It says that projections show by 2020 the legal pot industry will create more jobs in America than the government, utilities companies or manufacturing. The article says they actually expect a decline in manufacturing jobs of about 800K while the pot industry will create about 250K jobs.
Of course, the manufacturing part of that could chance depending on what Trump does.
