Average Values for Nicotine, pH, and Free-Base Nicotine in Various Types of Tobacco Used to Prepare Iq’mik

	Air-cured leaf tobacco (n = 3)	Air-cured twist tobacco (n = 3)	Fire-cured leaf tobacco (n = 3)	Fire-cured twist tobacco (n = 6)
Nicotine (mg/g)	38.0 (0.4)	38.5 (8.8)	42.7 (5.6)	35.0 (3.2)
Nicotine (mg) per	9.9 (0.1)	10.0 (2.3)	11.1 (1.5)	9.1 (0.8)
pH 0.26 g serving	11.0	11.0	11.0	11.0
Percent free base nicotine (%)	99.9	99.9	99.9	99.9
Unionized nicotine (mg) per 0.26 g serving	9.9 (0.1)	10.0 (2.3)	11.1 (1.5)	9.1 (0.8)
Unionized nicotine (mg/g)	38.0 (0.4)	38.5 (8.8)	42.7 (5.6)	35.0 (3.2)

Note. Standard deviations are given within parentheses. U.S. moist stuff averages (for comparison): nicotine = 11.9 mg/g; nicotine per 1.2 g serving = 14.3 mg; pH = 7.6; percent free base nicotine = 31.6%; unionized nicotine per 1.2 g serving = 4.5 mg; unionized nicotine = 3.8 mg/g.

The value for pH is based on a mixture of the various tobaccos with punk ash. Values for U.S. moist snuff (n = 39) are included for comparison.
