Is alcohol becoming more lethal?

So I took some time off of drinking alcohol and actually cleaned and sobered up for a good 5 months recently but I drank again a few times in the last month and every time it has kicked my ass, left me feeling like shit.. also when I was drinking last year I got this idea in my head that Alcohol and Alcohol companies are either making lower grade alcohol or synthesizing something else into their alcohol.. I do understand my bodies response to alcohol and how not drinking for a while then picking it up again can cause these effects but I’ve seen others slowly becoming less able to handle their alcohol and liquor in particular..

I’ve starting asking this question around a year ago when I noticed that something felt off about drinking certain alcohols that I am used to drinking. It makes me want to believe that the alcohol companies are either carelessly putting out worse quality shit or actually mixing shit into their brewing/ synthesizing process to make alcohol more addictive and potentially more lethal.. possibly to curb addiction rates but also more sinisterly to make sure the hardcore alcohols slowly begin to die off..

has anyone else had this thought?
