Even with a properly diluted and homogenous product, people will o.d from it. From sheer mishaps. And if your product is diluted exactly to specs, a lot of users will o.d since they assume its weaker. Fentanyl is a moral problem however you try to justify it. You will not save lives through pushing poison on the streets. It's ok if you see it as the end users responsibility or just don't care, or better still: make it for your own consumption. But don't make lame justifications. BS is not cool.
