Is it permissible to study medicine in the United Kingdom given the issue of using certain medications, such as morphine for severe pain relief, anti-anxiety medications that may cause intoxication, and medications containing gelatin for which there is no alternative?

It is permissible to use morphine to alleviate pain when necessary, that is, pain that is unbearable and for which no permissible painkiller exists. As for other intoxicating substances, they may not be used except when necessary and under specific conditions: that the need reaches the level of necessity, a trustworthy doctor's certification, limiting use to the necessary amount, the absence of a permissible alternative, and that it does not cause greater harm.

As for gelatin in medicine, there is a detailed explanation: if it was impermissible and transformed into another substance or was present in a small, consumed proportion, then there is no objection. Otherwise, it is not permissible except in extreme necessity if no alternative is available. Ultimately, studying medicine and practicing it is permissible and commendable, while avoiding شرعية prohibitions.
