When poison first strikes

Hi

How can I detect when a poison strikes my character?

I'd like to play a sound when my character gets poisoned (any poison, doesn't matter).

Thanks!|||well you will see it on in the buff/debuff menu.|||In PvP terms, if a rogue has hit you - then just assume you've been poisoned ;)|||Ok I didn't explain myself properly ;)

I was wanting to write a script that plays a sound whenever a poison "debuffs" me.
