Delaware turns green Friday — in more ways than one — as recreational marijuana sales officially launch across the state. Starting Aug. 1, adults 21 and older with valid government-issued ID can legally purchase marijuana at 13 approved dispensaries.

Delaware law does not allow anyone to possess more than a "personal use quantity," which the state weed office defines as 1 ounce or less of marijuana in the form of leaf marijuana, up to 12 grams of concentrated cannabis, or cannabis products containing 750 milligrams or less of delta-9 THC.

The launch at existing medical dispensaries comes more than two years after legalization, but a key cannabis advocate is calling for a boycott.
