You can die of cirrhosis from drinking too much for too long, but it's still culturally held as a stress reliever. You can die from diabetes if you eat too much sugar for too long, but it's still sold to children as edible happiness. Hell, you can die slowly and painfully from taking too much Tylenol, but it's still the world's most popular painkiller by far.
Too much of anything kills eventually. That doesn't bare any significance to whether or not it's good for stress in some amount.
