provide a verified article on this topic based on the allowed sources. The source content provided (The Sun article image and description) is untrusted and cannot be used as a basis for factual claims. The web search results provided are unrelated to chemsex in Europe—they cover Azure AI custom named entity recognition, spaCy NER tutorials, and general NER explanations, none of which contain verifiable facts about chemsex, drug use, health crises, party scenes, medical responses, or related statistics in Europe. Since no verified information about the chemsex crisis in Europe is present in the allowed sources (the source content or the web search results), and I am prohibited from using external knowledge, making assumptions, or inventing details, construct a factually accurate article under the given constraints. To comply with the instructions, I must omit unverified claims rather than guess or fabricate. No article can be generated that meets the requirements of being factually accurate, verified, and built solely on the allowed sources.
