There is a smoking shelter like that in the car park at the hospital in Halifax. I was talking to the porter who wheeled me down for my CT scan in 2012 and he told me that one young man with serious health problems was so desperate for a cigarette that he got his mates to unplug his monitors etc and wheel his hospital bed out of the ward, down the corridor to the lift, down to the ground floor, along another corridor, out of the main entrance and across the car park so he could light up ...!
An old chap in my ward was irate that there was nowhere to smoke so he lit a fag and leaned out of the window. The smoke immediately blew back over us. I wasn't impressed since I was only getting about 10% of the oxygen I needed anyway because of my clotted lungs, and the smoke only made matters worse. The ward nurse was even less impressed and made her feelings very clear!
