As opposed to the current patchwork of states that have legalized either medical marijuana, its recreational use, or both, the analysis looked at what could happen if the U.S. government made it legal to sell marijuana nationwide and included these major findings:
If full legalization occurred in all 50 states today, there would be an excess of 782,000 jobs, and would increase to 1.1 million jobs by 2025.Full legalization would result in more legal businesses participating in the market, more consumers participating in the legal market, and more employees on official payrolls, resulting in $4 billion in payroll taxes. By 2025, payroll deductions would increase to $5.9 billion.Assuming a sales tax at the federal level was implemented at 15%, the total tax revenues from 2017–2025 would theoretically be $51.7 billion. This amount of revenue would be entirely new revenue to the U.S. Treasury, as there are currently no federal sales or excise taxes.By combining the business tax revenues, the payroll withholdings based on the theoretical employment required to support the industry, and the 15% retail sales tax, one can calculate the total federal tax revenue potential of legalization: The combined total is estimated to be $131.8 billion.The difference between the current structure and the theoretical model is a $76.8 billion increase in federal tax revenues.
The new data comes in the wake of polling that shows historic levels of support for marijuana legalization nationwide. In October of 2017, a Gallup survey found that 64 percent of Americans now favor legal marijuana—the highest level ever recorded. It's also an issue that receives backing from people across the political spectrum. According to the Gallup poll, a majority of Republicans (51%) are in favor while Independents (67%) and Democrats (72%) support legalization at even higher levels.
