Question: What brought about the law prohibiting drug use, alcohol, and opiates in the Islamic Republic of Iran?

Explanation: The question points to 1979, the year of the Iranian Revolution and the establishment of the Islamic Republic, when the new regime reshaped law and public morality and moved to prohibit (or strictly regulate) intoxicants such as alcohol and narcotics as part of an Islamization project. (Course timeline: Iran → Islamic Republic after 1979). Ghiabi_Pluriverse Quote: I did not find an explicit sentence in the PDFs available to me that states (verbatim) “in 1979 a law was issued banning drugs, alcohol, and opiates,” so I can’t honestly attach a direct lecture-quote for this specific wording from the files here.
