Lobelia - what's the use in it?

[kryptik]

swim has always wondered about Lobelia. swim has heard it's just tobacco, or indian tobacco.. but for some reason, it shows up in urine tests... why? if it's just tobacco, unless is there something else in it? is there a high to be achieved off it?

Lobelia inflata is not tobacco. It's another plant, also called "indian tobacco." See the Ethnobotanicals forum.
