Laws are made by humans, and there is no guarantee that they are fair or ethical. The man in the article was caught with a couple cigarettes filled with a shredded plant (the illegal one, not that legal yet much more harmful plant). He served a felony for it because we instituted a draconian and racist class war under the guise of "saving the children from reefer madness". This country is finally instituting some sensible drug legislation, but the people that were most disproportionately affected by the War on Drugs are now disproportionately locked out of this new market. That is neither fair nor ethical.
