It's actually the wick that is most important when discussing candles. Find candles that have a wick with a high zinc content, they produce less smoke. Also, keeping the wick trimmed short will reduce the amount of smoke the candle produces.
Soy candles do not give off the dangerous toxins and soot that other candles give off. They are definitely a healthy alternative.
Generally speaking smoke IS pollution.
No, because candles do not give off Carbon Monoxide.
Home smoke detectors generally respond to smoke, or products of combustion more readily than heat. Unless the candle was placed directly under the detector, it is unlikely to produce enough heat to trip a heat element. It is very possible though, that it could give off enough combustion products to set off the smoke detector.
Yes because they emit or give off light
Empty the joint into a a bowl and smoke it. Joints are on of the least efficient ways to smoke.
In "Lord of the Flies," the boys use green branches and leaves from the island to make the fire give off more smoke. They discover that adding these materials helps the fire create more visible smoke signals.

Rapid oxidation, also known as fire, gives off heat, light, and smoke.
Medieval candles were made with either beeswax or tallow (animal fat), perhaps sometimes a mixture of the two. Wax candles were costly, while tallow candles were very cheap, difficult to handle, smelly and gave off large amounts of smoke and soot. Beeswax is a golden ochre colour, while tallow candles are white. Some Church beeswax candles may have been processed to make them as white as possible, since white was the colour of purity. Paraffin wax was not used for candles until 1854 (the modern era).
The volcano will smoke and give off ash.Lava may flow out of the vent of the volcano.
Yes, at least heat and light.
