To recap, the June 26 election a “yes” or “no” vote could determine whether or not the cultivation, possession and use of marijuana for medical purposes will be permitted.
As of now, the medical use of marijuana is illegal on a federal level, obviously. And there will be limits as to how much of the substance one can carry on their person.
On January 13, 2018, two separate political committees registered to support the vote (also known as the state Question 788)
