Even when the smell does not linger long, hotel staff knows when you vape. Hotel does know when you vaped in the hotel room through sensor. The sensor can detect whether a hotel room has a trace of nicotine or marijuana. It will alert the hotel management once such substances are present.
How can hotels tell if you smoke in the room?
As to the more sophisticated way of detecting cigarette smoke in hotel rooms, this sensor called a FreshAir Sensor does not just detect nicotine and cigarettes, and marijuana but alerts the management about a smoking incident in a hotel room. This is how hotels know you smoked in the room.
Will TSA take out my vape?
Battery-powered E-cigarettes, vaporizers, vape pens, atomizers, and electronic nicotine delivery systems may only be carried in the aircraft cabin (in carry-on baggage or on your person). Remove all electronic cigarette and vaping devices from carry-on bags if checked at the gate or planeside.
Does vaping stain your walls?
The short answer is, yes. Over time, vaping inside of the home will lead to yellow residue stains on walls and furniture. The atomizer inside the vape heats the liquid and transforms it into a vapor. This is a different process than smoking, as the vapor dissipates more rapidly than smoke.
