NE: prenatally drug non-exposed adolescents
PDE: prenatal heroin/cocaine exposed adolescents
p values were based on T-test, chi-square or exact test, whichever is appropriate
The p value is 0.035 for 2×2 crosstab between tobacco/alcohol only experimentation (vs. no experimentation of any drug) and PDE, 0.751 for the 2×2 crosstab between marijuana/illegal drug experimentation (vs. no experimentation of any drug) and PDE; 0.815 for the 2×2 crosstab between tobacco/alcohol only experimentation (vs. no experimentation of any drug) and gender, 0.940 for the 2×2 crosstab between marijuana/illegal drug experimentation (vs. no experimentation of any drug) and gender.
