Herbalist checking in.
It’s mentioned in the staff report linked above, but I’ll just echo it here:
There are no safe herbal cigarrettes any more than there are safe tobacco cigarrettes.
*All *plants have some amount of nasty stuff in them you don’t want in your lungs. Chemicals aside, hot dry air is very bad for your lungs. Many herbs used in herbal smokes actually have more tar in them than tobacco.
But it is possible to make an herbal smoke without nicotine, without many of the chemicals commonly used in cigarrettes that you hear the Truth Campaign going on about (is it just me, or do those asshats make you want to light up?) My suggestion is to roll your own from herbs you know the origin of. It’s really pretty easy.
When I was quitting, I used an injector “roller” and preformed cigarrette tubes to make smokes that were 1/2 tobacco and 1/2 herbal, than 1/4 and 3/4. The injector is cheap, is very easy to use and is available at any tobacco shop or online. If you buy it in a shop, they’ll show you how to use it. They also look just like tobacco cigarrettes, including the filters, so you could make several to use onstage.
The best and least harmful herb for your lungs is mullein. Traditionally, mullein was actually smoked to aid in bronchitis, although, as I said, hot dry air (smoke) is never kind to the lungs. It’s pretty inoffensive in taste. It smells a little like pot to the uninitiated, though. Adding some peppermint leaves gives you a “menthol-like” smoke and hides some of the mullein smell. You can find both of these at Whole Foods in the nutrition department, in their bulk herbs section.
Myself, I won’t smoke purchased herbal smokes. They’re usually too dried out, which makes the cherry (burning end) fall out unpredictably, and they taste like ass. Also, some of them add the same chemicals tobacco cigs have in them to keep them burning steady and quicker. These chemicals are part of the carcinogen problem.
