Neither of those is a medical contradiction to receiving a transplant. Smoking is the big no-no because it is fairly well proven to impair healing and increases chances of failure. Evidence against red meat is very weak, and contradictory. Some studies show no harmful effects from non-processed red meat at all. In fact, there is just as much evidence against plant-based diets (they just aren't discussed widely due to the prevailing politics around CO2 etc), basically it's all just noise. Light alcohol use is absolutely fine in almost every case, and John Hopkins routinely does liver transplants for dependent alcoholics with an alcohol-related liver disease. You should look up some centenarians cases, some lived on a diet of nothing but beer, waffles and blood sausages daily for several decades, and then had a nice healthy liver on autopsy at 100+ y.o., could've been from someone in their 20s. Such is life.
