1. In oduc ion
Global consump ion o alcohol pe capi a in 2016 was on a e age 19.4 li es o males and 7.0 li es o emales,
con ibu ing o h ee million dea hs annually [1][3]. In he UK, he annual consump ion a e is o e 10 li es [2].
Conside ed a social and physical “global bu den”, alcohol consump ion is ela ed o mul iple diseases, suicides, ehicle
dea hs, disabili y, and psychological diso de s like dep ession and s ess [4] [5].
1.1. His o y o he disease and ea men
The pa hology o alcoholism has been a sou ce o in e es e en be o e No man Ke , ounde o Socie y o he S udy o
Ineb ia es in 1884, decla ed d unkenness was a disease, “a na u al p oduc o a dep a ed, debili ies o de ec i e ne ous

Sho ly a e he Uni ed S a es ended p ohibi ion in 1933, wo men om Ohio ounded Alcoholics Anonymous (AA), a
12-s ep p og am o cha ac e de elopmen o indi iduals o ‘admi powe lessness o e hei addic ion and commi o

Since he ounding o AA, he 12-S ep app oach has been seen as he gold s anda d ea men o Alcohol Use Diso de
(AUD). Due o he na u e o AA being “anonymous”, he e is li le eliable s a is ical da a. Va ious epo s om non-
clinical membe ship su eys pe o med by AA, addic ion specialis s claim sob ie y success a es om 8% o 24% a 1-
5 yea s [8][9].
In addi ion o a emp s a social empe ance and suppo ea men op ions, he medical models o ea men o AUD
ha e included pha macological and beha iou al ea men op ions. E en go e nmen al policies ha e been c ea ed o

1.2. The holis ic app oach
The holis ic app oach is de i ed om he philosophy o humanism and mu ual unde s anding o a pa ien ’s physical,
emo ional, psychological, and spi i ual dimensions. I en ails a close ela ionship be ween pa ien and p o ide o

1.3. Gene ic and neu obiological esea ch
Since he e a o Jellinek’s s udies, he e has been much esea ch in o a gene ic p edisposi ion o alcoholism. Se e al
gene ic ac o s and a ian s ha e been iden i ied ha sugges a isk o addic ion ai s. None heless, alcohol
dependence is conside ed a complex disease whe e inhe i ance is only one pa o he ae iology, and bo h en i onmen al
and social ac o s seem o weigh on he ou come [14].
Genes ADH1B and ALDH2 ha e been ound o a ec he me hods o alcohol me abolism and show he la ges isk o
dependency. Ca alysed p ima ily by ADH, e hanol me abolism begins wi h oxida ion o ace aldehyde and once
accumula ed, he esul s a e dizziness, nausea, and achyca dia. Indi iduals ha ca y a single copy o he ALDH2*504K
gene ha e his eac ion o he ex eme wi h small amoun s o alcohol, ac ing as a de e en o d ink excessi ely [14].
Con inued s udies on he gene ics o alcohol dependence link low cen al se o onin u no e a es as ma ke s o ea ly-

GABAe gic neu o ansmission, he cause o seizu es and au onomic dys egula ion displayed du ing abs inence. Alcohol
c a ing has been explained by he dopamine gic ewa d sys em and opioide gic s imula ion due o posi i ely-

1.4. Mode n ad ances wi h pha maco he apy
Conside ing AUD as a disease and no only a beha iou al issue, esea che s ha e examined enhanced ea men wi h

2. Discussion
The e is signi ican e idence ha he Sinclai Me hod has no able bene i s o use in AUD and should be conside ed a

Whils he e is no sho age o da a and es imonials p aising his “mi acle d ug”, he e is less esea ch ega ding hose
