The young Muslims of today are facing an ever-increasing number of plights, one of the most important of which is drugs. But, what is Islam’s view on this issue? How should Muslims regard drugs? To know this, we must see what the Quran and the prophet’s and Imams’ conducts (Sirah) say regarding narcotics.

Since drugs were not known at the advent of Islam, therefore we cannot see any direct evidence in the Sirah on this issue throughout history; so the only way is referring to general rules and principles of jurisprudence.

In general, it has been indicated, firstly, that since drug consuming inflicts tremendous losses, it is considered as forbidden (Haram), unless medical emergencies and necessities require it. Secondly, buying and selling it, is forbidden except where rational, lawful benefits are received, such as medicine production. This form of usage must be under precise official supervision and control. Based on these facts, Muslim scholars hammered out four rational and crystal clear reasons for the forbiddance of drug consumption:

1. All Intoxicants Are Unlawful

All intoxicants are regarded as forbidden because of their inebriant repercussions, as well as their physical-mental adverse effects on individuals and communities. Moreover, drug consumption causes moral degeneration, body and intellect corruption, inflicts severe cultural, social and economic losses and finally ruins societies.

Someone who suffers drug addiction is not able to oversee his behavior, loses his zeal, motivation and common sense, and as a result is ready to do anything to obtain drugs without any consideration. A Drug-addicted person, also, cannot fully adhere to his Islamic practices, since drugs turn him into an irresponsible and a total inefficacious human.

2. The Method of the Wise

Wise men throughout history always avoided using drugs and this attitude is entirely in line with the Islamic law (Shari’a). Following in the footsteps of great personalities and considering their lifestyle is an authoritative way and a logical ground to reason against drug consumption.

3. “No Harming, nor Reciprocating Harm”

This rule is one the most important and fundamental jurisprudential rules which is applied to a wide range of Islamic teachings. On this basis, people should not engage in deeds that inflict excessive losses. Today, we can say from experience that drug consumption encompasses significant social and individual damages and creates completely irresponsible generations. Accordingly, the rule of “No harming nor reciprocating harm” can provide us with the most rational ground to argue against drug consumption; its adverse effects are not only directed to the drug-addicted person himself/herself but also his/her family, relatives and even the whole society.

Furthermore, drug addiction is one of the most significant causes of self-destructing and life-ruining behaviors. We have a clear affirmation about this reality as Allah Almighty says: “and do not cast yourselves with your own hands into destruction” (2:195).

4. Lawfulness of Good Things and Prohibition of Vicious Ones

In Islam, every evil thing which results in heavy losses is forbidden (Haram); clearly, the drug with its many negative effects on a broad spectrum of people is categorized as highly harmful. There is a vivid indication on this claim in the Holy Quran: “He makes lawful to them all the good things and forbids them from all vicious things” (7:157).

The weakness in wisdom and perception power can be considered among the most important disadvantages of drug consumption; therefore, Islam names “common sense preservation” as the most important obligation for a Muslim. Now it is easy to understand why the Islamic law (Shari’a) bans all sorts of intoxicants like alcohol, drugs, etc.

It is noteworthy that based on the first-ever report on worldwide addiction statistics released by researchers, which uses data from sources including the World Health Organization and the United Nations Office on Drugs and Crime, drug addiction has reached epidemic levels across the globe and there were 230 million drug users worldwide in 2015. The report found that drug takes a higher toll on “productive years of life lost” than does any other intoxicant. That means people dependent on drugs not only die younger but also have poor health over a more extended period. Drugs affect their work, relationships, and consequently reduce their quality of life [1].

These results prove how far Islam predicts the disadvantages of using drugs and why it is declared as forbidden (Haram) on almost all of the Islamic decrees.
