4-Acetoxy-DET (4-Acetoxy-N,N-diethyltryptamine), also known as ethacetin, ethylacybin or 4-AcO-DET is a psychedelic tryptamine. It was first synthesized in 1958 by Albert Hofmann in the Sandoz lab.

It is expected that the compound is quickly hydrolyzed into the free phenolic 4-HO-DET by serum esterases, but human studies concerning the metabolic fate of this drug are lacking.

4-Acetoxy-DET is orally active, and dosages of 10–25 mg are common. Effects last 4–6 hours. The free base is also active when smoked in a dose range of 5–20 mg. Smoking 4-acetoxy-DET greatly speeds up the onset; peak effects are experienced within 10 minutes, and are usually over within 1 hour.

Sveriges riksdags health ministry classified 4-AcO-DET as "health hazard" under the act (translated Act on the Prohibition of Certain Goods Dangerous to Health) as of Nov 1, 2005, in their regulation SFS 2005:733 listed as 4-acetoxi-N, N-dietyltryptamin (4-AcO-DET), making it illegal to sell or possess.
