I would say that our parents are definitely our first educators, so they're our first line of defence. As with every health issue that we come across, the parental responsibility and role is paramount; it's the number one role. Just as with smoking, gambling, and alcohol, the state also has significant roles to play in that as well.
In Canada we have public health so we need to ensure that everybody is engaged in informed consent so that they know what they're getting into when they view these things. Look at the models that we've done for either tobacco use or alcohol use in terms of how the state has interfered with parental rights.
