As stated in the announcement, this decision is in the context of the widespread availability of reduced-harm nicotine delivery devices, namely e-cigarettes. Reducing nicotine levels in conventional cigarettes is hoped to push existing smokers towards e-cigarettes, whilst reducing the appeal and the addictive potential of cigarettes to young people.
I would hope that this decision will be backed up by pilot studies and long-term surveillance, but it seems quite reasonable prima facie.
Yes, this is exactly what will happen as happens with any addictive drug. The solution causes the problem to be worse. The government really needs to get out of the drug war business.
Absolutely not. There is a substantial body of evidence showing that e-cigarette vapor is vastly less carcinogenic than tobacco smoke if the coil temperature is kept below ~220°C. Fortunately, the market is now awash with devices that have accurate temperature control.
The issue of diacetyl was potentially significant, but is now mostly fixed. Reputable manufacturers are aware of the toxicity of diacetyl and have overwhelmingly removed it from their products. Diacetyl is expected to disappear completely from e-cigarette products under the new regulatory regimes in the US and the EU. Cigarette smoke contains far greater concentrations of diacetyl than even the worst e-cigarette products tested.
This announcement by the FDA shows a clear intention to transition current smokers from combustible cigarettes to alternative nicotine delivery systems; this reflects the overwhelming body of evidence for the greatly reduced harms associated with e-cigarettes.

Let's put it this way: are there any scientific studies with results indicating that nicotine, by itself, has significantly stronger self reinforcing properties in comparison to caffeine.
The answer is no: there are none. Quite the opposite. Nicotine has pretty weak self reinforcing properties for all the hype. The magic is in tobacco smoke and various other drug interactions that result in the strong self reinforcing properties of tobacco smoke. So, when many people bring up nicotine's addictive properties they're really talking about tobacco smoke.
There's also the hand-mouth habit, but I digress.
How about we only regulated things which are proven to be harmful?
> Wikipedia summarizes Guillem et al 2005 as "Technically, nicotine is not significantly addictive, as nicotine administered alone does not produce significant reinforcing properties" - the addictiveness coming from MAOIs (eg. Khalil et al 2000, Khalil et al 2006) & possibly other compounds present in tobacco; while there don’t seem to many human studies aside from the Amsterdam et al 2006 review on the observed inhibition in smokers (consistent with the MAOIs playing a role in addiction), there are a number of significant animal studies:

Not to say it's not addictive at all, I'm mildly addicted to nicotine gum, to about the same extent I'm addicted to caffeine (if it's available I'll certainly take it, but if I run out, I'm not rushing to the store to buy more).
Maybe regulation is a good idea.
