This is very interesting. Thank you for posting it. However, after some reading and research

(see point 36)
.......36. THIQs are a cause of alcoholism. This is an old theory,
which was very attractive in the early 1970s. It suggested that
alcoholics, when they drink, form opiate-like THIQs (abbreviation for
several artificially-formed chemicals) in the brain, to which they
become dependent. Later research was not able to consistently find
THIQs in the tissues of alcoholics compared to those of non-alcoholics.
Thus, the “THIQ theory” is no longer popular among most scientists.
I'm not saying there isn't any substance to THIQ, however, it can't be taken as fact.
