TL;DR: Those who had ever used e-cigarettes at baseline compared with nonusers were more likely to report initiation of combustible tobacco use over the next year, and further research is needed to understand whether this association may be causal.

TL;DR: This study identifies a novel locus for neuroticism located in a known gene that has been associated with bipolar disorder and schizophrenia in previous studies and shows that neuroticism is influenced by many genetic variants of small effect that are either common or tagged by common variants.
Journal ArticleDOI

Adam M. Leventhal,David R. Strong,Steve Sussman,Matthew G. Kirkpatrick,Jennifer B. Unger,Jessica L. Barrington-Trimis,Janet Audrain-McGovern +6 more
TL;DR: Questions of whether emotionally-healthier ('lower-risk') adolescents who are not interested in conventional cigarettes are being attracted to e-cigarettes are raised and research, intervention, and policy dedicated to adolescent tobacco-psychiatric comorbidity should distinguish conventional cigarette, e-cigarette, and dual use are indicated.

TL;DR: A large meta-analysis of GWA studies for extraversion in 63,030 subjects in 29 cohorts shows that extraversion is a highly polygenic personality trait, with an architecture possibly different from other complex human traits, including other personality traits.
Journal ArticleDOI
Acute Physiological and Behavioral Effects of Intranasal Methamphetamine in Humans
Carl L. Hart,Erik W. Gunderson,Audrey Perez,Matthew G. Kirkpatrick,Andrew Thurmond,Sandra D. Comer,Richard W. Foltin +6 more
TL;DR: Results show that intranasal methamphetamine produced predictable effects on multiple behavioral and physiological measures before peak plasma levels were observed, which might have important implications for potential toxicity after repeated doses.
