A U.K. man, whose effort to feed his drug habit led to a nationwide recall of a painkiller, has been given 18 months in jail. The 31-year-old, Christopher McGuire, admitted that he put some of the antipsychotic drug Seroquel XL that he was taking into packets of the over-the-counter painkiller Nurofen Plus that he wanted for his drug addiction, reports the BBC. Nurofen Plus contains codeine and ibuprofen, and McGuire was taking about 32 tablets a day. He would switch out the mixed up drugs with fresh packs at pharmacies during the distraction caused when he pretended to buy them. A couple of the mixed packs left on the shelf were picked up by customers, who reported getting drowsy. The scam saved him about $11 but cost drugmaker Reckitt Benckiser about £2.4 million ($3.8 million) when it issued the recall. It also led to an investigation by Scotland Yard. Story | More
