Mullein, raspberry leaf, lots of other herbs can be a decent alternative that don't satiate the physical craving. Mullein helps clear out your lungs and can actually help you quit nicotine. You can also cut tobacco with these kinds of herbs. I'd recommend researching herbal smoke blends to anyone interested. Can also be used as a safer alternative if you want to cut your spliffs with something other than tobacco.

Maybe drinking it as an expectorant tea, but I can't imagine smoking it would be helpful overall.
