I disagree that e-cigarettes should be sold only on prescription. I do support the view that they should be sold where the benefits outweigh the risks.
Sir, the comparison between electronic cigarettes and combustion cigarettes is unavoidable. If combustion cigarettes are limited to access only by prescription, then perhaps it may be appropriate to think about similar restrictions on e-cigarettes. But it's perverse in the extreme to believe that a product that is so harmful, that kills half of its long-term users, is widely available and that a product that is a magnitude of difference in risk would be more highly restricted. It's an upside-down logic, sir.
