Your description sounds more like 25c-nbome to me, although it could have been any of the 25x-nbomes. I wouldnt worry about the flashbacks too much as long as they dont bother you. Any intense experience (drug induced or not) will stick in your head. If you are still actually having hallucinations it could be HPPD (Hallucinogen persisting perception disorder), the only thing that has helped me with that in the past (fell asleep on 3.5g of mushrooms) is stopping ALL drugs until it goes away.
As for the guy who gave it to you, he obviously knew exactly what he was selling you. Nbomes are not active orally. Absorbing the chemical through the skin in your mouth or snorting it are the only ways to ingest it that I know of.
Bromo-DragonFLY is a chemical from the same class as the nbomes that has caused some nasty overdoses. (taken from the wiki page on BDF)
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, Sweden, Denmark, Finland 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.
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[citation needed]. Treatment was of limited efficacy in this case although tolazoline is reportedly an effective treatment where available.
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. Seizures have also been reported.
On October 3, 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”
On May 7, 2011, in the United States, two young adults died after overdosing on Bromo-DragonFLY, which they thought was 2C-E, 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 physical effects, not hallucinations.
All chemicals should be respected, especially ones with active doses in the microgram range. Always read as much as you possibly can on any chemical you are about to take (wiki, bluelight, erowid and google are your friends) and ALWAYS question your sources (IRL or not)
Stay safe 🙂
