Andrew Robert Gallimore (b. 1980 or 1981; age ~years), also known by his handle Alien Insect, is a British neurobiologist, chemist, and pharmacologist who studies psychedelic drugs, particularly dimethyltryptamine (DMT). He is also a historical scholar of DMT. Gallimore resides in Japan and works at the Okinawa Institute of Science and Technology.
Gallimore and Rick Strassman, author of the 2001 book DMT: The Spirit Molecule, have developed a method of continuous intravenous infusion of DMT that they call "extended-state DMT" or "DMTx". It can extend the duration of a DMT experience from a few minutes to several hours. They intend to use it to study the phenomenology of DMT. Other researchers, such as David Nutt, Robin Carhart-Harris, and Matthias Liechti, are also studying DMT by continuous intravenous infusion.
Gallimore believes that DMT experiences are not simply hallucinations. Instead, he suggests that DMT allows the human brain to interface and interact with a deeper level of reality beyond the physical world. Relatedly, Gallimore believes that entity encounters experienced with DMT are real and genuine interactions with beings that he refers to as discarnate intelligent agents.
