This paper conducts GWAS on cannabis use frequency and lifetime use, identifies genetic loci, and shows genetic correlations with other traits and diseases.

This study investigates the polygenic relationship between cannabis use and schizophrenia using data from the All of Us Research Program, finding independent associations between polygenic scores for cannabis use disorder and schizophrenia.

This study identifies 14 genome-wide significant loci for delay discounting in 134,935 individuals and shows genetic associations with 212 medical conditions.

The paper identifies shared molecular networks between common and rare variants associated with alcohol consumption, revealing genes involved in alcohol metabolism and comorbid psychiatric traits.

This study compares GWAS results of coffee intake from 23andMe and UK Biobank, finding discrepancies in genetic correlations with health traits and highlighting cultural differences in gene-cohort influences.

This study performs a multi-ancestry meta-analysis of tobacco use disorder using electronic health records, identifying 88 risk loci and 461 potential risk genes, and linking TUD to various health outcomes.
