I would suggest taking a look at this: https://theweedlynews.com/2016/08/15/the-truth-about-auma/
None of the money goes to the general fund (roads, schools, etc)
Whole new section of appointed (not elected) officials with money to play with.
Majority vote overturns any of the sections without our input.
It creates new marijuana related felonies.
15% excise tax + state + local use + sales.
