Something must have gone wrong in his childhood :)
Like the author said in Forbes, crime rate in Colorado actually dropped 14% ever since MJ was legalized.
We can't really neglect the Fed and/or Session, because the MJ industry is so fragile. Any crackdown is gonna hurt the industry, especially an increase in enforcement
However, looking at the good side, there are more states lining to legalize weed in 2017. And even better, the bill to reschedule Marijuana (H.R.715) is already introduced to the House. Actually, the progress is looking decent :)
But I also cannot imagine if the bill got turned down...since the Fed / Session does not seem to support MJ (also tighter restriction on Med. MJ)
