Generally banned by 'elf 'n safety as too many kids were getting their front teeth knocked out as a result of a good shove by the school bully when having mouth in close proximity to a hard metal object.
There are probably lots of unfounded hygiene issues etc that may have contributed to this.
I do find it quite ironic that whilst many schools etc were busy removing them, other parts of government were discovering that poor academic performance might be linked to dehydration of pupils coupled with high CO2 levels
Hence the rise and rise of people constantly sucking water from plastic bottles that appear to require surgery to remove them from the hand (and then of course chuck them in the trash bin)
