Is smoking marijuana haraam?

Question

While there's controversy about whether marijuana causes long term effects, let's assume that the long term damage is no different than eating fatty foods or sugary drinks. It's clearly less harmful than smoking tobacco, so it does not fall under the exact same legality.

Marijuana acts more as a hallucinogen and sedative, but I can't find anything that explicitly forbids those. I'm thinking it may be forbidden as an intoxicant, but it is a different form of intoxication than alcohol.

Answer 1

An intoxicant is defined, for legal purposes in Islam, as anything that dulls the senses and induces a state of mental fogginess (e.g. to the point where one is unaware of what one does). For example, one such principle is mentioned in the following narration from `Umar (ra)

وَالْخَمْرُ مَا خَامَرَ الْعَقْلَ

And khamr is what confuses and stupefies the mind

Source

By qiyas (analogy) to other kinds of khamr, the scholars have declared cannabis/hemp/marijuana haram (prohibited and sinful).

There is no point in arguing about the effects of marijuana on the mind - the effects of THC are well-documented.
