“These events are like farmers’ markets, bazaars or flea markets. Except in this case, vendors are showing off and “gifting” marijuana: you buy a $50 baseball card, comic book or sticker, and in exchange you walk away with a free gift of marijuana in just about any form you could want. Under Initiative 71, the city’s voter-approved marijuana legalization law that took effect three years ago this month, giving away small amounts of marijuana is perfectly legal, as is possessing it and growing and using it at home.”
