Addiction is often an unexpected affliction. The person addicted doesn't realize the drug he is taking is an opiate until its too late. We are supposed to be able to trust our doctors, and our government. Drs who ask if you have ever smoked marijuana know you are susceptible to opiate addiction (that is why dope is notoriously known as a gateway drug).  Right now organized crime runs things. A boy with a broken leg becomes the next homeless man in the street.
