Advice on poisons that aren't SN or SA

[LostSoul1609]

I can't easily acquire them so I'm thinking about considering other options, I already have the Night-Night method as a plan B but I'd like a poison for my plan A.
What are the easiest to acquire poisons?

There would be some that could probably be easily obtained but far from peaceful or painless.

Beggers can't be choosers I guess

How about inert gas options like nitrogen or helium ? They can be bought easily in most countries in the world, the seller usually doesn't give a shit what's your usage.

What about the mask tho? I would need to use one to assure I get enough to die.
Would also be safe to store them in my car?
