Nine
female and 21 male alcohol-free subjects introduced 10 mL of diluted gin (20%
v/v alcohol) into their mouths under two conditions. The subjects either rinsed
the alcohol for 10 s and then expectorated or immediately swallowed. They then
provided breath samples into an Intoxilyzer 5000 at 5 and 10 min postadministration
for both conditions. The mean Intoxilyzer results plus or minus one standard
deviation (n = 30) were 0.091 ± 0.051; 0.036 ± 0.027; 0.014 ±
0.011, and 0.004 ± 0.006 g/210 L for 5 min after rinsing, 5 min after
swallowing, 10 min after rinsing, and 10 min after swallowing, respectively.
The percentages of times that mouth alcohol was correctly detected by the Intoxilyzer
5000 were 90%, 66%, 62% and 30% for these conditions, respectively. Ten minutes
after the introduction of alcohol into the mouth, 63% of the Intoxilyzer results
were > 0.010 g/210L after rinsing compared with only 7% after swallowing.
The mouth alcohol effect is greater for rinsing than for swallowing alcohol. Reproduction
