GW Pharmaceuticals Limited[1] is a British pharmaceutics company known for its multiple sclerosis treatment product nabiximols (brand name, Sativex) which was the first natural cannabis plant derivative to gain market approval in any country.[3] Another cannabis-based product, Epidiolex, was approved for treatment of epilepsy by the US Food and Drug Administration in 2018.[4] It is a subsidiary of Jazz Pharmaceuticals.

History

GW Pharmaceuticals was founded in 1998 by doctors Geoffrey Guy and Brian Whittle. That year, they obtained a cultivation license from the United Kingdom Home Office and the MHRA, allowing the company to cultivate, possess and supply cannabis to conduct scientific research concerning medical cannabis.[5]

Later in 1998, GW Pharmaceuticals entered into a contract with Hortapharm B.V., a cannabis research and development corporation based in Amsterdam.[6][7]

In 2001, GW Pharmaceuticals listed on the Alternative Investment Market, the junior market of the London Stock Exchange.[8] In May 2013, the company became dual-listed on the NASDAQ and AIM.[9]

In 2014, the company made a deal with New York to develop clinical trials using cannabidiol (CBD) to treat children who suffer from seizures and other medical complications.[10]

In May 2021, Jazz Pharmaceuticals acquired the company.[11][12]
