There are several ways to create realistic smoke effects in After Effects. You can use the built-in particle systems like Particle World or Particle Playground, apply the Turbulent Noise effect to a solid layer, use third-party plugins like Trapcode Particular, or even animate shape layers with gradients to simulate smoke movement.
