How long does it take smell to reach your brain?

    The speed depends on a few factors. 1) the amount of the smell (concentration). Stronger smells are identified quicker and 2) the diffusion rate of the chemicals in the smell. 

    The time it takes for the nerve impulses to travel to the brain is milliseconds. In essence it’s instantaneous. So the speeds depends on the previous 2 factors mostly.
