飲酒最大害處是亂性,酗酒的人通常失去理智,包括醉酒駕
A. You are damn right. Drinking must lead to brain and liver damage, not to mention crime and aggression associated with the disinhibition and impulsivity and those traffic accident. My view is that because majority if not all of us like to have a bit of drink every so often. On the contrary, the majority of us don't smoke. Even without the big money, just playing on the selfish gene, the public tends to be more lenient on alcohol regulation. So, there is no absolute right or wrong ....
Q. 但禁煙的人可能會飲酒.
A. Yeap. Smoking does associate with health issues, it increases the likelihood of different diseases, for example lung cancer (probability).
On the contrary, substance abuse (excessive alcohol consumption is one form) can cause neuronal damage as well as liver cell damage - it is a dosage-effect relationship. But it also depends on whether the individual has certain variant of liver enzyme that can metabolize alcohol faster. A greater proportion of Westerners have more of this "fast" liver alcohol dehydrogenase enzyme, so they can drink more without feeling sick and sustain more long-term harmful effects paradoxically. i.e. those who do not easily get drunk got more health problem usually as they drink more in total (if they have alcohol dependence).
