Q. As a forensic crime scene detective, I have used Vicks in my nose to block the smell of noxious odors for many years. No adverse effects have been apparent. However, I am aware that adverse effects may still present a serious concern over the long term.
A. We can well imagine that a forensic crime scene investigator would have to deal with some pretty stinky situations. The strong aroma of Vicks can mask other smells.
We have heard from readers that horse trainers sometimes utilize this unique property of Vicks: “My friend raises and shows palomino horses. When she shows the stallions, she puts a little bit of Vicks inside their nostrils so they won't get a sniff of a mare in heat and act like a typical male and show off. If they can not smell the mare, they behave properly.”
A zoo in England has used Vicks to mask the scent of newcomers in a group of meerkats. Without some such intervention, they are likely to fight.
