Bromo-DragonFLY, also known as ABDF, or "Placid" is a psychedelic hallucinogenic drug related to the phenethylamine family. Bromo-DragonFLY is considered an extremely potent hallucinogen, only slightly less potent than LSD with a normal dose in the region of 200 μg to 800 μg, and it has an extremely long duration of action up to several days. [1] It is explicitly illegal only in Sweden [2] and Denmark, although it may be considered a controlled substance analogue under US and Australian drug laws. Bromo-DragonFLY has a stereocenter and R-(-)-bromo-DragonFLY is the more active stereoisomer.



Bromo-DragonFLY was first synthesized by Matthew Parker in the laboratory of David E. Nichols in 1998. It got its name from an earlier and less active dihydrofurane series of compounds nicknamed FLY due to the molecule's superficial structural resemblance to a fly.


The hallucinogenic effect of bromo-DragonFLY is mediated by its agonist activity at the 5-HT2A serotonin receptor. Bromo-DragonFLY also has a high binding affinity for the 5-HT2B and 5-HT2C serotonin receptors, and is most accurately described as a non-subtype selective 5-HT2 agonist, as it is actually twice as potent an agonist for 5-HT2C receptors as for 5-HT2A, as well as being less than 5x selective for 5-HT2A over 5-HT2B.[3]


The typical dose of Bromo-DragonFLY is not known, however it has varied from 500 μg to 1 mg. [1] It has about 300 times the potency of mescaline, or 1/5th the potency of LSD. It has been sold in the form of blotters, similar to the distribution method of LSD, which has led to confusion, and reports of mistakenly consuming Bromo-DragonFly. It has a much longer duration of action than LSD and can last for up to 2–3 days [1] following a single large dose, with a slow onset of action that can take up to 6 hours before the effects are felt.

The toxicity of Bromo-DragonFLY appears to be fairly high for humans when taken in doses above the therapeutic range, with reports of at least five deaths believed to have resulted from Bromo-DragonFLY reported in Norway [4], Sweden, [5][6] Denmark[7][8] and the United States. Laboratory testing has confirmed that in October 2009, a batch of Bromo-Dragonfly was distributed, mislabeled as the related compound 2C-B-FLY, which is around 20x less potent than BDF by weight. This mistake is believed to have contributed to several lethal overdoses and additional hospitalizations. The batch implicated in these deaths also contained significant synthesis impurities, which may have contributed to the toxicity.[9 ]

Also, a Swedish man had to have the front part of his feet and several fingers on one hand amputated after taking a massive overdose. Apparently the compound acted as a long-acting efficacious vasoconstrictor, leading to necrosis and gangrene which was delayed by several weeks after the overdose occurred. Several other cases have also been reported of severe peripheral vasoconstriction following overdose with Bromo-DragonFLY, and a similar case is also known from DOB. Treatment was of limited efficacy in this case although tolazoline is reportedly an effective treatment where available.[10][11]

Overdoses, disturbing experiences, and Bromo-DragonFLY associated health problems have been described. One case in 2008 in England involved inhalation of vomit, causing nearly fatal asphyxia.[12]

October 3, 2009 a 22 year old man from Denmark died taking Bromo-dragonfly. His friend described the trip as "It was like being dragged through Hell and back again. Several times. The worst trip ever. It lasted forever" [13]

Legal Status


Bromo-DragonFLY was classified as a "health hazard" in Sweden on July 15, 2007, making it illegal to sell or possess there. [14] [15]


On December 5, 2007 the drug was banned in Denmark.[16] The substance has been declared illegal by health minister Jakob Axel Nielsen, following recommendations from the Danish Health Ministry. It is currently classified as a dangerous narcotic and therefore its possession, manufacture, importation, supply or usage is strictly prohibited. Anyone involved in such activities can face legal action. [14]


Bromo-DragonFLY is currently not on the Norwegian narcotics list, [17] but is affected by Norwegian derivate laws according to state officials. [18] Thus it is effectively a narcotic drug by Norwegian law.
