Recent years have brought substantial progress in understanding the genetic etiology of psychiatric disorders, substance use traits, and substance use disorders (SUDs)(1, 2, 3, 4). Genome-wide association studies (GWASs) have benefited greatly from large-scale datasets generated across international consortia and mega-biobanks allowing for well-powered GWASs of many psychiatric and substance use traits. These efforts have resulted in the discovery of thousands of genetic loci that influence these traits, have helped researchers understand the genetic architecture and polygenicity across disorders, and have informed our knowledge of patterns of shared genetic influences—largely through the application of global genetic correlation approaches (1, 2, 3, 4).Approaches for estimating the genetic correlation between traits are often deployed using the output of GWAS analyses—GWAS summary statistics—for the specified traits of interest. Genetic correlation analyses use methodological approaches such as linkage disequilibrium (LD) score regression (5) to generate estimates of global genetic correlation (global r g) that provide information on the amount of overall genetic correlation between traits. Global genetic correlations of substance use compared with SUDs with respect to the same substances—for example, alcohol use versus dependence—have shown that these respective traits differ in their relationship with psychiatric disorders (1, 2, 3). SUDs tend to show positive correlations with forms of psychopathology, while measures of quantity or frequency of substance use (often in the absence of substance use problems) tend to show negative or no genetic correlations with psychiatric conditions (1, 2, 3). While informative, the level of information that can be inferred from global genetic correlations about the shared genetics and the biological mechanisms in common between traits is limited.
