本篇研究蒐集美國、加拿大地區為主的研究、文獻以及相關報導並加以整理，分析美加二國大麻產業的歷史演進、除罪化和合法化的過程、政府對於大麻相關的法律條例、大麻產業鏈的現況、大麻產業的風險評估、開放大麻對整體社會的外部性。
與大麻研究者的深度訪談傳達了台灣民眾對於國內外大麻合法化的看法以及開放前後可能遇到之挑戰。藉由文獻分析以及深度訪談法探討被視為二級毒品的大麻，是如何透過國家政府的控管邁向合法化並取得經濟效益，作為未來台灣有可能同樣將大麻除罪化的借鏡。
分析台灣與美加地區的法律差異、毒品盛行率和犯罪率的比較、同為娛樂物質的香菸和酒精的競爭與合作關係，預估台灣開放大麻後之利弊關係以及大麻合法化之可行性。受訪者認為開放大麻合法化能對經濟或是稅收產生效益，但必須配合有效的法律規範以避免負面效果的產生，並於文末提供關於大麻合法化之有效配套措施。

．大麻教育的普及
．法定年齡限制
．制定產品標準規格及價格
．禁止麻駕以及使用場所限制
．鼓勵醫療用大麻相關研究
．打擊非法市場
