text: Laws are meant to establish social paradigms of conduct. Sociology states that it is impossible for every individual to behave according to standarts in a society. In simple words, there will always be someone who will break the law, or behave incorrectly. Marijuana, if used moderately and according to the "correct" standarts (medicine for example), is harmless, but since it is impossible for every individual to follow the same path of correct behavior, we conclude that there would always be misuses of marijuana...and there's where laws enter...to ensure that a majority behaves well. \n\nAlso...laws are always broken...if you abolish a law that is broken so often, you would only increase that illegal conduct.
