I am almost positive that T rump really doesn’t like alcohol, because his brother was, reportedly, pretty messed up by alcoholism. So T rump reportedly has never touched the stuff. Yet somehow he acts like someone who has had too much to drink. So I think it is a good idea for T rump to NEVER drink alcohol. Too bad for him that he can’t enjoy alcohol like a normal person.
As far as his being against street drugs, that is rather hypocritical if he abuses prescription drugs.
I see no evidence of him abusing prescription drugs. (No, clinically questionable hydroxychloroquine use isn’t drug abuse).
Occasional mispronunciation is not a sign of drug abuse of any sort.
Don’t forget that he said that he also took a powerful antibiotic, arithromycin, when there was no sign that he had a bacterial infection.
Actually occasional slurring of words is often a sign of inebriation. Calling “origins”, “oranges”, repeatedly could be a sign of something else, though.
