How bad are Hollywood "fake" herbal cigarettes for you?

These are used in the production of TV shows and movies either for health reasons or because the actors are non-smokers, but how healthy are they?

If they are burning plant matter a lot of the downsides of cigs will still be present, carbon dioxide and some amount of tar and particulates.

If you’re a non-smoker on a show like Mad Men, over the run of the show that is a LOT of smoke to be inhaling.

According to this site they are Ecstacy herbal cigarettes, or maybe another brand called Honeyrose.

In the linked article, one of the actors jokes a bit about how safe they are, so the actors at least are aware of the risks.

I also found this, though I have no idea how accurate this site is:

There was a Straight Dope article about clove cigarettes years ago. Cecil claimed that they’d kill you faster than normal cigarettes.

Is this the one?

They don’t, however, produce nicotine, so you don’t get addicted to them and don’t have the urge to smoke them when not on the set.

This. It obviously takes a very large number of cigarettes to actually kill a person. If the lethal dose is 1 pack per day for 20 years, then that is 2036520 = 146k cigarettes. I’ve heard of smokers with 40 pack year smoking histories, so this probably isn’t quite enough to kill the average person. In any case, it’s the addiction that causes people to keep smoking. An actor who smokes a clover cigarette in a movie might not smoke more than 100-1000 of them his entire lifetime, factoring in multiple takes and multiple movies.

Clove cigarettes aren’t herbal cigarettes. Their main component is still good ol’ tobacco. Crushed cloves are added in to the tobacco mix.

Cecil alsowrote this articlespecifically about cigarettes’ use by actors in theater & film…

Yea but nicotine by itself is basically harmless(in the amounts possible to consume via cig, don’t make me beat a pedant!) this sounds like the line of argument that e-cigs are going to kill teens since it will somehow lead them to real cigs.

These herb cigs sound like they are almost as bad for your lungs in the immediate time frame as real cigs, so it seems kind of misguided. If they are concerned about second hand smoke in the workplace they are just as bad.

Oh and I wonder if any workplaces allow use of these in non acting situations but ban cigarettes?

Don’t be pendantic, please. Obvious it requires an addictive substance to make you keep using the product and a toxic delivery system to result in something that kills people commonly. This means that cigarettes lacking an addictive substance and e-cigs without the carcinogens are both safe.

Herbal cigarettes arguably do a non-zero amount of damage. The important thing is that the damage is so small that you’re significantly more likely to die of something else first. This is similar to what happens when you eat two Double Big Macs or do three shots of vodka on one or two occasions. Is it harmful? Yes, to some extent. Am I likely to seriously shorten my life if I do it once or twice? No.

Sorry I meant in the context of second hand smoke for the other crew members.
