A few of the terms, like “terpenes” and “MMJ” (short for medical marijuana), are not actually slang terms. Other names on the list, like “shoe,” appear to be completely made up. Worse, “Devil’s Lettuce” is italicized in the report, revealing that the relatively old term was only added in this year.
Meanwhile, “blunts,” “good,” and “gas” were apparently not important enough to make the cut. Either that or no one at the DEA listens to Post Malone.
