In the US, the FDA tried to limit how strong the individual capsules can be (325mg), but you can still buy it in 500mg strength. There are mandatory warnings on the label, but you can buy it in 500-tablet (at 325 or 500) bottles over the counter. It took almost 60 years before the FDA did anything, so a lot of people grew up thinking it was harmless.
