I’m in an area of about 30,000 people. Two liquor stores and a dozen dispensaries, stores, if you prefer. A couple are waiting to open. Gotta be 21 to get in.
Yes, it will probably work like liquor - kids under 21 will scheme to get it from older "kids", or just plain strangers. "From an unrelated adult" is the most common way according to the below, by far (28%).
