According to research, there are over 40 different chemicals found in various vape juices. Some of these chemicals are harmful and can even be inhaled through secondhand smoke. Below are 5 dangerous chemicals found in vape that can increase mortality rate.


A vast majority of vape flavourants are acetaldehyde-based. When mixed with other commonly found chemicals in vape juice such as Propylene glycol (PG), it leads to the formation of acetals, which are known to aggravate irritation receptors along the respiratory tract. Aside from irritation, it can also lead to inflammation of the airway. Upon contact, it can also cause irritation to the skin and eyes. The effects of long-term exposure to acetaldehyde resembles symptoms of alcoholism. It is also a known carcinogen, with the ability to cause damage to human DNA. Acetaldehydes is used as one of the main components in paint strippers. At an active worksite, the maximum concentration allowed is only 50 ppm. 

N-Nitrosonornicotine (NNN)

Like other nitrosamine compounds, NNN is a known carcinogenic chemical, which means it is capable of inducing cancer. NNN has also been proven to be able to induce oesophageal and nasal cancer. The limit of nitrosamines in consumable products such as cured meats is set at levels below 10 parts per billion (ppb).


Lead exposure may cause anaemia, hypertension, renal impairment and toxicity to the reproductive organs. At high levels of exposure, lead attacks the brain and central nervous system, leading to coma, convulsions and even death. In children, it can cause neurological and behavioural disruption which may result in irreversible mental retardation. The World Health Organisation (WHO) has identified lead as 1 of 10 chemicals of major public health concern. Exposure may come from inhalation of lead particles generated by burning materials and ingestion of lead-contaminated dust.


Low-level inhalation of toluene may cause confusion, weakness, memory loss, nausea, and hearing loss. Inhalation of high levels can cause light-headedness, sleepiness, unconsciousness, and even death. It is also a known irritant to the human eyes, skin and respiratory tract. The vapour form of toluene mixes well with air to form highly combustible mixtures of air. Toluene can be found in aviation gasoline, paint and paint thinners. A highly regulated amount of exposure is allowed at an active worksite to protect workers from harmful effects. 


Benzene is a carcinogenic compound notorious for causing various blood cancers and anomalies in bone marrow function. It is also associated with an increased risk of cardiovascular diseases. Aside from tobacco smoke, major sources of benzene are motor vehicle exhaust and industrial emissions. In the manufacturing industry, The National Institute for Occupational Safety and Health (NIOSH) recommends workers to wear special breathing apparatus when they are likely to be exposed to benzene at levels exceeding the recommended (8-hour) exposure limit of 0.1 ppm.

These are just some of the many chemicals in vape product that may result in detrimental health effects. In reality, the liberty to mix various flavours will cause the formation of hazardous chemical compounds. Seeing as manufacturers may not be aware of these formations, they do not label it on their products. If you are planning to quit vaping or smoking, speak to your doctor about a cessation program that fits you best. Alternatively, visit http://jomquit.moh.gov.my/
