Smoking is the leading cause of preventable death worldwide. It’s estimated that cigarettes kill more than 1 million people each year, with another 600,000 dying from secondhand smoke exposure. While there are many harmful chemicals in tobacco smoke, one chemical stands out above all: nicotine.

Carbon monoxide

Carbon monoxide is a colorless, odorless gas that can be deadly if inhaled in high enough concentrations. It's produced during the combustion of organic materials, such as tobacco products and wood.

Carbon monoxide poisoning is often caused by household appliances that use gas or electricity to run them (like stoves). The most common symptoms include headaches and fatigue; others may experience outlaw tobacco dips or vomiting as well as shortness of breath. If you suspect your home has high levels of carbon monoxide, call 911 immediately!


Nicotine is a stimulant, and it's also a vasoconstrictor. It causes dilatation of blood vessels in the lungs, which increases oxygen flow to your body.

Nicotine is an agonist of nicotinic receptors found throughout your nervous system: in the eye muscles and around nerve endings that respond to sensory stimuli like pain or sensation. This means that nicotine has effects on both voluntary movement (like going for a jog) and involuntary reflexes (such as sneezing).

Hydrogen cyanide

Hydrogen cyanide is a gas that can be found in tobacco. It's also present in some food, including almonds, apricots, and celery. Hydrogen cyanide has been used as a poison for centuries because it affects the brain and heart when inhaled or ingested.

Inhaling hydrogen cyanide can cause dizziness, confusion, and nausea within minutes of exposure to the smoke; however, it may take hours before symptoms appear. 

Once you've been exposed to this chemical your body will begin to release enzymes that break down excess amounts of toxins like nicotine so they don't build up in your system over time (this process takes time). For example: if someone smokes one cigarette every day for ten years then they'll likely see little or no change from this habit until after their first year has passed because their bodies have already adapted over time by breaking down most of what gets into them each day through metabolism reactions like exhaling exhaled smoke from previous puffs taken from cigarettes smoked days ago.


Benzene is a chemical that is found in tobacco smoke. It’s also a known human carcinogen and has been linked to other health problems, such as birth defects, kidney tumors, and leukemia.

You may have heard about benzene before—it's one of the chemicals used to make gasoline or diesel fuel! So when you inhale car exhaust fumes while driving your car along busy highways or going through traffic jams at rush hour traffic lights (both real-world scenarios), there's a good chance you will be breathing in benzene fumes too.


Polonium-210 (Po-210) is a radioactive element that has been used in medicine and industry. Like other radioactive substances, it emits alpha particles when placed under high pressure; these particles can cause damage to cells and DNA.

Po-210 occurs naturally in the environment and is found in some foods but not in tobacco smoke or other products containing tobacco.


Formaldehyde is a colorless, strong-smelling gas. It's used to make building materials and textiles. It can also be found in food and beverages such as wine, beer, fruit juices and yogurt. In addition to these common uses of formaldehyde around you every day now, it has been used as an embalming agent for animals since the 1940s.

Formaldehyde causes cancer in humans when inhaled over long periods of time or exposed at high levels (for example: breathing in fumes from burning cigarettes). This is why we are so afraid of secondhand smoke!

Polycyclic Aromatic Hydrocarbons (PAHs)

PAHs are a group of chemicals that can be found in outlawdip, coal tar, fossil fuels and creosote. They are also found in foods such as coffee, cocoa and potatoes.

PAHs have been linked to cancer because they cause mutations to DNA over time. When you inhale these carcinogens into your body they damage the cells that line your lungs so that they can't function properly. The damaged cells then become cancerous tumors which multiply rapidly causing more damage to other parts of your body such as skin or liver cells before eventually killing them off completely!


Nitrosamines are a group of chemicals that are formed when nitrites and amines are heated together. They can be found in various foods, tobacco smoke, and alcoholic beverages, including beer. Nitrosamines are also known to be toxic to humans and cause cancer.

Methyl isocyanate (MIC)

Methyl isocyanate (MIC), a chemical compound used in manufacturing and agriculture, has been linked to cancer and other health problems. It's also suspected of causing damage to the environment because it can cause water pollution when released into waterways.

Chemical found in tobacco smoke that is also used in chemical weapons

The chemical is an oily liquid that can be found in tobacco smoke. When inhaled, it causes irritation to your respiratory system. It also causes damage to cells and tissues, which can lead to cancer.

This chemical has been shown to cause harm by causing mutations that lead to cancerous tumors and other health problems. In some cases, this can even be fatal!

It's important for you to know what you're putting into your body so that you can make informed decisions about what products are right for your needs or lifestyle.
