President Donald Trump signed the bipartisan Farm Bill into law in December of last year, which legalized hemp — a plant that’s roughly identical to marijuana but doesn’t contain THC, a psychoactive compound in marijuana — nationwide.
Hemp is also a source of CBD, or cannabidiol, a popular, if scientifically untested ingredient in many cannabis-infused products.
In last year’s midterm elections, Michigan became the 10th state to legalize recreational marijuana, and Utah and Missouri voted to legalize medical marijuana.
Deep-red Oklahoma also voted to legalize medical marijuana last year, joining numerous other states that have such laws on the books.
Vermont became the first state to legalize marijuana through its Legislature last year as well, rather than a ballot initiative when the governor signed the bill into law.
Ten states and Washington, DC, have now legalized marijuana for recreational use for adults over 21. And 33 states have legalized medical marijuana.
Marijuana prohibition began 80 years ago when the federal government banned the sale, cultivation, and use of the cannabis plant. It remains illegal at the federal level.
Overturning prohibition is one of the few hot-button topics with widespread support.
A recent poll by the Pew Research Center found that 62% of Americans, including 74% of millennials, said they supported legalizing marijuana.
Last year was also a banner year for marijuana legalization globally.
Last, October Canada legalized marijuana federally, becoming the first G7 country to do so.
Mexico’s Supreme Court also ruled that marijuana prohibition is unconstitutional, paving the way for the country’s new leader, Andrés Manuel López Obrador, to follow Canada’s lead.
