Think about it some more. As with many laws, this likely comes from a corporation trying to outlaw its competitors. As the article states, normal cigarettes will still be available. Does that seem reasonable, given the ostensible reason for this ban?
Makes sense. We should probably ban alcohol, driving, going outside when it's too hot / cold, weapons of all sorts, owning pets, ice skating, rock climbing, activities which raise the heart rate above resting, etc. Anything that has the potential for a negative outcome (no matter how isolated) has got to go. Also, don't even get me started on candy, bikes, skateboards, monkey bars; anything that kids could use, but potentially not fully understand is a risk to society. A risk we simply cannot afford when the earth's population is so concerningly low. Brb whippet break.
San Francisco has a significant percentage of people who completely ignore a slew of basic laws, like not doing hard drugs in public, not littering the sidewalk with used beedles, not stealing and not defecating on its streets.
