What???
Canada's proposed law says pot is LEGAL in Canada (< 15 grams). In Ohio, it's ILLEGAL. You can be fined in Ohio.
It isn't being legalized, merely decriminalized. Possession will still be illegal, but if it's less than 15g there will be no jail time or criminal record.
IMO this proposal is the worst of all possible worlds. Outright legalization would be a devastating blow to organized crime and deprive terrorist groups of a lucrative source of income. This solution merely reduces the consequences of pot use without changing its status, which means the market for criminals will expand.
