If my chanuka candles have a good smell to them, can I still get pleasure from the smell after the lighting or are they issur in all pleasure?
Answer:
It is forbidden to derive all forms of pleasure from Chanukah candles. However, it is permitted to use fragrant candles, provided one does not have intention to derive pleasure from them.
