Drinking to much?

So what would everyone consider as drinking to much? I dont drink during the week but on a Friday night I enjoy having a few drinks sometimes beer sometimes pre mixed spirits, but its usually anywhere from 8 to 15 cans. I am only 25 and am worried if I keep this up It’ll affect my long term health, I know not drinking is obviously the best option but where I live it is such a normal thing. I dont do any other drugs or smoke so 🤷
