chain-smoke

I'm a little stuck... Click here to teach me more about this clue!

'light up repeatedly man chokes terribly having inhaled one' is the definition.
I can't judge whether this defines the answer.

'light up repeatedly man chokes terribly having inhaled one' is the wordplay.
I cannot really see how this works, but
'man' could be 'n' (knight, a man in chess) and 'n' is found in the answer.
'one' could be 'i' (Roman numeral) and 'i' is present in the answer.
'light up' could be 'smoke' (I've seen this in another clue) and 'smoke' is located in the answer.
The remaining letters 'cha' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...

Can you help me to learn more?
