In fact, there are two types of inhalation: mouth-to-lung and direct-to-lung.
The mouth-to-lung inhalation process is:
- Take a puff of vapour into your mouth and hold it for a few seconds.
- Open your mouth and inhale the vapour into your lungs, but don’t swallow.
- Let the vapour reach your lungs and exhale slowly.
The steps of direct-to-lung inhalation are:
- Take a deep, steady breath before inhaling.
- Quickly draw the vapour into your lungs.
- Exhale vapour immediately.
