No non - scented candles burn faster than scented ones but it really depends on what type of candle they are, who they are made by and ow big they are. E.g non - scented tea light candles burn faster than scented tea lights.
Yes the non-scented canled does burn quicker than the scented candle because of the wax it is made of or because the type of scent it has but if you want a real I have dr.ned biggy here and he said this is true lol lol
