Note: Md = Marijuana abuse/dependence symptom count; Ad = Alcohol abuse/dependence symptom count; Nd = Nicotine abuse/dependence symptom count. Bold indicates that the observed longitudinal decline is significant.

Note that the genetic, shared environmental, and non-shared environmental contributions are scaled such that summing them provides the phenotypic correlation (except for some rounding error).
