That&#x27;s basically where cigarettes are in the US. Their use is discouraged, there&#x27;s an age restriction on sales, they are heavily taxed, people are educated about the dangers of smoking them and there are nuisance restrictions on public use in many cities.<p>Beyond that, people are free to do as they please with a reasonable expectation that it&#x27;s an informed decision.<p>I think a lot of what we&#x27;re seeing in the US is simple &quot;new market&quot; factor more than anything else. The assumption is that it will settle down at some point once there&#x27;s a reasonably established marketplace.
