Interesting results as tbh I expected a larger number of people to say yes.
I wonder if that is because there are a good proportion of posters under 18 on here?
In a forum which tends to attract a considerable number of people who are richer, better educated and/or older than average forum users, the number of people who said they don't use alcohol is the same as the number of people who diagnosed themselves as abusing it - 12.5%. A potent, highly toxic recreational drug routinely abused by a sizeable minority on here, where the proportion of drug abusers is likely to be lower than in society in general.
Interesting results indeed and you raise a good question regarding what effect the proportion of people who are under 18 has. There are probably significantly more >18s who abuse the drug than there are >18s who don't use it at all and that's in this forum.
We have a pretty serious drug problem in this country. It's possible to use alcohol in a way that doesn't cause problems for society and which doesn't damage the user, but a lot of people don't use it that way.
