I cannot create a summary of the requested article because the article titled "Drug injection fades as smoking grows more common, marking sea change in U.S. fentanyl epidemic" is not found in the search results provided. The search results include information about the fentanyl crisis in the US, its classification as a weapon of mass destruction, and overdose death statistics, but not the specific article you asked to summarize. In order to create an accurate and factual summary in accordance with your requirements, I need access to the full text of this particular article.
