Question: What is the textual proof that smoking marijuana is strictly prohibited (haram)?
In the Name of Allah, the Most Merciful and Compassionate.
The Messenger of Allah (Allah bless him and give him peace) said, “Anything that intoxicates in large amounts then a little of it is forbidden (haram).” [Tirmidhi; Abu Dawud]
The Qur’an clearly prohibits wine (khamr). The reason for such a prohibition is understood to be the covering of the intellect. [Jassas, Ahkam al-Qur’an; Ibn ‘Abidin, Radd al-Muhtar]
By extension, the scholars have taken the prohibition applicable to everything that shares the same legal cause, i.e. the covering of the intellect, intoxication. [Ibid.]
I hope this helps,
Allah knows best.
