Most alcoholics and by most I’m referring to 99.99% cannot drink again without issue. There is a phrase in recovery communities regarding this, “ once you turn a cucumber into a pickle, you can’t turn the pickle back to a cucumber.”

After years of alcohol abuse the brain is rewired and it becomes sensitive to alcohol. It only takes one sip for some folks to go right back to heavy drinking and old behaviors.

If your son is an alcoholic (and it sounds like he is) then he most certainly cannot safely consume alcohol.
