Really it depends on how deep you want to go with the question. You say Drugs or alcohol but what kind of drugs? Are we talking cocaine, marijauna, meth, caffeine, heroin, nicotine, or opiates? Alcohol is self explanatory so i'll not list the thousands of different kinds of beers and whiskeys.
Prior to heart surgery, I liked to have a few beers now and then as well as was a smoker for over 20 years. Post heart surgery, I do not participate in any of my old habits. No beer, no smoking, and def no recreational drugs.
With that being said, I would choose drugs over alcohol as I still like to drink mountain dew and caffeine is technically a drug.
