" 5 Botanicals are plant extracts, usually alkaloids, which have
insecticidal properties. Most people believe that since these are "natural"
products, they are " safer" than other pesticides. Many of these chemicals
have not been fully tested and many have striking adverse affects on
mammals. Many cause severe allergic reactions (i.e. pyrethrin and
sabadilla), have high toxicity (nicotine), or are even suspected carcinogens
(nicotine). Examples are:

toxicity and is a suspected carcinogen. "

If that's not enough reason not to use it, tobacco is host to the tobacco
