At present, I mail order tubes... papers with filters already attached. They are available locally, but lots more expensive than if I order online.
I am concerned about the dioxin (?) bleach, in the paper, but haven't come up with a better idea as of yet.
Homegrown can be better than commercial or worse. Just like using manure on foods that you will consume raw... it can lead to issues.
If your tobacco is contaminated with mold etc. It can be dangerous too.
Yes, if you leave out toxic chemicals, which I do, and are very particular not to have raw manure on leaves, or wash them good before drying, and don't save any that mold then you can be a bit healthier. It is still tobacco, but without the additives, like antifreeze, and pesticides, and the list is of about 500 items!
There are also herbal items like Mullein or Sumac that you can add to your smoke blend. There are actually smoking cafes that feature herbal blends and no nicotine. Mullein was smoked to relieve chest congestion at one time.
I am considering a "pet tobacco" plant... some times just touching it will give you lots of nicotine, no need to smoke, chew, or dip... just pet the leaf! ha ha Now what could be safer than that? Abstaining, I know, but it is a consideration. So, smoke mullein, and no nicotine, no chemicals, and good for my lungs, and pet the tobacco?
