The marijuana industry is expected to grow substantially over the next few years, with sales in the United States alone forecast to hit $23.4 billion by 2022, according to cannabis market research group Arcview. Presently, there are nine states, and the District of Columbia, that have legalized marijuana for recreational purposes and thirty states have given the green light for medicinal use. In light of next month’s mid-term elections, four additional states will consider legalizing some type of marijuana use. Should all vote in favor of legalization, recreational marijuana will then become legal in eleven states and D.C, and in thirty-three for medicinal purposes. Following the elections, the White House intends to tackle the federal marijuana reform, according to Rep. Dana Rohrabacher, R-Calif. Rohrabacher has stated that President Trump has spoken in support of legalizing medical marijuana on a federal level, while keeping the legalization of recreational marijuana in control of each state.
