Well, be safe. There's a lot of things on the list of "everything" that are a lot less safe than classic psychedelics or even some of the non-classic ones. Do your research well and if you can make sure what ever you have is what you think it is by using testing kits.
Right... I'd stay away from IVing the stuff I extracted with kitchen chemistry, to be honest. Purity might be good, but I wouldn't trust it to go into my veins directly. Not unless I really knew what I was doing and made sure everything was super clean and sterile. Also in general I also don't see much of a point to doing this, especially considering that it's just so much riskier.
This decision is based on experience. We allowed it for a while and it brought with it a great influx of attitudes that were opposite or harmful to the general vision that we have here at the nexus. We are not a forum that encourages safe use of just anything. We specifically focus on the benefits and the science of classic entheogens. We focus on responsability and safety in order to use these tools for mind expansion. While I don't want to judge the usefulness of other substances, I think with many the use comes with such a high risk concerning addiction, long-term physiological damage or similar, or it is simply unknown what risks are involved, so that it is very very difficult to be responsible in using them. This unfortunately seemed to be reflected in the way the discussions went, while it was still allowed, IIRC.
Some substances might be more marginal in terms of risks and safety, however experience has shown that limiting our discussions to the approved substances is positive for the forum, which, in this case, is the most important fact.
