Vast changes Ohio Senate Republicans propose to marijuana legalization measure.

Banning marijuana growing at home, increasing the substance’s tax rate and altering how those taxes get distributed, are among vast changes Ohio Senate Republicans propose to a marijuana legalization measure, approved by voters last month. The changes emerged suddenly in committee just days before the new law is set to take effect, though their fate in the full Senate and the GOP-led House is still unclear. The ballot measure, dubbed Issue 2, passed on the Nov. 7 election with 57% of the vote and it set to become law this Thursday, making Ohio the 24th state to legalize marijuana for adult recreational use.
