In the context of biology, poisons are substances that can cause damage, illness, or death to organisms, usually by chemical reaction or other activity on the molecular scale, when a sufficient quantity is absorbed by an organism. Legally and in hazardous chemical labelling, poisons are especially toxic substances; less toxic substances are labelled "harmful", "irritant", or not labelled at all.

In medicine (particularly veterinary) and in zoology, a poison is often distinguished from a toxin and a venom. Toxins are poisons produced via some biological function in nature, and venoms are usually defined as biologic toxins that are injected by a bite or sting to cause their effect, while other poisons are generally defined as substances which are absorbed through epithelial linings such as the skin or gut.

"Poison" is the 1990 single by the New Edition spinoff group Bell Biv DeVoe. This song - in the style of New Jack Swing, a late-80s hybrid of R&B and hip hop - was the group's most successful, and sings of the dangers of falling in love.

While the song samples from hip hop (Kool G. Rap's "Poison"), the line "you can't trust a big butt and a smile" would quickly became a staple of hip hop. In the outro, BBD gives shout-outs to their former New Edition bandmates, Bobby Brown, Ralph Tresvant and Johnny Gill.

On the Billboard Hot 100 singles chart, "Poison" rose from #52 to #38 in the week of April 14, 1990, and eventually peaked at #3 for four consecutive weeks, beginning on June 9, 1990. "Poison" became one of the most successful singles of 1990, and was a staple on MTV and mainstream radio in the summer, spending ten weeks in the Top 10. The song finally fell out of the Top 50 the week of August 25, 1990.

It has been used in film (Pootie Tang), television (It's Always Sunny in Philadelphia, Scrubs), and videogames (2004's Grand Theft Auto: San Andreas, on New Jack Swing radio station CSR 103.9). It is also referenced in the Madvillain song "Fancy Clown."

"Poison" is a pop song by Australian female group Bardot, and was the first single from their debut album Bardot (2000). It was co-written and produced by Australian producer Michael Szumowski.

The single attracted much hype due to its inclusion on the high-rating Popstars program and debuted at number 1 on the ARIA Singles Chart, where it spent two consecutive weeks, and was certified double platinum. It became the sixth highest selling single in Australia of 2000 and was the highest selling single by an Australian act that year. The single was nominated "Highest Selling Single" at the 2000 ARIA Music Awards, but lost to Madison Avenue's "Don't Call Me Baby". "Poison" was also a big success in New Zealand where the single spent 3 consecutive weeks at number 1 and was certified platinum. In Singapore, it reached number 2. It was released in the UK on April 2, 2001, debuting and peaking at number 45.

"Poison" was the tenth single released by the British electronic act The Prodigy on March 6 1995. It was the fourth single from the album Music For the Jilted Generation. For the first time, the contents on the 12" vinyl record and CD single releases were identical.

Maxim Reality provides the vocals for this track with the lyrics:

"I got the Poison/I got the remedy"

"I got the pulsating rhythmical remedy"

The song has a strong similarity to the introduction of Dr. John's "Right Place Wrong Time" and is likely to be sampled from said song.

The music video was directed by Walter Stern. The band perform the track in a basement-like location. By the end of the video, the floor has turned into a mud-bath where Keith Flint is wrestling with other band members.

"Poison" is a song by artist Alice Cooper, released worldwide as a single in 1989 and is featured on his 18th studio album Trash.

This song is one of Alice Cooper's most well-known songs, and provided his last major mainstream hit, in 1989. It has been covered many times by recent pop bands, such as Groove Coverage on 7 Years and 50 Days. The most recent cover is by Tarja Turunen (ex-lead singer of Nightwish) on her 2nd studio album My Winter Storm.

The lyrics describe the narrator's love for a femme fatale, but it has been speculated that the woman may not be "the poison running inside my [Cooper's] veins." The song changes key 4 times in the chorus, quite unusual in a straight rock song.
