A lot. We've had the "big 5" industries fighting against us for decades: * Pharma (because of the amazing and un-patentable medical applications of it) * Private Criminal Justice and Police Unions (Marijuana is one of the easiest things to make an arrest on--private prisons profit, probation companies profit, inmate phone services, phone providers, ankle bracelet companies, police equipment companies, etc. all profit. For Police Unions, marijuana-related crimes accounting for a sizable percentage of police stops and arrests, legal weed means less jobs and potentially lower pay. Additionally, Marijuana is easy to identify from a distance due to smell, and gives an officer probable cause to make a stop and search for other illegal activity) * Paper/Textiles (Hemp!) * Alcohol (Legal weed potentially means a loss of sales for the only major legal intoxicant.) * Tobacco (Legal weed means something for people to smoke that isn't a cigarette.) Some of these industries are shifting. Big Tobacco, for example, seems to be trying to join the party, and has made some moves that indicate a desire to enter the industry. I think Paper and Textiles either will come around or already are, as I think Hemp could be easily incorporated into the existing industry. But yeah, I believe that Big Pharma is as big of a part of this as police unions and Big Criminal Justice.
