I am building a character that puts the injury drug opium on in multiple Syringe Spears.
Assume that Drugs are not treated as Poisons in any respect given specific reference to the Iron Liver trait.
Personally I see this to be the main reason that Cayden Calen can still enjoy alcohol.
All abilities referenced as working only with poisons do not also work with drugs. This includes Poison Use.
This is part of 12th level campaign and I have already cleared all content posted with my GM.
The Alchemist or Investigator classes can create a whole slew of nasty liquids to inject into people, so I'd suggest checking their "spell list". And since Drugs are alchemical items, you won't be dependent on a supplier.
