What Do Young Adults Expect from the Recreational Use of Ecstasy (3,4-Methylenedioxymethamphetamine/Molly)? A Latent Class Analysis of a Convenience Sample of Dutch Young Adults.

Introduction: This study offers insights into Dutch young people's expected social and personal consequences of ecstasy use. Substance use expectancies are assumed to be an essential component in explaining substance use behaviour and, therefore, the development of effective substance use prevention and treatment strategies.

Method: Dutch young adults with an online interest in drug-related social media posts were targeted with an online survey about their use of alcohol and drugs.

Latent Classes of Substance Use in Young Adults - A Systematic Review.

This systematic review provides an overview of studies on latent classes related to the substance use among young adults (18-25 years). Identifying these classes helps to detect high-risk groups, setting a base for selective prevention. This systematic literature review included peer-reviewed studies (published up to February, 2021) that identified latent classes and investigated predictors of latent classes relating to the use of marijuana, alcohol and/or other substances within samples of young adults.
