Correct inhalation of e-cigarettes is crucial for achieving a satisfactory experience. There are mainly two technologies: mouth-to-lung (MTL) and direct-to-lung (DTL). Mouth-to-lung inhalation mimics the feeling of smoking.
First, inhale the steam into your mouth, hold your breath, then inhale it into your lungs and exhale. This method is highly suitable for smaller and tighter inhalations, and is most appropriate for e-liquids with a high nicotine content or devices with tight airflows, such as e-cigarette pens or pod systems.
On the other hand, “direct lung inhalation” or “direct to the lungs” inhalation involves inhaling steam directly into the lungs through a steady breath, similar to deep breathing. This method is usually used in conjunction with sub-ohm devices, which can produce greater smoke and are most suitable for devices with lower nicotine content. Try these two techniques to find out which one suits your style and device, and always start with a gentle and controllable suction to avoid coughing or irritation, especially if you are new to e-cigarettes.
