It is, and I'm very sorry for all those involved and especially she herself of course.
If what happened was an aneurysm, and it was from only 1 blotter... whatever the compound was it seems to me like there are no drugs on blotter available that would pose a huge risk causing this. By that I mean that vasoconstrictive potent stimulants like DOI or other DOX as well as NBOMe's should not typically cause this but a lot of them can if you are very unlucky. Look, when people get hurt they lash out and often blame. Sometimes there is a sound argument that this blame is deserved, in other cases not. If the drug was not misrepresented and turns out to be DOI, my opinion is NOT that it is right to think any blame should be put back to you guys - instead... I'd say don't blame anything at all because sometimes these things happen - people get aneurysms without having taken any drug at all. If your friend was sensitive to get one, who knows if she would have gotten it from sports and exercizing instead of taking the drug.
We don't know that! So please don't blame yourself and don't put any blame where you don't know it belongs. None of this is meant as disrespect.
The cyanosis (blue extremities) and blood issues do suggest there is more going on though, and I am still quite worried about anything that would fit on a single blotter hit and do that.
Are you certain only 1 dose / square was taken... was it thin paper or thick (not sure if you are familiar with typical LSD blotter) ?
I'm sorry not to offer more consolation but if you can find out what was in it, we can put it up...
As unwise as it was to ingest blotters like this without testing them first or doing allergy tests, there is SO MUCH that is unwise about what we all do taking drugs. I generally recommend people getting their product tested but how many people actually do that 100% of the time? I have so many samples of weird shit, how many of them are confirmed? How many times have I taken powders based on trust only? I never took drugs from strangers at parties, that goes too far for me... but I realize that there are many occasions where the same that happened to your friend could have happened to me. Same goes for most people on this forum if they are honest.
Fortunately, most of the time we get away with it... but the times we don't remind us that our "system" is flawed, and we are ALL unwise. Because I think almost every blame is to be put on our flawed system, I think that doesn't make you especially guilty: you are not. I think the flaw in the system with drug-taking is that most people trade some security (i.e. not getting everything tested all the time) because the chance of disaster *seems* small. We tend to blind ourselves in foresight, and overreact in hindsight - like never taking drugs again even if getting them tested makes the system a lot more secure.
Example: if you step into a car with someone else, there is some chance that an accident will happen. It is significantly more dangerous than *not* driving, for sure. When that accident happens even if all participants had the best intentions to keep everyone safe, who do we blame? I think it is realistic to see that participating in traffic was dangerous to begin with and you got a bad deal. For a lot of people, participating in traffic is a necessity while taking drugs is not. I hate the word 'necessity' quite often, this is just a choice. I take it you had the best intentions for everyone to be safe. Your friend chose to participate in the whole 'system' of drug-taking.
Hopefully some of the logic I can offer will help you - none of it is meant to make us consider all of this less horrible.
