Air monitors can be used with HPC to forecast potential increases or decreases in pollution and the possible reasons and consequences.

Potential for cities to use white smells to mask bad odours and create less smelly urban areas.

New sensors that similiarly to smoke detectors become ubiqituous in the home sensing particulates.

Vaping alcohol and making it inhalable is a way to ingest drinks through breathing it rather than drinking it in liquid form. Bars may be built around their inhalable experiences.

Different odours have the potential to impact productivity for individuals, what if buildings and the AC was built with scent in mind to enhance the efficiency of workers. Perhaps, this can be done by including nootropics in the air we breathe.

Cities globally install fresh air kiosks that allow people to get fresh clean air whenever they need it.

Smell maps can provide with an understanding of the olfatory landscape of cities, recording how odors change as cities evolve. It can also allow those more sensitive to understand where they should travel in the city.

Terrorist threats could be able to be identified through the use of odour, by using trained neural networks this could be the potential future airport security barrier.

Buildings as part of their branding could have their own scent playlists on different floors to give a varied experience for indviduals.

Fragrance-Free Movements might lead to further individual responsibility of fragrances, and perhaps, this could mean a future where individuals are taxed on their use of chemicals.
