Herbs for smoking (fun)

First things first: I’m not interested in getting high, which is why I’m asking instead of reading other posts for an answer

I’ve got some friends who were interested in trying smoking herbs, but I only smoke mullein at the moment. I’ve tried a few other herbs, but I’m not sure where I’d get kinikanik at this time of the year where I live, so right now I’m trying to remember what other herbs my herbalism teacher recommended and get a list of some other options. These friends smoke to get high usually, but, like I said, that’s not the types of herbs I’m bringing.

I have a pretty decent selection of herbs, somewhere in the range of 50-60 different ones. I make my own tea blends to avoid allergens and do some herbalism as a hobby.

Current list (everything is either wild harvested or culinary grade): fireweed, sage, wild mint (I think spearmint), lavender, chamomile, mullein

I’m not opposed to ones that’ll get you high, but I’m mostly looking at herbs that have fun tastes. Debating if I want to share my small pearly everlasting stash too, but I’m not offering it this week at least.
