IS THERE AN EPIDEMIOLOGICAL PARADOX FOR ILLICIT DRUGS?

Is there heterogeneity among syndromes of substance use disorder for illicit drugs?

The use of DSM criteria to evaluate liability to substance use disorders (SUDs) and to identify SUD phenotypes may not provide the sensitivity required to identify genes associated with vulnerability to SUDs. The purpose of this study is to evaluate a number of basic aspects of substance use that may be more proximal than full SUDs to risk genes, some of which may thus have greater potential ut...

These claims are incorrect. As I will show here, there is no paradox of logical validity. In additi...
