San Francisco is the only place I&#x27;ve ever seen custom glass funnels for sale at headshops.<p>SF is also the only place I&#x27;ve ever seen flyers advertising a Whipit delivery service (nitrous oxide).<p>Generally speaking SF seems to be much more loose with drug use than other cities in CA - although I will say, from what I&#x27;ve seen, the use of pharmaceuticals like benzos and adderal seem to be treated as lightly as alcohol these days.
