In my experience (as a mental health worker) drug users of many kinds live in denial of the damage they do, to themselves and others. Those who have escaped catastrophe deny that it could happen. There is a loss of objectivity, which leaves only a blinkered view of their lives. This is as true of alcohol as it is of tobacco and any number of illegal drugs.
In the end it is only public campaign and ultimately legislation that protects the rest of society and preserves its right to be safe from the less mindful. But taking sweets away from children will certainly make them cry 'unfair!', so this is to be expected.
Accusing critics of being patronising or hypocritical is ok for teenagers, but just sounds silly from adults. Address the issue, instead.
Habitual drinkers are not my choice of company, any more than smokers. So I try not to let either spoil my enjoyment of boating, or anything else. I do confess that I find a lovely hot cup of tea both as irresistible as it is refreshing. I am aware of the dangers of caffeine highs, but I wonder if tea has ever been blamed for society's ills. I once scalded my hand on an over-zealous teapot.
