Opium poppy cultivation and poppy straw production form key topics in pharmacognosy and pharmaceutical raw-material supply chains. This introduction reviews agronomy, harvest timing, processing of poppy straw, major opiate alkaloids (morphine, codeine, thebaine), and quality-control principles relevant to B. Pharm students. Emphasis is placed on cultivation factors, legal and regulatory frameworks, alkaloid distribution in plant parts, industrial poppy-straw processing versus traditional opium collection, and analytical methods used to quantify alkaloids. Understanding these concepts helps pharmacists appreciate supply, safety, and quality issues in opioid raw materials and downstream drug manufacturing. Now let’s test your knowledge with 30 MCQs on this topic.
