Cardiovascular functions and arterial stiffness after JUUL use.

Introduction: The rapid growth in the e-cigarette market after the launch of JUUL e-cigarettes led to much discussion on the potential benefits and risks of pods, JUUL devices, and conventional e-cigarettes compared with combustible cigarettes. Independent data are required to assess the effects of these products on cardiovascular surrogate parameters and cardiovascular risk.

Methods: We conducted a single-center three-arm study comparing combustible cigarettes with JUUL e-cigarettes with the old and new technology.

We Have a Lot to Do: Lack of Sexual Protection and Information-Results of the German-Language Online Survey "Let's Talk About Chemsex".

The prevalence of chemsex and sexualized substance use is increasing in several European countries, particularly among men who have sex with men. In this subgroup, illegal substance use is associated with increased sexual risk behavior, which can result in severe physical and psychological impairments. The present study examined the incidence and prevalence of chemsex in German-speaking countries.

Nicotine delivery and relief of craving after consumption of European JUUL e-cigarettes prior and after pod modification.

The emergence of e-cigarettes on the consumer market led to a tremendous rise in e-cigarette consumption among adolescents in the United States. The success of JUUL and other pod systems was linked to its high nicotine delivery capacity. In compliance with the European Tobacco Product directive, liquid nicotine contents in the European JUUL variants are limited to 20 mg/mL or below.

Background: Recently there has been an increase in reports of the phenomenon called chemsex, a subform of sexualized substance use. Chemsex is a neologism consisting of the two terms "chemicals" and "sex". It describes the use of methamphetamine, γ‑hydroxybutyrate/γ-butyrolactone (GHB/GBL), mephedrone and sometimes other substances in a sexual context, especially by men who have sex with men (MSM).
