Definitions

  • the present disclosure relates to a device for storage and inhalation of vaporized nicotine and a method for manufacturing the same.
  • Smoking is generally harmful with many chemicals such as tobacco, lead, arsenic, benzene and nicotine. Smoking causes cancer, heart disease, stroke, lung diseases, diabetes, and chronic obstructive pulmonary disease (COPD), which includes emphysema and chronic bronchitis.

  • vaping devices In recent times, manufacturers have been known to introduce e-cigarettes or vaping devices by claiming that such devices bypass many of the health risks associated with tobacco smoking. Moreover, many of these vaping devices do consist of toxins such as acetaldehyde and formaldehyde, which are carcinogens. For such devices, it is necessary to heat the composition till it becomes a vapor/aerosol which can then be inhaled by a user. The heating of such composition releases harmful chemicals which are detriment to human health. Moreover, upon inhaling such substances, a user would also exhale smoke. Secondhand smoke causes stroke, lung cancer, and coronary heart disease in adults. Children who are exposed to secondhand smoke are at increased risk for sudden infant death syndrome, acute respiratory infections, middle ear disease, more severe asthma, respiratory symptoms, and slowed lung growth.
