There will be exemptions for legitimate uses of nitrous oxide, for example in medical or catering industries. The gas is commonly used as a painkiller and for producing whipped cream in cooking.
And even better, also legalise drugs like weed which these are being used as a legal substitute for?
Absolutely, although I wouldn’t say NOS is substituted for weed all that much. Also, the legal limit for weed and driving should be raised, particularly since the government asked the scientific community where the level of impairment was and then set it lower.
I’m in favour of legalising drugs, but driving is dangerous and should only be done when you are sober and able to give your full attention.
It’s in no way unfeasible - and the deposits end up paying for the ongoing operation of the system.
Which is better, addressing the littering problem directly, or criminalising and litigating against a bunch of people with a law that can’t be enforced if they have a can of cream on them?
The deposit is just a deposit, it doesn’t pay for anything. Are you sure you understand how the deposit in this case works? You pay for something and you get that back when you return the item.
Maybe you should look into something like the Finnish bottle deposit scheme. It’s great but those take quite some time and effort to set up and get running properly.
