Bromo-DragonFLY is a psychedelic hallucinogenic drug related to phenethylamine (a chemical found in chocolate, which like amphetamine, causes the release of norepinephrine and dopamine in the brain). It 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 (up to several days).
It is explicitly illegal only in Finland, Sweden, Norway, and Denmark, although it may be considered a controlled substance analogue under US and Australian drug laws. The compound was first synthesized in the lab of American pharmacologist David E. Nichols in 1998. As with the earlier and less potent dihydrofuran series of compounds nicknamed FLY, Bromo-DragonFLY was named after its superficial structural resemblance to a dragonfly.
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. The toxicity of Bromo-DragonFLY appears to be fairly high for humans when taken in doses above the therapeutic range. In 2009, a 22 year old man from Copenhagen died after ingesting Bromo-dragonfly. His friend described the trip saying, ‘It was like being dragged to hell and back again. Many times. It is the most evil [thing] I’ve ever tried. It lasted an eternity.’
In 2011, in the United States, two young adults died after overdosing on Bromo-DragonFLY, which they thought was 2C-E (a less potent member of phenethylamine family), and several others were hospitalized during the same incident. The deaths occurred after a fatal miscalculation in dosage. Those who took the drug received, in some cases, 100x the normal dose. Both deaths were very violent, resulting in massive seizures, vomiting blood, and terrifying hallucinations, and several surviving victims are still suffering from its effects.
