Notes.

Analytic sample sizes for the outcomes were n(ever use alcohol)=538, n(ever drunkenness)=557, n(ever use cigarettes)=538, n(ever use marijuana)=557, n(ever use inhalants)=542, and n(ever use hard drugs)=526. Rank order not reported when overall initiation was less than 10%.

†

Expected frequencies for some classes are too small for trustworthy significance testing of the contingency table. Overall and pairwise significance tests are not reported.

a

Value is rank order 1st (high to low) among the five profiles for initiation of that substance.

b

Value is rank order 2nd (high to low) among the five profiles for initiation of that substance.

c

Value is rank order 3rd (high to low) among the five profiles for initiation of that substance.

d

Value is rank order 4th (high to low) among the five profiles for initiation of that substance.

e

Value is rank order 5th (high to low) among the five profiles for initiation of that substance.
