Creating smoke

The vapour from an e-cigarette is mostly water and much less harmful than a real cigarette, or even an incense stick (especially if you use nicotine-free E-liquid). However they do have low levels of toxicants, so if you don’t want to vape to create the smoke then there are other options. A clothes steamer will work, as will fog machines. Ideally, use a method that lets you target specific parts of the scene rather than cover the entire table in billowing smoke. If you want to use a vape but would rather not blow the vapour with your mouth, you could try using a squeezy bottle or air blower to suck up the vapour then squeeze it out.
