Re: They may wish to reword and correct the notice...
I did a summer job in a Chemists in the 1970s and there was a cough medicine called Collis Brown's Compound. It contained a fair amount of codeine but was sold over the counter without any real restrictions. There were some customers who bought half a dozen bottles a week and were clearly addicted. I was was told later that the manufacturers were forced to reduce or remove the codeine entirely causing a rush to the local GPs for 'nervous' problems.
