The word “Toxic” as an adjective:

(1) of, pertaining to, affected with, or caused by a toxin or poison: a toxic condition.
(2) acting as or having the effect of a poison; poisonous: a toxic drug.
(3) causing unpleasant feelings; harmful or malicious: a toxic boyfriend who wanted complete control over her; toxic criticism.

I am NOT a lawyer, however, to me, the term, “toxic environment’ seems to be very hard to prove, and Cade has upon him, the burden of proof.

Only time will tell.
