In the Name of Allah, Most Gracious, Most Merciful.

In this fatwa:
Using marijuana or other drugs to relieve pain is permissible subject to certain conditions:
1- That the patient’s need for this drug has reached the level of necessity.
2- That a trustworthy doctor testifies that the drug will be beneficial and helpful for the patient.
3- That use of the drug is limited to the level dictated by necessity.
4- That use of this drug is indicated in the sense that there is no other permissible or less-prohibited medicine that could be used instead.
5- That this drug will not cause the patient any harm that is greater than or equal to the harm for which it is being used; one of the greatest harms to the patient is addiction to using the drug.
Answering your question, the Fatwa Center at Islam Q and A, states:
We ask Allah to grant you healing and well-being, and we ask Him to grant you both reward and a speedy recovery. We advise you to be patient and seek reward with Allah, for the believer is patient at times of hardship and grateful at times of ease.
No doubt you know that Allah is most Wise in what He decrees for His creation of tests and trials, so seek the help of Allah your Lord to relieve you of hardship, and ask Him to make you patient and help you to obey Him and worship Him properly.
Marijuana is a drug that is derived from the cannabis plant. It is also sometimes called hashish or grass.
With regard to the difference between these words, hashish refers to the sticky substance or resin, which is obtained from the tops of the cannabis plants.
Regarding the effects of this drug, it says in Al-Mawsuah Al-Arabiyyah Al-Alamiyyah:
“Marijuana contains more than four hundred chemical substances, and when it is smoked it produces more than two thousand chemical substances which enter the body through the lungs. These chemical substances have a number of immediate, short-term effects, in addition to the fact that regular use is connected to a number of long-term effects.”
With regard to the ruling on using marijuana or other drugs to relieve pain, this is permissible subject to certain conditions:
1- That the patient’s need for this drug has reached the level of necessity.
2- That a trustworthy doctor testifies that the drug will be beneficial and helpful for the patient.
3- That use of the drug is limited to the level dictated by necessity.
4- That use of this drug is indicated in the sense that there is no other permissible or less-prohibited medicine that could be used instead.
5- That this drug will not cause the patient any harm that is greater than or equal to the harm for which it is being used; one of the greatest harms to the patient is addiction to using the drug. (See: Ahkam al-Adwiyah fi’sh-Shariah al-Islamiyyah, by Dr. Hasan al-Fakki, p. 276)
The scholars of the Permanent Committee were asked: What is the ruling on using pethidine or morphine, which are medicines that have an intoxicant effect, in cases of necessity or need?
They replied:
If no other permissible substances are known that could reduce the patient’s pain apart from these two substances, then it is permissible to use either of them to ease pain in cases of necessity, so long as using them will not result in any greater or equal harm, such as addiction to their use.” (Fatawa al-Lajnah ad-Daimah, 25:77-78)
During the eighth conference of the Medical Fiqh Council on the Islamic View on Certain Medical Problems: Haram and Impure Substances in Food and Medicines – which was held in Kuwait, 22-24 Dhu’l-Hijjah 1415 AH/22-24 May 1995 CE – it was stated:
“Intoxicant substances (drugs) are haram and it is not permissible to take them except for the purpose of specific medical treatment, in the amounts prescribed by doctors, and provided that they are pure.”
Almighty Allah knows best.
