Marijuana is already legal for a majority of Americans

In a year the factory will produce 40,000 pounds (18,100 kilograms) of weed, with fewer than 100 workers. All manner of high-tech wizardry is involved. In the greenhouses temperature, light and moisture are all automatically adjusted. At harvest, threshing machines separate the bud, leaves and stems. Distillation machines heat some of the produce to break out pure thc—the primary active ingredient of marijuana. Another machine automatically mixes this with glycerin to make vape juice. All through the process those yellow tags follow the produce, allowing officials to trace the provenance of any cannabis product made in the factory.
