Wall Street Journal, 03 Jun 2013 – LOS ANGELES – A union of medical-marijuana workers in this city is betting on a smaller, but healthier, pot-dispensary business. The United Food and Commercial Workers Local 770 backed Proposition D, the Medical Marijuana Regulation and Taxation Ordinance, which passed with 63% of the vote in citywide balloting last month. That measure would ban all medical-marijuana businesses except for about 135 more-established shops, several of which employ UFCW-organized workers.
