Home made nitrous injection

[Waterboard]

I’ve been thinking about making a manual nitrous oxide injector using the valve assembly from a whipped cream maker.
The plan would be to run the feed from inside the car via a door mounted trigger directly to a nozzle just after the throttle body.
The only way I could control the delivery would be with using something like a carburettor main or pilot jet as a crude calibration method.

What could go wrong

Hi.
I was wondering with the government planning on banning the sale of nitrous oxide does that mean it would be unavailable for car owners.
