Smoking has been identified as the single greatest cause of preventable illness and premature death in all 4 nations of the U.K.
Annually, in Scotland approximately 10,000 die, in Wales, 5000, and in N.I. 2300.
In 2019 in England alone, there were 489,300 admissions to hospital attributable to smoking, and 77,800 died.
