The major issue here with this last method is that you still have to source your own psychedelics through unregulated underground markets, which can lead to all kinds of issues with adulteration and misrepresentation. This isn't really an issue for whole psilocybin-containing mushrooms, but when you get into the realm of pressed pills or bags of off-white powders, things get more risky.

To help people navigate underground markets as safely as possible, we made a resource called Dealing With Your Dealer which you can download for free.

We also recommend testing your drugs using chemical reagents and fentanyl strips.

These methods used together are fairly accessible for most people, but they can't catch all adulterants, so if you have $100-150 to spend in the name of safety, we also recommend using a laboratory service like DrugsData.org , energycontrol-international.org , or GetYourDrugsTested.com (depending on where you live). This is the only way to guarantee you know what you have and can make an informed choice about whether you want to take it.
