The phrase "Better Living Through Chemistry" is a variant of a DuPont advertising slogan, "Better Things for Better Living...Through Chemistry." DuPont adopted it in 1935 and it was their slogan until 1982 when the "Through Chemistry" part was dropped. Since 1999, their slogan has been "The miracles of science".[1]
The phrase "Better Living Through Chemistry" was used on products that were not affiliated with DuPont to circumvent trademark infringement. This transmutation is now more commonly used than the original. This statement is used for commentary on several different topics, from the promotion of prescription or recreational drugs, to the praise of chemicals and plastics, to the sarcastic criticism of the same.
