That's a bit extreme (assuming you were not joking, if you were disregard this). Exposure is usually short and concentration low outside -> little/no health effects. The smell is bad, and personally I very much want to avoid it. But banning it is a bit harsh.
Again, if you were joking, ignore my post.
The reduction in asthma admissions is good news.
