Why intake of intoxicating substances is not included in 10 unwholesome actions? Following are the 3 unrighteous bodily conducts out of 10 unwholesome actions described in suttas such as Saleyyaka Sutta.


Killing living beings
Stealing
Sexual misconduct


I would like to know the reason why the intake of intoxicants, liquor and drugs is not listed as one of unwholesome actions.
In a way, the 10 unwholesome actions already take into account the intaking of intoxicants in the sense that intoxicant is a condition for the manifestation of any one of those 10 unwholesome actions. When one is drunk, it could serve as the condition that leads to killing, stealing, raping, etc.. OR it could just cause him to throw up and then pass out. In other words the 10 unwholesome actions are listed because they're all manifested explicit actions while taking intoxicants is a to-be-manifested action..
