Yes, you can. The difference is, automotive grade nitrous has hydrogen sulfide so it can`t be inhaled or huffed for recreational purposes (read: getting smashed) Other than that, they are pretty much the same.

Yes, you can use it, no different than the performance grade nitrous other than the mentioned anti-huffing additive.

Legally you can get in trouble having medical grade in your possession if you don't have the proper medical permits, but this is only if the law wants to target you on this fact. Don't get caught providing it to anyone who might misuse it as a recreational drug

I used to own a (N.O.S. brand) cryogenic nitrous pumping station. Nitrous +, or racing nitrous, has 200 ppm of sulphur dioxide in it to prevent abusing it by human consumption. It causes nausea and if enough is consumed, even vomiting, but is not enough to effect performance in any measurable way. But let me tell ya a little secret about "medical grade" nitrous. It often has water in it. Hospitals and doctor's offices filter the gas pretty well and the way it's pulled from the bottle doesn't remove the moisture, so it stays in the bottle, and they don't empty it when they fill them. So when you turn the bottle upside down to get a liquid nitrous transfer, the first thing that passes through is any water that happens to be in the bottle. That happened to me twice using medical grade, which was only because twice, my gas supplier didn't have NOS+ on the truck, only medical grade. I didn't know it happened the first time, because the customer I sold it to didn't use his system for a while, but the 2nd time, I found out almost immediately, then found out about the first time later. I would stay away from medical grade if I were you, or at least take steps to make sure you drain the moisture from the bottle before doing a transfer.
