Second-hand vape inhalation: Potential hazards and consequences
Reducing Secondhand Vape Exposure: Protecting Young Adults' Health
Secondhand vapor from e-cigarettes can pose significant health risks, especially for young adults. This is due to the presence of nicotine, heavy metals, carcinogens, ultrafine particles, volatile organic compounds, and other toxic substances released into the air by the exhaled aerosol from e-cigarettes [2][4].
Research has consistently linked vaping, including secondhand exposure, to increased respiratory conditions such as asthma, as well as lung inflammation and injury. Young adults exposed to vaping may develop breathing problems, potentially worsening existing conditions like asthma or chronic obstructive pulmonary disease (COPD) [1][2][4].
Moreover, vaping is associated with mental health concerns such as anxiety and depression, partly due to nicotine’s effects on the developing young adult brain. Secondhand vapor exposure also carries these risks indirectly [1][2].
Long-term consequences of secondhand vape exposure include increased risks of cardiovascular diseases, potential cancer hazards, and mental health problems. Young people may also be more likely to progress to cigarette smoking and use of other substances, increasing risks over time [1][3][5].
To minimise exposure, it is best to avoid vaping around babies, toddlers, pets, and any others at risk of secondhand or thirdhand vape exposure. Avoiding smoking indoors or in cars can also help reduce the risk. Asking any visitors to smoke outside can further reduce exposure [6].
Spending time in a smoke-free environment can significantly reduce the risk of secondhand smoke and vape exposure. Harmful chemicals from vaping may stay in the air long after people stop vaping, so keeping a smoke-free home is essential [7].
Vape chemicals in the air can increase concentrations more than 3.6 meters away from the original vaping source, so keeping rooms well-ventilated can help reduce exposure [8].
When quitting vaping, it is crucial to get rid of all vaping products on the chosen day and to plan positive distractions for any urges to vape. Gradually decreasing the amount of vaping before the quit day can aid in successful quitting [9].
Keeping reminders of the reasons for quitting can help maintain motivation during the quitting process. Talking with a healthcare professional or quitting support service can provide help and advice on quitting successfully [10].
Nicotine exposure in early childhood may increase nicotine dependency later in life, so it is essential to avoid babies and young children being exposed to secondhand vape or vape aerosols. Baby clothes and toys may absorb nicotine, and tobacco-specific nitrosamines (TSNAs) may form [11].
Young children may be especially at risk of thirdhand exposure due to hand-to-mouth behaviors. It is best to avoid using vaping products inside the house to prevent secondhand exposure to harmful vape aerosols [12].
In summary, secondhand vape exposure in young adults can lead to respiratory diseases (like asthma), cardiovascular risks, potential cancer hazards, and mental health problems due to inhalation of toxic substances in the vapor. While some variations exist due to differences in device types and exposure levels, the evidence supports precautionary measures to minimise exposure, especially in young populations [1][2][4][5].
Planning healthy snacks, such as nuts, fruit, vegetables, and sugar-free chewing gum, can support quitting efforts. Healthy distractions can help manage cravings and maintain a smoke-free lifestyle [13].
