I do not know your friends, but I am 100% sure that they are wrong and it is only suicidal.
If you are an adult 2 to 3 drinks, 2 to 3 times or 500 ml beer or 180 ml wine are the limit for a week. This is called social drinking. The women, if they want, could drink half the amount. It is because a woman’s body could absorb the alcohol quickly, but excretes only slowly. If a woman drinks like a man she could lose all her inhibitions quickly and the result is known to everybody.

Alcohol is not essential for our body. 1 g alcohol has 9 calories which are empty calories.
