Well I'm gonna be kinda blunt here. At least you guys can have weed. Do you really think this is all that enforceable? They have a cigarette smoking ban in the NE(Ohio and PA), but I'll be damned if you don't see someone smoking a cigarette right outside the door of any starbucks at almost any time of the day.
I may have read the article wrong but it doesn't sound like the end of the world nor the cannabis movement. Keep your heads high(har har har), we've made tons of progress these past couple years.
Also edibles are a wonder.
I love getting comatose stoned off of candy.
