Certain substances, when combusted and inhaled, emit an aroma characterized by sweetness. This olfactory property can arise from the chemical composition of the substance itself or from the byproducts generated during the combustion process. An example includes illicit substances containing flavor additives or naturally occurring compounds that decompose into sweet-smelling molecules upon heating.
The presence of a sweet smell during smoking can be misleading and potentially dangerous. Individuals may be drawn to the scent, unaware of the potential health risks and addictive properties associated with the substance. Historically, anecdotal evidence and personal accounts have often been the primary source of information regarding this phenomenon, but scientific analysis is required to determine the specific compounds responsible for the perceived sweetness and associated health impacts.
