Cardamine

[McNeo]

Calmer state of mind? I'd argue that the cardamine infocard says exactly the opposite.

I believe that "intense" and "euphoria" are pretty close to each other.

As for addiction? I think it's a little bit like Cocaine, with small amounts, very diluted, there is enough of a high to enjoy it recreationally, but 98% of the time, that leads to permanent addiction, and a serious problem.

Nowhere does vanilla say how long it took for the hispanians who landed on Malta to discover that they needed it to survive. Just, when they started exploring, they experienced wierd side-effects which got more intense the longer that they stayed away.

I'd actually argue that it's far more likely to take at least a few years of use, ie long term use, to become physically addicted (obviously the psychological aspect is much quicker).
