I am currently a heavy 7 oh user and have been for over a year. I'm up to 300 mg + a day. Mainly powder versions. We'll I ran in to people on reddit talking about a new product called mgm15 to get around the 7 oh ban in Florida. I joined the mgm15 Reddit page and ended up finding 3 of the larger vendors and joined their discords. I'd order 2 gs of 7 and 2 gs of mgm15. Well 3 different vendors shipped me mgm15 and when I tested it for fent, they popped positive. I ended up taking and at home drug test for fent and failed and so did my wife. My question is what should I do about it? Should I blast them on Reddit? That's fucking with people's lives.

You should make sure the test couldn't false positive you, like did you even test your 7-oh? But I would say at least warn people on the reddit that it could be the case. Im not sure how these indoles act as far as false positives go, but seeing as they are a completely different class of chemicals I would say its really got me worried, its best to warn folks. Also, I don't want to make you wast your money, but maybe think of sending a sample or a few to

They can help get the info out.

I tested positive for fent after taking 7oh tabs from a smoke shop. Almost lost me my housing and turned my brothers wife absolutely paranoid

4th vendor I ordered from tested positive for fetty. I ordered from a 5th vendor and will see what it shows.

I think it’s likely that 7oh gives false positives for fetanyl.

Perhaps, but why would that be so? Fentanyl tests are supposedly accurate for differentiating fetty from heroin and oxycodone and other opiates. Why would it be any different for MGM 15 when it's a different family of chemicals? If so then fentanyl tests are pretty useless

I don’t know or pretend to understand but false positives are very common with drug tests for certain substances. I believe cocaine is relatively straightforward to test for and false positives are extremely uncommon for cocaine. But for many drugs false positives are very possible

You go around buying weird drugs off the internet & are shocked they are made in some weird Lab or somebody's bath & have weird stuff in it, are you really that stupid? Yes I guess you are.

Mitragynine alkaloids also have a completely different structure than fentanyl. IIRC the ground structure is much closer to ibogaine than fent. Not to say that this excludes the possibility of a false positive but assuming this new compound is a variation of 7OH it doesn't appear to make much sense why this compound would be flagged for fent while 7OH is not.

Drugs (especially supposedly legal ones) sold over some fishy discord server should raise alarm bells, especially if the product you received tests positive for fentanyl. It might be a good idea to write up your findings and try to get a discussion going on reddit but I wouldn't be surprised if the related sub is moderated by vendors and that you would be banned in no time. Posting a warning on bluelight sounds like the more sensible approach.

Did anyone that found these posn,try the product? And did it feel like fetty?

I did about 6 bumps in my nose one day (maybe 100 mg) and was nodding out at work (thank God I work at an office where I manage the place and could shut my door for 6 hours) . That's why I took a urine test which I failed. I knew something was wrong.

Also, I now have ordered a 4th batch that is popping dirty with f and it's a well known vendor. I'm thinking anyone claiming 98% - 99% mgm15 is selling the fent laced product. None of them can give you a coa.

What does this kind of response achieve?

The poster is trying to raise awareness about something which could impact people's health and wellbeing, which seems like harm reduction to me. I wouldn't just call fent "weird stuff". It's a particularly dangerous substance and it's one that plenty of people would like to stay far away from.

Are you suggesting that we all "just say no" because that's the smart thing to do?

MGM can cause false positives for fetty so before you go "blasting" people on Reddit you should do your research. There are so many stories of people popping positive for fentanyl but when it's actually sent to the lab it is negative. Dude ruining people's businesses isn't some game or a joke. Before you even think of making a public online claim like that you need to be 1000% positive of what you are saying

Exactly! MGM is famous for causing false fetty positives and if this guy had done his due diligence he would have known that. Just out here ready to ruin people's businesses and shit and he's not even 100% sure

I also failed 2 urine tests for fent after taking the mgm15. So we're those false positives as well? You're mighty defensive so you must have skin in the game. Everyone I ordered from that their stuff popped for fetty used the same lab/manufacturer. There is no such thing as 98% - 99% our mgm15. Its a made up drug and you will never see a single lab report showing it. I'll be my life that you've never once seen a lab report for mgm15. I k ow because no body runs tests for it. That's from someone who makes 7 and mgm15.
