1468. Is There a Difference Between Khamr and Drugs?
The ‘illah of the prohibition of khamr is sukr, which is best translated as intoxication, yet this is still not entirely accurate. There are consequential differences between the intoxication that results from the consumption of alcoholic beverages and that which results from cocaine, for example. By consensus, all drugs and substances that cause impairment of judgment are forbidden, but many scholars who forbid all such drugs do not necessarily give them the same rulings as khamr; they distinguish between the intoxication that results from them and that which results from alcoholic beverages. Of those scholars are: the Mâliki scholars al-Ḥaṭṭâb and al-Qarâfi, the Shâfi‘i scholar Zakariyâ al-Anṣâri, and others. Their position is backed by the medical differences between the intoxicant effects of alcoholic beverages and drugs.
Most scholars did not differentiate between the intoxication of khamr and that of drugs. Of them are: an-Nawawi, Ibn Taymiyah, Ibn Ḥajar, al-Munoofi al-Mâliki, Ibn ‘Âbideen al-Ḥanafi, and others.
Some practical consequences of this disagreement include: Is the consumption of drugs punishable by ḥadd? Can morphine and other drugs be used for medical indications? If you take the position of the first group, the answer to the first question is no and to the second is yes. Some of the scholars who uphold the position that drugs are just like khamr will still allow their medical use.
