You mean like Rite Aid, Walgreens,Safeway etc.?  
  Making cannabis  Illegal and prohibiting it for all these years is what created the MJ cartels. If all these years of arresting citizens for enjoying a God given herb hasn't eliminated the cartels why do you think signing another petition will? If you really wanted to eliminate the MJ cartels and dealers you would support Re-Legalization and allow Adults to grow what they want to grow.
