My high school classmate and, coincidentally, my SO's friend from college is currently doing time for "possession of large amounts of marijuana" - 19g to be specific.

He used to be a local weed dealer and while he knew what he was getting into and was consciously breaking the law at the time, after his first arrest a few years ago he stopped and got a regular job.

He only got involved with the court again because one acquaintance of his was charged with drug dealing and figured he could lessen his sentence by giving the authorities someone else to prosecute.

All in all a person who could otherwise continue to be a productive member of society has to spend two years in prison now.
