Social media nicotine markets: Criminogenic affordances and market displacements.

Unlabelled: Illicit drug markets continuously evolve in response to legal regulations, and digitalmarkets similarly adapt, balancing the convenience of online contact with the security of offline transactions. The regulation of nicotine products follows a similar trajectory. In Denmark, efforts to curb youth nicotine consumption have led to legislation targetingsingle-use flavoured vape products, in turn leading to the emergence of illicit social media-based nicotine markets.

Peer-delivered mail-order self-collection and linkage to treatment for hepatitis C virus infection among users of a harm reduction service in Denmark.

Background: Hepatitis C virus infection remains a major public health challenge, particularly among people who inject drugs. Despite the availability of highly effective direct-acting antiviral treatment, many remain undiagnosed and untreated. Self-collection for hepatitis C may improve testing uptake in this marginalized population.

Dried blood spot: A diagnostic detection method for HBV, HCV and HIV nucleic acid using a single drop of blood.

The global strategy to eradicate Hepatitis B (HBV), Hepatitis C (HCV), and HIV by 2030 is critical due to their impact and challenges to healthcare systems. HCV is curable, but HBV and HIV are only suppressible, with a vaccine available solely for HBV. Innovative diagnostic methods are needed, especially for high-risk populations like people who inject drugs (PWID).

Peer-delivered point-of-care testing and linkage to treatment for hepatitis C virus infection among marginalized populations through a mobile clinic in Copenhagen, Denmark.

Background: Globally, many people with hepatitis C virus (HCV) infection are marginalized and have very limited access to traditional healthcare services, including HCV testing and treatment. Models of care attuned to the needs of the marginalized population at risk are needed. This study aimed to evaluate the testing and treatment uptake of a community-based, peer-led model of care offering point-of-care testing.

Effects of self-control, drug-use peers and family attachment on drug use among Chinese users: A gender-specific analysis.
