans want their weed, crack, cocaine, heroin, whatever. And they’re willing to pay big money to get it.

The drug suppliers are only too happy to oblige. The Mexican drug cartels now have operations in 230 American cities. That’s 230 American cities!

And we’re not just talking about border towns, but places such as Anchorage, Alaska; Boston, Massachusetts; Atlanta, Georgia; and Billings, Montana. They’re everywhere. And they don’t just bring drugs, but violence and crime as well — lots of it at no extra charge.

They have been able to infiltrate those 230 cities because we have not bothered to secure our borders. In addition to illegal aliens who come here to work and avail themselves of our social programs, we have criminals from Mexico bringing drugs in, taking money and guns back, and recruiting American kids into their criminal enterprises while they’re here. iReport.com: Is it time to legalize pot?

What do you suppose the total price tag is for this failed war on drugs? One senior Harvard economist estimates we spend $44 billion a year fighting the war on drugs. He says if they were legal, governments would realize about $33 billion a year in tax revenue. Net swing of $77 billion. Could we use that money today for something else? You bet your ass we could. Plus the cartels would be out of business. Instantly. Goodbye crime and violence.

If drugs were legalized, we could empty out a lot of our prison cells. People will use this stuff whether it’s legal or not. Just like they do booze. And you could make the argument that in some cases alcohol is just as dangerous as some drugs. I know.

Like I said … something to think about. It’s time.
