Toxicology (from the Greek words τοξικός - toxicos "poisonous" and logos) is a branch of biology, chemistry, and medicine concerned with the study of the adverse effects of chemicals on living organisms. It is the study of symptoms, mechanisms, treatments and detection of poisoning, especially the poisoning of people.

Dioscorides, a Greek physician in the court of the Roman emperor Nero, made the first attempt to classify plants according to their toxic and therapeutic effect.Ibn Wahshiya wrote the Book on Poisons in the 9th or 10th century.

Mathieu Orfila is considered to be the modern father of toxicology, having given the subject its first formal treatment in 1813 in his Traité des poisons, also called Toxicologie générale.

In 1850 Jean Stas gave the evidence that the Belgian Count Hypolyte Visart de Bocarmé killed his brother-in-law by poisoning with nicotine

Theophrastus Phillipus Auroleus Bombastus von Hohenheim (1493–1541) (also referred to as Paracelsus, from his belief that his studies were above or beyond the work of Celsus - a Roman physician from the first century) is also considered "the father" of toxicology. He is credited with the classic toxicology maxim, "Alle Dinge sind Gift und nichts ist ohne Gift; allein die Dosis macht, dass ein Ding kein Gift ist." which translates as, "All things are poison and nothing is without poison; only the dose makes a thing not a poison." This is often condensed to: "The dose makes the poison" or in Latin "Sola dosis facit venenum".

Amy Jade Winehouse (14 September 1983 – 23 July 2011) was an English singer and songwriter known for her powerful deep contralto vocals and her eclectic mix of musical genres including R&B, soul and jazz. Winehouse's 2003 debut album, Frank, was critically successful in the UK and was nominated for the Mercury Prize. Her 2006 follow-up album, Back to Black, led to six Grammy Award nominations and five wins, tying the then record for the most wins by a female artist in a single night, and made Winehouse the first British female to win five Grammys, including three of the "Big Four": Best New Artist, Record of the Year and Song of the Year.

In 2007 she won a Brit Award for Best British Female Artist; she had also been nominated for Best British Album.
