An update of a systematic review and meta‐analyses exploring flavours in intervention studies of e‐cigarettes for smoking cessation

Addiction, Volume 120, Issue 4, Page 770-778, April 2025.
Abstract Aims To determine patterns of e‐cigarette flavour use (sweet, tobacco, menthol/mint) in interventional studies of e‐cigarettes for stopping smoking, and to estimate associations between flavours and smoking/vaping outcomes. Methods Update of secondary data analyses, including meta‐analyses subgrouped by flavour provision and narrative ...

Nicotine pouches and clinical outcomes related to smoking cessation: A systematic review of randomized trials

Addiction, EarlyView.
Abstract Background and aims Tobacco‐free nicotine pouches (NPs) are oral nicotine products promoted by manufacturers and some researchers as tools that may reduce nicotine cravings and support smoking reduction or cessation. However, evidence regarding their actual clinical impact remains limited.

Associations of cannabis use, tobacco use and co‐use with brain volume: A systematic review and meta‐analysis

Addiction, EarlyView.
Abstract Background and aims Cannabis is the most widely used illicit drug worldwide and is often co‐used with tobacco, the leading cause of preventable death. Although cannabis and tobacco have distinct neurobiological actions, their associations with brain volumes are unclear.

Effects of ZnS Buffer Layer on Performance of CIGS Solar Cell

East European Journal of Physics
Cu(In,Ga)Se2 (CIGS)-based thin-film solar cells are currently among the most efficient. Zinc sulfide (ZnS) is the best buffer layer used in CIGS-based solar cells because it is non-toxic and has a wide band gap.
