Identification of nicotine by gas chromatography/mass spectroscopy analysis of smoking pipe residue

Ethnographic sources show the spiritual importance of tobacco in Native American Societies. Archaeological evidence, such as Early Woodland Period smoking pipes, indicate that this spiritual function has been maintained for thousands of years. However, ethnobotanical research on the prehistory of tobacco smoking in Eastern North America has been hampered by a lack of direct evidence prior to the Middle Woodland Period. Research involving a gas chromatographic/mass spectrographic technique (GC/MS) addresses the problem of identifying tobacco through the analysis of pipe residue. Results point to a possible Early Woodland Period use of tobacco in the Eastern Woodlands.
