A fireplace duct is an even better choice, as fireplaces are specifically designed to let smoke escape. It’s not recommended that you try to smoke if the room you’re planning on doesn’t have some kind of access to the outside.
Making the towel wet does add extra protection against smoke, but it might not be a great idea if you’re worried about being caught after the fact. Someone else might notice the wet patch on your doorstep and start asking questions.
Some bathrooms come equipped with special ventilators that clean the air by sucking up excess moisture and particles. If your bathroom has this or something similar to it, turning it on and aiming the smoke towards it could be a quick way to eliminate the smell and visible smoke both at once.
The most common method of masking scent is through using an air freshener. These ‘room perfumes’ will spread a mild, unintrusive smell designed to mute other odors in the air. Air fresheners are very affordable and easy to find. If you don’t already own one, go to your nearest store and purchase one. Once you have it, make sure to spray all around the room, making sure to give attention to the ceiling, corners, and other places the smoke might linger. [3] X Research source If you’re in a bathroom, one effective trick is to put a bit of shampoo in the sink and mix it with some hot water. The shampoo’s aromatic qualities will quickly fill the room, making the subsequent smoke that much harder to detect. Incense is another good choice, and one of the most effective when it comes to masking unwanted smoke. However, keep in mind that incense might raise eyebrows in certain environments, and some people might find the smell just as intrusive as that of a cigarette.
If anyone living with you smokes, and you don’t want them to find out that you smoke: try smoking after them, because the smell from you won’t be as noticeable.
If you have a portable fan, try putting the fan next to the window, aiming outwards. When it comes time to exhale, exhale into the fan from behind it. The fan’s blades will subsequently hurl the smoke outside. If you’re by a window and are looking to not get caught, you should keep an eye on your surroundings outside. If someone’s outside, it might look suspicious that you’re leaning out your window. Exercise alertness and caution.
While you’re at it, you might want to take off any extra layers of clothing you might have. Anything you’re wearing is going to pick up some of the smell, so it’s a good idea to minimize what you’re wearing before you smoke.
Make sure to have somewhere you can quickly discard your cigarette in case someone enters the room. If you’re fast and fluid enough, you might be able to get rid of it without them knowing you were smoking to begin with.
If you were smoking out a window, it’s likely you were dropping the ash out the window. This is a good idea in most cases, so long as you make sure not to let the ash hit the side of the building. If you do, the black trail from your window leading will be a telling sign you’ve been smoking, and the evidence is very difficult to clean up discreetly.
If you’re really cautious and are worried you’ll be caught whilst disposing, you might prefer to seal the cigarette remains in a Ziploc bag. That way, the next time you go out, you can throw it out in a public trashcan.
If your breath is still bad, eating a spearmint candy or gum will fix any lingering smell issues.
It’s recommended you tend to your own laundry yourself if you don’t already. Someone else who is cleaning your clothes might still pick up the smell, even days after the fact.
