Ohio is on course to become the 24th US state to legalise the cultivation and sale of recreational cannabis after voters backed the measure at the polls this week.
A referendum held as part of the state's Tuesday election day returned roughly 56% support for legalisation among those who cast ballots.
If the current proposals proceed, adults aged 21 and over would be allowed to grow cannabis at home, and could possess and gift up to 2.5 ounces of cannabis and 15 grams of extract.
Reform advocates, however, face an uncertain wait to find out whether the public's verdict will be honoured, given that Ohio's Republican-controlled general assembly holds the authority to amend or repeal the legislation entirely.
The prospect of outright repeal seems remote, though, after Republican Ohio state representative Josh Williams — himself an opponent of legalisation — told a webinar last month that the wishes of voters must be respected.
“Whether that is ill-advised or not is a different subject,” he added.
The Ohio result has been welcomed by cannabis reform advocates across the US, who have had a mixed year in their push to end prohibition.
Last November, Maryland and Missouri voted in favour of legalisation, while North and South Dakota rejected comparable measures. Oklahoma similarly voted down an end to prohibition in March, before Minnesota and Delaware both moved to permit adult cannabis use.
The National Organisation for the Reform of Marijuana Laws (NORML) released a statement arguing that legalisation is an issue with appeal across party lines, drawing support from Democrats, Republicans, and Independents alike.
“Ohioans have seen similar legalisation laws adopted in neighbouring states, and they know that regulating the cannabis market is preferable to the failed policy of prohibition,” NORML deputy director Paul Armentano said.
“It is imperative that elected officials respect the voters’ decision and implement this measure in a manner that is consistent with the sentiments of the majority of the electorate.”
Washington DC has also legalised adult cannabis use, joining the 24 states that have now done so.
