Abstract Because methamphetamine exposure to experimental animals can damage brain dopamine neurones, we examined whether hospital patients diagnosed with methamphetamine‐related disorders might have greater risk of subsequent admission a Parkinson's disease diagnosis. This was population‐based cohort study using all statewide inpatient discharge records from July 1, 1990, through June 30, 2000, in California, USA, which subjects aged at least 50 years were followed for up 10 years....
Clinical investigators in Japan have long suggested that exposure to methamphetamine might cause a persistent schizophrenia-like psychosis. This possibility is discounted the Western literature. To investigate relationship between drug use and later schizophrenia, authors conducted large-scale cohort study of users initially free psychosis.A population-based was using data from California inpatient hospital discharge records 1990 through 2000.

Our study aimed to address this issue. Methods Drawing upon emergency department (ED) presentations aggregated across Alberta Ontario, Canada records (April 1, 2015–December 31, 2019), we employed Seasonal Autoregressive Integrated Moving Average (SARIMA) models assess associations between Canada's...

However, experimental animal studies indicate that chronic heavy alcohol consumption may have dopamine neurotoxic effects relevant for PD. We studied the association between diagnosed use disorders and All individuals in Sweden admitted a diagnosis of an disorder appendicitis (reference group) January 1, 1972 December 31, 2008 were identified through Swedish National Inpatient Register,...
In 2012, 10% of Canadians used cannabis and just under half those who use were estimated to have driven the influence cannabis. Substantial evidence has accumulated indicate that driving after increases collision risk significantly; however, little is known about extent costs associated with cannabis-related traffic collisions. This study quantifies collisions in Canadian provinces.Province age specific cannabis-attributable fractions (CAFs) calculated for varying severity. The CAFs applied...
ABSTRACT Aims Reducing drug purity is a major, but largely unstudied, goal of suppression. This study examines whether US methamphetamine was impacted by the suppression policy and Canadian precursor chemical regulation. Design Autoregressive integrated moving average (ARIMA)‐intervention time–series analysis. Setting Continental United States Hawaii (1985–May 2005). Interventions federal regulations targeting precursors, ephedrine pseudoephedrine, in forms used large‐scale producers were...
