An accessible, tight, comprehensive guide to marijuana law in the U.S. of A., as of June 2018. Medical marijuana has been legalized in 29 States and Washington D.C., recreational marijuana in 9 states and D.C., yet on the federal level marijuana remains illegal, bringing rise to complex issues of law for the budding industry. Herein you'll find: key cannabis data and dates, case law highlights, essential statutes and standards, and the abstract and excerpt from "Native Marijuana: American Indian Sovereignty v. Federal Drug Policy", featuring an original interview with the leader of a federally-recognized tribe. All the essentials of marijuana law rolled into 4 chapters and 20 or so pages to elevate your understanding. Stay tuned for further works in the author's 4:20 law series, including "Marijuana Case Law in 4:20" and "Native Marijuana Law in 4:20". Until then, stay lifted and stay legal.
