Is it better to put drug addicts in jail or to send them to mandatory drug treatment programs?

In my personal opinion I feel that drug addicts would benefit more from a drug treatment and rehab program than being placed in a jail cell. I feel that the drug dealers and trafficers are the criminal and the user is the victim. Yes, I know life is about choices, and it is hard for me to understand why anyone would make the choice to do drugs but unfortunately we humans do make bad choices. Some of us are lucky and may experiment with illegal substances only once or twice but some of us seem to be more prone to becoming addicted. There are many types of drugs out there, even food can be an addictive substance for some. What compels one to use and become addicted is not for me to judge as I do not walk in their shoes. That is not to say that I am soft on people that use as I find many of their justifications for doing so absurd and silly. Many say that their reason is because they had a dysfunctional family life but we all have had our cross to bear so I don't buy that either. I believe that there's something within our "makeup" that keeps us on one side of the street or the other. However, I also don't think that jail time will cure their desire or their addiction to the substance. Many will just do their time and be out on the streets searching for their drug of choice all over again. People who are addicts will sell thier soul to get their fix. Also, I believe that until someone wants to get help and admits that they need help will they benefit from a treatment program. Its a hard problem for our society to deal with...there is no "one size fits" all answer to this problem!
