FIGURE 2(a). Proporti<strong>on</strong> and number <str<strong>on</strong>g>of</str<strong>on</strong>g> inhalant current users<br />

and new users: Colombia, 1992.<br />

Other results suggest that the mean age <str<strong>on</strong>g>of</str<strong>on</strong>g> initial inhalant use am<strong>on</strong>g<br />

high-income current users was lower than that <str<strong>on</strong>g>of</str<strong>on</strong>g> the middle and lower<br />

income inhalant users: 13.8 years, 17.1 years, and 17 years <str<strong>on</strong>g>of</str<strong>on</strong>g> age,<br />

respectively. It should be noted that these age differences were found to<br />

be statistically significant at p < 0.0004. In additi<strong>on</strong>, those living in cities<br />

with populati<strong>on</strong>s <str<strong>on</strong>g>of</str<strong>on</strong>g> 100 to 500,000 inhabitants initiated inhalant use at an<br />

earlier age than users living in smaller towns or larger metropolitan areas.<br />

This age difference was found to be statistically significant at the<br />

p < 0.000001 (table 11).<br />
