This might be called for since this forum deals with plants and substances a lot more dangerous and difficult to use than the other forums.
A certain level of discretion is essential. Nobody wants anyone to die just because of bad advice.
Dosages should never even be mentioned because they imply that Xg of one datura is the same as Xg of another. Since potency can vary within the same family and even within the same habitat, one persons dosage with one specific plant is useless information, IMO.
When someone who clearly has no knowledge of nightshades asks for information one should always make the dangers of these plants clear and never directly recommend that they use it. It would be easy to UTSFE them, but if someone asked "I just found a gun, would it be like playstation if I shot someone with it?" you wouldn't do that, you'd make time to answer them properly.
I know I posted dosages for various nightshades in the earlier days of the forum, based on a book I found, but I have edited that post and am currently in the process of editing all my posts in this category.
So what can be discussed? Cultivation, history/mythology, experiences could also be shared, but they should perhaps refrain from gloryfying too much.
It would be great if everyone who had one, gave their opinion on this, I feel it's a discussion we should have taken a long time ago, even if it was covered a little bit in the "ethics of Datura suppliers" thread.
