Vapo steam

"Vapo steam" or "VapoSteam" usually does not refer to a specific e-cigarette brand. According to the search results, it most commonly points to the following two completely different products:
Medication: Vicks VapoSteam
This is actually an over-the-counter medicine, mainly used to relieve symptoms such as coughing and nasal congestion caused by a cold.
Product properties: It is a liquid medication that cannot be taken orally. It needs to be used in conjunction with a hot steam evaporator or humidifier.
Working principle: When it is added to the device, the medicine will evaporate along with the steam, achieving the effect of moistening the respiratory tract and relieving coughing. Its main active ingredients include camphor, etc.
Main product lines: There are regular versions, double-strength versions (Double Strength), and various other versions such as Lavender.
User review: It can effectively help relieve nasal congestion and cough, making breathing more smooth. However, some users have reported that if the humidifier is not cleaned properly, the water quality may turn yellow.
Electronic cigarette-related products (secondary possibility)
In the search results, there were also some electronic cigarette products with similar names, but their correlation was relatively low:
DR.VAPE: Vapor Doctor is a Japanese e-cigarette brand. Its "Classic Smoke" cartridge does not contain nicotine or tar. It should be noted that this brand name is not exactly the same as "Vapo Steam".
Vape Master (vapamaster): An electronic cigarette brand claiming to be from North America, it has already opened several stores in the Chinese market. Similarly, its brand name also differs significantly from "Vapo steam".
Summary
In general, the "Vapo steam" you encounter in most cases should refer to the cough suppressant products of the Vicks brand, rather than electronic cigarette products.
