Yes, all organisms produce alcohol as a by-product of other chemical reactions.  Humans who drink excess alcohol risk problems like liver failure, addiction, and other diseases.  As a general rule, drinking three glasses of wine a day is a safe and responsible amount for most adults, while drinking excess amounts can cause long-term health issues.
