Age Limits and Smoking
I have tended to have "non standard" views on age limits. I don't have a problem where there are different age limits for differing things. When the age of majority was changed from 21 to 18 this affected not only the right to vote, but also the age at which someone could enter into a binding contract. Specifically the issue of obtaining credit is something that I would not wish to make easier at an earlier age.
Whilst otherwise the case is being argued for say a reduction in the voting age it is odd that there is an argument to increase the age at which people can buy tobacco. There is an issue in principle which is the question as to what age such purchases should be allowed. I don't think the case has been made for this to be increased. At the same time there is a practical issue in that it is unlikely to have any effect on the availability of tobacco as there are many under 16s who already smoke.
It will be an interesting debate to square with all the other approaches on age limits.
