remove THC from the addict trait

[Lady Birb]

The idea of someone addicted to sarin becoming so tolerant to it that it's like soda pop to them would be funny and lead to some Princess Bride gambits

Isn't there a thing where once enough people sign the same Faustian contract it gets replaced with a random weaker but infinite-use effect? That would be a good effect for one of those. You become addicted too, but at the same time immune to, a random powerful poison.
