Discussion Overview

The discussion revolves around the effectiveness of candles in reducing cigarette smoke odor, exploring various explanations from physics, chemistry, and psychology. Participants examine the mechanisms by which candles may mitigate the smell of smoke, including sensory perception and chemical reactions.

Discussion Character

  • Exploratory
  • Technical explanation
  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • Some participants suggest that lighting a candle can help mask the smell of cigarette smoke by overworking odor receptors in the nose.
  • Others propose that even plain candles may have psychological effects that alter the perception of the room's atmosphere.
  • A participant mentions that certain candles are formulated with enzymes designed to neutralize smoke odors.
  • Another viewpoint highlights that the high temperature of a candle flame may oxidize odor-causing compounds in cigarette smoke, converting them into less offensive substances.
  • Some participants express skepticism about the effectiveness of candles, questioning the oxidation rate compared to the volume of air in a room.
  • There is a mention that the most effective way to eliminate tobacco odors is to avoid smoking indoors altogether.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the mechanisms by which candles reduce smoke odor, with multiple competing explanations and some skepticism about their effectiveness remaining evident throughout the discussion.

Contextual Notes

Limitations include the lack of empirical evidence supporting the various claims made about the effectiveness of candles and the dependence on specific types of candles for odor reduction.

Hi everybody,

I know some of my friends use candles when they smoke in a room saying that it can get rid of the cigarette odor. Can you explain it by physics (or chemistry).
I really do not know if this topic is suitable in here.
Thanks

It's not physics or chemistry- it's anatomy. Your nose has a certain number of odor receptors that can be "overworked". If you light a candle with a pleasant smell, it can prevent your nose from detecting the smoke smell.

Oh, it sounds cool. Thank you.
But I am still confused. Sometimes they even use plain candles which have almost no smell (except whey you blow it off). Or it is because of the psychology reason in this case?

It also 'diffuses' the smoke in the room ---disrupts the 'layering' effect which annoys* some people ---

psychology reason?---changes the mood/atmosphere of the room, even without someone smoking---to quote the ex-girlfriend, again, -> romantic

yeah i was also told by my friend to light a candle in a smoking room to avoid smoke odor. What is the reason behind this? Really confusing.

You mean all sorts of candles ? !

Common use candles, birthday candles !

No, just those which have a special enzyme plug embedded in the candle close to the wick.
I have one here now.
BTW, they are expensive.

Some of those special candles have the enzymes throughout the candle(no plug)
 
Candles help to reduce tobacco odor in yet another way. Specifically, the high temperature of the flame promotes the oxidation of odor causing compounds (such as cigarette tar) to odorless carbon dioxide and water. In other words, by acting as a 'thermal reactor', a candle flame basically 'burns away' the smelly compounds in cigarette smoke (as well as other foul smelling compounds in the air). For this reason, candles are probably most effective when actually burned while smoking. This way, some of the smoke itself can actually be eliminated before the tar gets a chance to stick to walls, ceilings, and furniture.

On the other hand, NOTHING eliminates tobacco odors like NOT smoking indoors!

There are a number of different sections of olfactory sensors in your nose, similar to the taste buds on your tongue. These sensors pick up different types of odors like sweet, dry, tart, spicy, etc. The particles from the cigarette smoke interact with a variety of these sensors causing your brain to recognize the scent. The fragrance from candles counter balance the negative smell of the cigarette smoke, neutralizing it. Then adds positive, pleasant aromas which causes your brain to tell you that you are smelling something which is good.

Intuitively that explanation seems unlikely to me. What is the oxidation rate of a candle compared to the volume of air in a room?
