"That Smell" is a song by the Southern rock band Lynyrd Skynyrd, written by two band members, vocalist Ronnie Van Zant and guitarist Allen Collins. JoJo Billingsley also allegedly took part in the writing; however, she was never credited. It was said Ronnie claimed he wanted to fix it. Gene Odom, roadie and childhood friend of Ronnie Van Zant confirmed JoJo as a co-writer. The song was released in 1977 on the album Street Survivors. At the time the song was written, the band had been using alcohol, marijuana, cocaine, heroin, amphetamines, and Quaaludes. Van Zant said that he started using heroin and cocaine to relieve the pressure of performing in front of large audiences.
