Drunkenness and Regretted Online Social Risk Behaviors: The Role of Social Drinking Motives and Positive Urgency.

Alcohol use and the use of social media and other forms of digital communications is characteristic of young adults. The present study prospectively examined the relationship between social drinking motives and positive urgency and the engagement in regretted online social risk behaviors while drunk (having posted on social media, called or texted someone, or been visibly drunk in a photo) among a community sample of young adults. : Using a targeted sampling procedure, we accessed a baseline sample of 360 young adults aged 18-25 years old from the community.

Changes in Alcohol Use during the COVID-19 Pandemic among Young Adults: The Prospective Effect of Anxiety and Depression.

Health measures instantiated to reduce the spread of COVID-19 have imposed significant constraints for the population and impacted on drinking habits and mental health. This study longitudinally compared changes in alcohol consumption before and after the COVID-19 outbreak and the impact of sociodemographic and mental health variables on such changes among a community sample of young adults. Data were collected in the context of a larger, ongoing longitudinal study.

Harm Reduction Strategies and Drug-Related Negative Consequences in the Dance Music Scene: The Moderating Role of Polysubstance Use.

Although simultaneous polysubstance use (SPU) is associated with greater harms than concurrent polysubstance use (CPU), no previous research has examined the effectiveness of harm reduction strategies in reducing drug-related harms in people who use drugs simultaneously and whether these strategies have a differential impact on drug-related negative consequences according to SPU patterns. to examine the relationship between SPU patterns, harm reduction strategies and drug-related consequences experienced among people who attend dance music settings, and to examine the moderating role of SPU patterns in the relationship between harm reduction strategies and drug-related negative consequences a web-based survey was used to gather data from 649 substance-using attendees at dance music settings (mean age = 26.2, 68% male).

Patterns of Simultaneous Polysubstance Use among Partygoers: Correlates and Differences in Adverse Acute Effects Experienced.

This study identifies patterns of simultaneous polysubstance use (SPU) in partygoers, their associated characteristics, and their differences in terms of acute effects experienced. We used a web-based survey with 1345 partygoers who reported using at least one substance during the past year, collecting information on drug use and drug-related acute effects experienced at the last party attended. Latent class analysis identified three SPU profiles according to the use of nine substances: (67.

Crystals and tablets in the Spanish ecstasy market 2000-2014: Are they the same or different in terms of purity and adulteration?

Background: Although 3,4-methylenedioxymethamphetamine (MDMA) has a long history in recreational settings, research on its composition (purity and adulteration) has focused only on tablets even though crystal format is readily available for users.

Methods: Drug specimens collected between January 2000 and December 2014 were analyzed at Energy Control's facilities. All samples were voluntarily provided by drug users.

Reliability, convergent and structural validity and cut-off score of the Severity of Dependence Scale for recreational ketamine users.

Background And Aims: There is a lack of instruments for measuring ketamine substance use disorders. The aims were (i) to estimate the reliability and provide evidence of validity of the Severity of Dependence Scale (SDS) in a sample of recreational users, and (ii) propose a cut-off point to determine the presence of dependence.

Methods: We conducted a web-based cross-sectional survey with recreational users who accessed webs related to recreational drug use and harm reduction.

Patterns of use, harm reduction strategies, and their relation to risk behavior and harm in recreational ketamine users.

Background: Recent studies have shown that ketamine use has serious adverse consequences. However, no studies have focused on the strategies that users carry out to protect themselves from such potential harm.

Objectives: (i) analyze harm reduction strategies, risk behaviors, and harms in nonmedical/recreational ketamine users; (ii) analyze the association of their harm reduction strategies and risk behaviors with harms they report.

Harm reduction behaviors among young polysubstance users at raves.

Background: Raves may be considered recreational settings in which drug use and health risks related to polydrug use are higher than in others. Harm reduction behaviors implemented by ravers are of particular relevance in reducing such risks. This study analyzes harm reduction behaviors and their relationship to raver polysubstance use patterns.

New psychoactive substances as adulterants of controlled drugs. A worrying phenomenon?

The use of new psychoactive substances (NPS) as adulterants has received little attention in the literature. In this paper, results from Energy Control's drug checking service documenting the use of NPS as adulterants of controlled drugs are presented, and some reflections about possible explanations for this new phenomenon, potential risks for users, and challenges that it poses are discussed. From 2009 to 2012, 24 NPS belonging to several chemical classes such as phenethylamines, substituted cathinones, tryptamines, and methoxetamine were identified in 173 samples believed to be MDMA, amphetamine, ketamine, cocaine, mescaline, or methamphetamine.
