Toxic (9)

I believe the answer is:

poisonous

'toxic' is the definition.
(synonyms)

This is all the clue.

(Other definitions for poisonous that I've seen before include "Potentially deadly" , "Extremely malicious" , "Noxious; malicious" , "Toxic, venomous" , "not safe to drink" .)

I've seen this clue in the Sydney Morning Herald.
