If San Francisco was distilled, bottled and sold as perfume, what you'd get is unmistakably cannabic - enhanced with notes of Mexican food from La Taqueria and the scent of progressive politics. Head to Dolores Park in the afternoon and you'll realise taking a bong out of your bag won't raise any eyebrows. Between the speakers blasting music from every corner, the woman hula-hooping and the group practising capoeira, it'd almost be rude not to light up and add to the fun. Alternatively, grab an edible from a dispensary (of which SF has many) and wander around town. If there's one place you won't feel paranoid, it's this liberal hub of art and culture.
