Many of the people who drank responsibly became alcoholics. The amount of alcohol that is drunk does not completely determine that the person becomes an alcoholic, it is alcoholism that prevents a person from controlling their drinking.

The damage caused by alcohol depends mainly on the amount that is ingested, no matter if it is during the week or only on weekends. In our country there is a large consumption of alcohol on Fridays and Saturdays, this is known as "explosive consumption" which causes road accidents and violence, as well as damage to the liver and brain.

Drinking with a straw causes alcohol to be ingested more quickly than sip by sip, so that the effects of the drink are perceived in less time.
