Not that I know of so far. Unless you count Melorine because it is a natural, plant based substance. But weather I would definitely say no. Other forces of nature, I’m not sure yet, but I would venture to say no.
Because Melorine is a natural substance though, the forest//nature nymphs have a higher natural resistance to it than humans. This is one of the reasons Nevaeh was kidnapped to become a runner, because she’s a quarter nymph. Many of Horowitz’s cartel members are addicted to the Mel, but he also have a decent amount of nymphs in his hand, which he uses for runners and other specific jobs that he’s rather not have a druggie doing. In Nevaeh’s case, he sends her on the more public, high-risk drops in the middle of more well to-do areas of Antico, instead of sending someone who looks wasted.
Nevaeh also takes a natural supplement, Silverleaf, that helps the body resist any sort of addiction. With that plus her natural resistance, I believe she’s either 87% or 89% immune to the Melorine.
