Legislative History
Missouri legalized medical cannabis in 2018 through Amendment 2, establishing a patient registration and dispensary system. Recreational cannabis was legalized for adults 21+ in 2022 via Amendment 3, permitting possession of up to 3 ounces, home cultivation of up to six flowering plants, and licensed retail sales with automatic expungement for certain prior offenses.
Law Enforcement
Confiscation was the usual outcome, and the fines and tickets were unevenly enforced. Police pushed back on a voter-approved ordinance, which ended in a compromise. First offenses were often described as deferred, with a year out of trouble said to keep the offense off someone’s record. Missouri has since introduced adult-use rules, as covered in Marijuana Laws.
Where to Buy Marijuana
Downtown and the nearby University of Missouri campus were the main places to meet people. The counterculture crowd usually knew somebody, and nugget was widespread on campus.
Marijuana Prices
- Schwag: US$20–25 for a quarter or US$90–100 for an ounce
- Mids: US$20–40 for an eighth
- Kind bud or dank: US$50–60 for an eighth, US$90–120 for a quarter and US$350–450 for an ounce
Types of Marijuana
College contacts turned up plenty of schwag. Small homegrown brands existed but were uncommon. Better flower came from across the country, though much of it was from Missouri farming towns or hydro growers in Kansas City and St. Louis. Granddaddy Purp and Purple Haze both came up. Sativas and indicas were around, with hybrids most common.
More Information
Columbia sits about a hundred miles from both Kansas City and St. Louis. It has both progressive and traditional sides, with downtown head shops, bars, restaurants and clubs. The Peace Nook on Broadway and Ragtag on Tenth Street were favourites. Parks were plentiful, with state parks and camping within a 20–30 minute drive. For a smoker, Columbia felt like a good place to live.
