The scourge of alcohol

Recently the media have covered many problems triggered by alcohol - abuse: road accidents, brain damage, violence etc. Of course, no-one intends to become an addict but many do for all that. I have yet to meet anyone who seriously regretted not starting to imbibe but have known many who have rued the day when they did start, often because of peer pressure or fear of being regarded as a wowser. Personally I am a total abstainer as a matter of principle and for the sake of example, apart from anything else. (I would hate anyone to follow my example of even moderate drinking and then develop an addiction.) So am I my brother's keeper? To some extent I am - and so are we all.
