Vaping and heat-not-burn tobacco products like IQOS have risen in popularity as alternatives to traditional cigarette smoking. Both avoid combustion and aim to reduce exposure to some of the harmful chemicals found in cigarette smoke. However, there are key differences between vaping and IQOS in areas like device design, customization, experience, long-term health impacts, and costs that users should understand.

This in-depth guide will compare and contrast vaping and IQOS to help you determine which alternative may better suit your needs and preferences if you’re looking to switch from traditional cigarettes.

What is IQOS?

IQOS, which stands for “I Quit Ordinary Smoking,” is a heat-not-burn tobacco product introduced in 2014 and marketed by Philip Morris International. It works by heating specially designed tobacco sticks at temperatures up to 350°C to generate a nicotine-containing tobacco vapor without burning the tobacco. The tobacco sticks resemble small cigarettes and come in several flavors.

The IQOS system consists of three main components:

• IQOS holder – This is the main device that houses the heating blade and controls. It has a rechargeable battery and allows the user to turn the heater on and off.
• IQOS tobacco sticks – These small tobacco sticks are specifically made for the IQOS system. They contain tobacco powder combined with additional ingredients to make the vapor. The tobacco is heated but not burned.
• IQOS charger – A small charger is included to recharge the IQOS holder after each use, similar to how you would recharge a cell phone.

To use IQOS, a tobacco stick is inserted into the holder. Pressing a button turns on the heater to start producing vapor. The tobacco stick has a filter to allow you to inhale the tobacco vapor like a traditional cigarette, except without burning the tobacco.

Unlike electronic cigarettes that vaporize nicotine liquid, IQOS heats real tobacco. The vapor contains nicotine and tobacco flavors but aims to reduce levels of tar and harmful combustion compounds found in cigarette smoke through heating instead of burning.

What is Vaping?

Vaping refers to the use of electronic cigarettes (e-cigs) and vaporizers to inhale an aerosol produced by heating a liquid, known as e-liquid or vape juice. Most e-liquids contain:

• Nicotine – Like IQOS, vaping aims to offer an alternative way to get nicotine. The level can be customized, including nicotine-free versions.
• Flavorings – From tobacco and menthol flavors to fruit and dessert flavors, vape juice comes in thousands of varieties.
• Propylene glycol and vegetable glycerin – These produce the vapor cloud and throat sensation when vaped.
• Other additives – Small amounts of additives like sweeteners and preservatives may be included.

Unlike IQOS, vaping devices do not contain tobacco. The e-liquid is heated and vaporized at around 200°C through a metal coil inside the vape device. Vaping avoids burning and combustion entirely.

Vaping devices come in many shapes and sizes, but commonly have:

• Battery – Provides power to heat and vaporize the e-liquid.
• E-liquid cartridge – Holds the nicotine e-liquid. May be refillable or replaceable.
• Atomizer – Contains metal heating coil and wicking material to vaporize the liquid.
• Mouthpiece – Allows you to inhale the vapor. Some devices are designed to mimic traditional cigarettes while others are larger, box-shaped systems.

To vape, the user turns on the battery which heats the coil inside the atomizer. This vaporizes the e-liquid so it can be inhaled as a smooth, thick vapor cloud.

How Do They Work? Key Differences in Technology

While both provide an alternative to traditional smoking, IQOS and vaping have very different technologies heating either real tobacco or nicotine liquid.

Tobacco Heating in IQOS vs Liquid Vaporizing in Vaping

The core difference is IQOS heats specially designed tobacco sticks while vaping devices heat and vaporize liquid.

With IQOS, real tobacco is heated to 350°C through an electronically controlled blade inside the IQOS holder. This avoids combustion but still extracts nicotine and flavors from the tobacco.

Vaping devices use metal coils to heat and vaporize nicotine-containing liquids at around 200°C. No tobacco is present in vaping devices. The user inhales the resulting vapor.

Temperature Differences

The optimal temperature to extract flavors and nicotine from tobacco in IQOS is much higher, around 350°C, compared to 200°C to vaporize liquids in vaping devices.

