Yes. Substances that intoxicate or cloud the mind, such as narcotics, fall under the ruling of khamr because they share its reason: they take away the mind and cause harm. The Quran also warns against destroying oneself (4:29).
مومنو! ایک دوسرے کا مال ناحق نہ کھاؤ ہاں اگر آپس کی رضامندی سے تجارت کا لین دین ہو (اور اس سے مالی فائدہ حاصل ہو جائے تو وہ جائز ہے) اور اپنے آپ کو ہلاک نہ کرو کچھ شک نہیں کہ خدا تم پر مہربان ہے
Hadith
