Table 4.

Odds Ratio of subtype drug experimentation (experimentation with tobacco or alcohol only, and experimentation with marijuana and other illegal drugs, separately) in relation to prenatal heroin/cocaine exposure (PDE), behavioral problems and gender based on two separate logistic regression models.

	Experimentation with tobacco and/or alcohol only* (n=92)						Experimentation with marijuana and/or other illegal drugs* (n=109)

^*Experimentation with subtype drug experimentation was compared to abstinence from using any drug.

^**aOR: Odds Ratio of drug experimentation after adjusting for other variables in same column as well as age, perceived peer drug use, current caregiver drug use, prenatal tobacco exposure, and prenatal alcohol exposure. aORs for internalizing or externalizing problems refers to Odds Ratio related to 1 SD increase in the scores.
