It sure will!!!!! check out the poll in cali http://www.californiapropositions.org/

Proposition 19 is not likely to pass because it is on the mid term ballot and low voter turnout is likely in any midterm ballot measure. Those who are most likely to vote are most likely to vote against it.

Proposition 19 does not address the issue of industrial cannabis/hemp and is not so much legalization as a broad decriminalization.

If it does pass it will likely have minimal effect on things as it will still be illegal to smoke or possess marijuana in public so all current laws effecting that will remain intact, that is use in any given business will still be prohibited along with any business/employee prohibitions.

That being said ^ it is unlikely that industrial hem/cannabis will gain ground without the legalization of marijuana 1st and the cannabis plant has a great many potential uses to it other than the drug marijuana.
