POISONS ACT 1972
It has been brought to our attention by the Trading Standards service that nicotine sold in liquid form should not be more than 7.5% weight in weight. As a precaution, we have removed our fluids with nicotine, the 36MG, 24MG, 18MG, 11MG and 8MG ranges, until we have been able to have these tested and they comply with the standards set out.

It looks like UK authorities are starting to clamp down on nicotine liquid, this might be a good time to stock up from the sellers who are still trading.
