Before you start smoking, it's very important you give the smoke an exit to escape. Without an open window or duct, the smoke will linger in the room and your health will be at risk. Depending on the room you're going to smoke in, there should almost always be some window to open.  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. Next, you'll want to make sure the smoke doesn't get a chance to escape to other parts of the house or building you're smoking in. The best way to do this is by placing a towel (preferably wet) along the bottom of the door. This way, the towel will block off the most obvious place for the smoke to get out. 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. The most important way to prepare before smoking indoors is making sure your room has excellent air circulation. Turning on a fan will disperse the smoke shortly after it forms. The particulars will vary depending on the type of room you're smoking in, but a tabletop fan will work well enough, provided you have it pointed at an open window or duct. 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. Although you'll ultimately want to eliminate the smoke smell for good, another great way of dealing with it when other people are in the house is through masking the scent with another, more powerful one. There are a lot of potential options in this regard; the trick lies in figuring out which one best suits your situation.  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.  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.
