Shall we define "Safe"?

I keep seeing it, you keep seeing it - those anti-nicotine who say stupid things like "Yes, ecigs are safer than smoking, but they're not SAFE".

Nothing is safe - really. The word "safe" ALWAYS needs a modifier.

Here's MY point... NOTHING is safe. Nothing. There is no such thing as "safe" in the real world.

Every instance of "safe" needs a modifier - even the definitions to the left there have modifiers - "Safe from marine predators" - but not devoid of all risks. "Not likely to lead to harm or injury" - again, implies zero risk, but the example given, crossing a river where it is "safe to do so" actually DOES involve risk.
So, in truth when we're talking ecigs, and we want to use the word "safe", I think we actually can. They are "safe" ENOUGH to satisfy the generally accepted definitions of "safe".

Is crossing a main road safe? Well, no, not absolutely. It always involves some risk. So, is NOT crossing the road safe? Nope, probably not, as it, too involves some risk (as in a bus, car, whatever may mount the kerb on the side you're on and hit you, so, for all its risks, crossing the road may have been safer in that scenario). So given two possible actions, neither is safe.

Enter the risk assessment. Anyone who has spent any time whatever working in the entertainment industry (or any other that involves folks actually doing things) will have conducted risk assessments. Since it's generally acknowledged that nothing can ever be described as "safe", we now have to assess the risks of doing absolutely everything. And I do mean everything. And then we have to mitigate or minimise those risks.
Guess what ecigs do! Yup - they mitigate and minimise the risks of using nicotine.

AND THEY'RE SAFE ENOUGH. SAFE ENOUGH TO BE CALLED "SAFE". OK?
