Exit is a not-for-profit, pro-euthanasia organisation based in Scotland that lobbies for and provides information about voluntary euthanasia and assisted suicide.

It has particularly focused on research and publication of works which provide information about suicide methods, including How to Die With Dignity, the first book published on the subject.

[13] Initial legal uncertainties and concerns about adverse publicity however persuaded Exit to release it in Scotland only under the title of a new 'Supplement' to How to Die With Dignity.

Docker & Smith's technical data in support of Departing Drugs was published in a separate volume called Beyond Final Exit, with another contributing author, Bruce Dunn, whose chapter on inert gases laid the foundations for the 'helium method' of suicide.

[14] In 2007, a major revision was needed and Exit published Five Last Acts, a larger book (187 pages) that detailed the use of helium and four other main methods of rational suicide, most of which were not covered in Departing Drugs.

[21] Exit highlights both the benefits and shortcomings of advanced health care directives[22] and has sought to establish proper understanding by means of contributing chapters in both the academic[23] and legal[24] press.

It publishes a substantial magazine, Exit Newsletter, with updates on self-deliverance and living wills, and a mixture of academic and light-reading articles on these subjects.
