Aim Twin studies have shown that cannabis use disorders (abuse/dependence) are highly
heritable. This review aims to:(i) review existing linkage studies of cannabis use disorders …

Context Despite accumulating evidence that there is a genetic basis for cannabis use
disorders (ie, abuse and dependence), few studies have identified genomic regions that …

Despite moderate heritability, only one study has identified genome-wide significant loci for
cannabis-related phenotypes. We conducted meta-analyses of genome-wide association …

Aims To review three key and controversial comorbidities of cannabis use—other illicit drug
use, psychosis and depression, as well as suicide, from a genetically informed perspective …

BACKGROUND: A genetic contribution to cannabis dependence (CaD) has been
established but susceptibility genes for CaD remain largely unknown. METHODS: We …

Background Cannabis is a commonly used drug and studies have shown that a significant
portion of the variation in cannabis use disorders (CUDs) is heritable. Five genes known to …

While there is solid evidence that cannabis use is heritable, attempts to identify genetic
influences at the molecular level have yielded mixed results. Here, a large twin family …

Background With the increase in cannabis use rates, cannabis use disorder is being
reported as one of the most common drug use disorders globally. Cannabis use has several …

Despite twin studies showing that 50–70% of variation in DSMIV cannabis dependence is
attributable to heritable influences, little is known of specific genotypes that influence …

Aims The genetic etiology of cannabis use, abuse and dependence has elicited significant
interest from genetic epidemiologists. Methods Genetically informative studies, including …
