I think they re-classified it and it's no longer available over the counter. As far as I'm aware it was not banned entirely. I wouldn't know, I stocked up considerably right after the ban, before it disappeared from online stores (but after it already disappeared from Amazon). I figure they wouldn't ban it if it didn't work, like most supplements.
NAC is amazing! We have it available here OTC. I wanted to get in higher quantities from the US but I might not be able to do that, then.
Check this random factoid out: "After about two weeks of 2,400mg NAC supplementation, cigarette usage appears to be reduced voluntarily by around 25%."
I personally take it for my liver. It does wonders to it, similarly to silybilin.
Also note the absence of that sweet/sickly smell on one's breath. This implies a reduced level of circulating acetaldehyde, the primary carcinogen associated with alcohol consumption.
