But surely you jest! Of course, you allude to hashish and opium.
No, the word "alcohol" (like many English words starting with "al") is of Arabic origin.
alright then!
And for the modern day drug sold at every corner a.k.a. coffee
Which contains the alkaloid, caffeine!
The word, yes, but the etymology is more related to the idea of alcohol being an 'essence' of something.
Actually, al-cohol roughly means "the blue", referring to the blue tint of many alcohol-based make-ups used in the Near East in ancient and medieval times.
While on the subject of words with Arabic etymological roots, my personal favourite is Betelgeuse. The Arabic name of the star is يد الجوزاء (yad al-Jauzā) which means "the hand of the Jauzā". But after a few medieval translation it got morphed into it's current name. Which, unfortunately, ended up sounding like, and often back translated as, ابط الجوزاء -- literally "the armpit of the Jauzā"!
