Hi Annett,
I’m sorry I didn’t see this until now!
While I’m no expert by any means, I can tell you what I know: I know that often, a direct route is the best way to convey medicine, especially by inhalation for the respiratory system. I also know that there is valid concern that burned plant matter produces by-products that may be carcinogens. The question is whether the benefits outweigh the risks. For me personally, it has. But my use of an herbal cigarette has never been a daily thing, but in a time of acute need.
That being said, there are better ways! You may want to purchase a dry herb vaporizer. You simply load your dry herb into a tiny compartment, where it is heated and the moisture and goodness from the plant matter is extracted and released from the mouthpiece as a vapor, which you inhale as though sucking on a straw. It’s much gentler on the old pipes, your sputum won’t be brown, and it tastes better, more like a tea.
I don’t want to recommend any brands of vaporizer because of spam bots and trolls, but you can do a search. Make sure you specify dry herb. You don’t want the kind for oil cartridges.
