4-ACO-DMT (4-acetoxy-n,n-dimethyltryptamine), or O-Acetylpsilocin, is a psychedelic drug (hallucinogenic) in the tryptamine class of drugs (like LSD and psilocybin). It is the acetylated form of the psychedelic mushroom alkaloid psilocin (4-HO-DMT). It is a more stable compound than psilocin, and has a longer shelf life. It is commonly called "psilacetin" among its users. It is usually found in crystalline/powder form, in either it's fumarate or HCl salt. The dosage varies between 10 and 25mg. 25mg is approximately equal to 4 grams of good psychedelic mushrooms (17mg of psilocin, there is approx. 15mg of psilocin in a good 1/8th ounce of mushrooms). The effects are VERY similar to a mushroom trip, except it lasts a little longer than mushrooms (around 7 hours). Its effects, however, differ somewhat from mushrooms. It seems to have a much more relaxing quality to it, which makes it harder to have a bad trip. Several available reports of 4-ACO-DMT compare it favorably to psilocybin, describing it as more euphoric, gentle, warm, and colorful. It has also been described as less jarring/scary, and less likely to produce nausea. I and everyone I have talked to who has tried it loves it (most more than mushrooms). Users report dose-dependent colorful visual effects and a sense of physical energy or euphoria, sometimes accompanied by abstract, associative, "trippy" thought patterns, or derealization. It is almost always taken orally, but can be taken by other methods. ...more...
