2. Make it any size you want,
3. Where it says "Background Contents" set that to white,
4. Click Okay,
5. Use the Paint Bucket tool to make the background layer black
6. Create a new transparent layer
Step 2: Base of Your Smoke
1. Pick a grey colour (Make sure you have the transparent layer selected),
2. Draw a squiggle in a medium to large brush,

Step 4: BONUS SECTION! Colouring Smoke
Well here i would like to tell you all my little fun part for this effect coloring, in this example and these picture ill be making it bright green but it can be absolutely any color you want. (bright green doesn't look too good i prefer blue but this is for display purposes only so it shouldn't matter)
1. Make a new layer above your smoke,
2. Make your brush size huge so it covers almost all of your document,
3. Select your chosen colour,
4. Completely cover the document in the colour,
5. Change the belending mode to Overlay an Voila! Coloured smoke
