This is creative writing. The cards are on the table from the first paragraph: > At smoke shops, customers drive off after blazing up. In motion or at red lights, smoke wafts from car windows, the smell mingling with exhaust fumes in a pungent miasma. It's the classic formula: invent a conclusion first and make that your headline; spend a few paragraphs painting a visceral picture of your imaginary world; then find 2 or 3 city-dwelling folks who have some tangential and/or non-authoritative opinions on the topic. (The first primary source cited here is a bike messenger, and it doesn't get any better.) Add a bunch of statistics and past incidents that are vaguely related to the topic but not actually indicative of the conclusion. Job done.
