Those of us who have supported the end of the marijuana prohibition have argued that the prohibition props up organized crime.  This was true with the alcohol prohibition in the last century and is still true for today for drugs, gambling and prostitution.  Yet I remember reading people being skeptical that the experiments in Colorado and Washington would have any meaningful impact.  Well according to several sources the limited legalization in the US is already having an impact on cartels and their growers.

Also, according to the ArcView Group:

“Legal marijuana is the fastest-growing industry in the United States and if the trend towards legalization spreads to all 50 states, marijuana could become larger than the organic food industry.
