Dear 'Old Holborn'
Look closely: that's not a tab, it's a spliff - and can you see any smoke?
Auntie did hope that spliffs would be exempted from the smoking ban but the Health Act 2006 specifies that it includes 'smoking any other substance'. (So that rules out crack, smack and dried banana skins, too, in case you're tempted.) In fact, the act prohibits merely 'being in possession of [tobacco or] any other lit substance in a form in which it could be smoked', even if you don't actually smoke it. That unlit spliff of mine is about as far as you can go in a designated 'smokefree place' without defying the law.
There are exemptions. These include hotels, care homes, prisons and 'other places where a person may be detained'. So there's nothing to stop you lighting up in a police cell, then. It's also okay for 'those participating as performers in a performance' to light up 'if the artistic integrity of the performance makes it appropriate for them to smoke'. You could always become a performance artist in residence at your local, with performances repeated at, say, 30 minute intervals, and see where 'integrity' gets you.
Auntie will mention only in passing that Hitler once suggested that the Nazis would never have come to power if he hadn't given up smoking. Or that one of the few acts of Pope Urban VII's 13 days in office involved a threat to excommunicate anyone who 'took tobacco in the porchway of or inside a church, whether it be by chewing it, smoking it with a pipe or sniffing it in powdered form through the nose'. (Watch out for a sudden boom in the snuff business, by the way, as a byproduct of the ban.)
These little nuggets may be worth sharing with the rest of your fellow slow-suiciders on 1 July. Auntie would have given up smoking years ago if the Health Fascists weren't such an unattractive bunch.
