Before Washington state voters legalized marijuana in the 2012 election, pot was easy enough to access on the black market. Five percent of state residents have used the drug in one form or another while burning through a remarkable 187,000 pounds per year, according to estimates by Washington’s Office of Financial Management. Getting high without getting arrested wasn’t much of a problem, either. Washington decriminalized medical marijuana 15 years ago, and today dozens of dispensaries are operating under protection of state law. In addition, Washington’s biggest city, Seattle, had instructed its police force to treat personal possession of marijuana as the lowest law-enforcement priority.
