If you work from home, via the internet for instance, then your home is a "workplace" and as from July 1st you will need to display a "no smoking" sign outside your front door and you must not smoke in your workplace.

You might wonder how the government will know if you are smoking in your workplace. Well that is where the new government smoke detectors will come in - possibly linked with a webcam. These will come at a cost to the "workplace" owner of around £80+VAT.

This isn't overly intrusive because if you aren't doing anything wrong then you have nothing to hide.

Okay I made it up. But give it a year or so.
