Alcool = Al kuhul = al kohl
Drinking alcohol – especially drinking it excessively – has been shown to increase people’s risk of liver disease, high blood pressure, heart failure, several cancers, and other health issues. This has nothing to do with a person’s “energy”, but rather the chemical effects of alcohol on the body.
alcohol derived from the arabic word which now is also the term for eyeliner according to some people, in real alcohol is an english term and the english language is known to be a witchcraft language with double meaning, the english language is made in order to be spoken in the language des oiseaux terms can sound similar phonetically to other terms and as you become what you say and do, it is made on purpose to cast soell into someone's life. People who are part of the satanistic movements or secret societies do believe in karma so they willingly alert their victim before doing harm to them.
The reason is that it comes into English via medieval Latin and later old french. The Arabic term was inherited from medieval Latin translations of early Arabic alchemical texts where the term was applied to the main ore of antimony (stibinite). Stibinite when crushed and then powdered and mixed with water was used to create Kohl eyeliner (amongst other things).
Later the term (now inherited into late medieval french) gets used more generally to refer to powdered substances, and particularly those created by titration / precipitation out of a liquid. Then as alcemical practice evolved it is used for liquid substances gained through boiling down (or distilling). Thus in the 17th to late 18th century it becomes synonymous with "spirit of " or "essence of" (i.e. distilled out of ) and is applied to several substances including "spirit of wine/grape" (i.e. ethanol) which becomes it's main meaning as the other substances are chemically identified or refined.
From about 1850 it's meaning shifts again to a more strict chemical definition for all alcohols (Ethanol, methanol, propanol etc.) i.e. any chemical with an -OH functional group.
This evolution of use and meaning is also where the OP's folk tale comes from - a confusion of the use of the term "spirit" which in English speaking countries is a term applied to drinks with a high alcohol content (e.g. vodka, whiskey, brandy etc) but is also a word applied to "essence of a person" / ghosts / soul etc.
There are some additional factors here as well:
Firstly confusion derived from the Arabic form that evolved in the Moor conquered areas of Spain between 711 and 1492CE (Andalusian Arabic). In Andalusian Arabic al-kohl is corrupted from الكحل to قُحُول which when transliterated into Latin based text sounds very similar to the word "ghoul".
The orientalist movement in Europe (much of which was promoted / funded through the non-conformist christian groups which also founded the anti-alcohol temperance movement) builds on this confusion of terms, and an imperfect understanding of the nature of the Djinn and demons etc. from Islamic scripture. Thus a romanticised "wisdom of the orient" folk tale evolves creating a false association between alcohol and ghouls/demons etc which now persists.
This association is at the end very true
