Colorado has such a tight smoking ban, they don't even want herbal cigs used onstage.  I think they may have closed a show in some larger town (Denver? Boulder?).  It hasn't come up yet for us, character who requested cig didn't smoke it, just handled it.  Basically the Colorado ban applies to any substance packaged for smoking, which apparently includes roll your own.  I'm thinking there's a few plays you pretty much couldn't do with such tight restrictions.

We have had smoking restrictions in theatre auditoriums & public assembly areas from way back in the 1900's. Which was extended to include pubs, all buildings & public transport systems, about 7 years ago.
Yet there is still fags smoked on stage at pro venues, when it is part of the script. But not allowed in venues used by amatuer theatre.
Actualy the strangest breach of the smoking ban, where smoking took place on a stage, was for the production of 'Steaming'. Although it was sponsored by Healthways 'Smoke free zone', quite a few fags were devoured during it? Yet the government department never turned a hair & chose to ignore it, but still fronted up the sponsorship money.
{maybe the punters never noticed & were distracted. As they were smoked by naked women in the show.]
To my mind substituting herbal fags is stll smoking the same as tabacco - which is a herb the same as any 'puff'n stuff or wacky weed'.
As suggested there is ways & means of simulating smoking, without lighting up.

Originally posted by Topper As far as I know: murder, rape, incest, adultery, and assault are also illegal in many municipalities yet actors continue to exhibit these behaviors onstage without any interference from law enforcement authorities. I'm not a smoker, and I detest the use of tobacco products, but I'm pretty sure the theater will soon be the ONLY place where people can watch others smoke in public.
