Indian-Tobacco

Indian-Tobacco
Lobelia inflata

As you might guess, Indian-Tobacco was smoked by Indians.  Native Americans used it for a variety of medicinal reasons, some of which involved smoking, such as a treatment for asthma.  It was also used as a ceremonial plant, i.e. used by shamans and others to cure people during a ceremony.  Sometimes these ceremonies involve hallucinogenic plants, but I think Indian-Tobacco only caused a feeling of goodwill, similar to nicotine.

However, consuming this plant has a variety of side effects, ranging from excessive sweating to death, and lots of options in between.  Do not smoke or eat this plant unless you get clear advice from a medicinal herbalist!

The flowers and seedpods are quite distinctive looking.
