What are side effects of gin?

Same as any alcohol. Less likely to cause hangover, but causes the same liver inflammation, scarring and damage as any other form of alcohol, as well as damage to esophagus, stomach, pancreas. Also can be toxic to the heart, the immune system, the bone marrow (which makes our blood components), impairing our ability to fight infections and our general immune system. PLUS, it causes many kinds of cancers.