However, both stay well below the 600-900°C burning temperature of cigarettes to avoid combustion and associated toxins.

Role of Electronics and Batteries

Both IQOS and vaping devices rely on electronics and batteries to power the heating components.

The IQOS holder contains the electronics and rechargeable battery to precisely control the heating blade and temperature. The holder must be periodically recharged in the IQOS charger.

Vaping devices also have integrated rechargeable batteries to provide consistent power to the metal heating coils that vaporize the liquid. The atomizer and battery are combined seamlessly into a single vaping device.

User Experience Comparison: IQOS vs Vaping

While the underlying technology differs, both IQOS and vaping aim to offer a satisfying alternative to conventional cigarette smoking. But the user experience still varies in areas like taste, throat hit, vapor production, and convenience.

Taste and Flavor

One of the main differences between IQOS and vaping is in the tastes and flavors available.

With IQOS, you are limited to the tobacco flavor profiles offered in the IQOS tobacco sticks. There are menthol options along with a range of blends marketed as crispy, woody, etc. However, you are still fundamentally limited to tobacco flavors.

Vaping opens up a huge range of e-liquid flavors that go far beyond tobacco. Thousands of flavors exist, from fruity and dessert flavors through to cinnamon, menthol, coffee, and more. The flavor possibilities are endless with vaping.

So vaping offers much more customization and variety around taste. IQOS offers a more traditional tobacco experience in terms of flavor.

Throat Hit

The throat hit refers to the sensation you feel when inhaling the vapor or smoke into your throat and lungs. Both IQOS and vaping try to mimic the throat hit of cigarettes to provide satisfaction.

The tobacco vapor produced by IQOS contains nicotine and aims to closely replicate the throat hit of traditional smoking with a prickly heating sensation.

Vaping throat hit depends more on the PG/VG ratio of the e-liquid along with the nicotine content. Higher PG and nicotine levels make the throat hit stronger and harsher like a cigarette. Lower levels soften the sensation.

Vapor Production

There are some visible differences in the volume and density of the vapor produced by IQOS and vaping.

The tobacco vapor from an IQOS tobacco stick tends to be lighter and dissipate more quickly than vapor from vaping. The thinner vapor makes it less obvious to others around you when using an IQOS device.

Vaping can produce thick, dense clouds of vapor, especially when using high VG e-juice blends. Trick vaping plays into producing massive vapor clouds. But for new vapers, this effect can be dialed down by choosing a lower VG liquid.

Convenience and Use

Both vaping and IQOS aim to offer satisfying alternatives that are convenient and easy to use throughout the day. However, there are some convenience differences.

The IQOS holder, charger and tobacco sticks allow a user experience much closer to traditional cigarettes. You insert a tobacco stick like a regular cigarette and can quickly take puffs when craving nicotine. No refilling or prep is required.

However, the IQOS holder itself is bulkier than a cigarette. You also need to periodically recharge the device and carry tobacco sticks.

Vaping devices are highly portable and convenient, especially pod vapes. However, you either need to refill liquid or swap out cartridges/pods throughout the day. This takes more hands-on maintenance than IQOS.

For convenience, vaping devices win for portability while IQOS mimics the quick, simple use of cigarettes.

Health and Safety: How Do They Compare?

Avoiding the harmful combustion products associated with cigarette smoke is a key goal of both IQOS and vaping. But there are open questions around the long-term health and safety impacts of extended use.

Tobacco Heating vs Vaporizing

The core difference that may impact relative risk is that IQOS heats actual tobacco while vaping vaporizes nicotine liquid.

Heating rather than burning tobacco aims to reduce exposure to tar and combustion-related toxins. And evidence does suggest IQOS emits lower levels of harmful chemicals than cigarette smoke.

However, compounds in tobacco like nicotine are still present. Other safety concerns like secondhand exposure from the IQOS vapor exist. More research is needed on potential long-term impacts.

Conversely, vaping avoids tobacco entirely by vaporizing nicotine liquid. This provides a pure delivery of nicotine without tobacco exposure. But the long-term health effects of prolonged inhalation of vaping ingredients remain unknown.

Open Questions Around Safety

Both products are relatively new to market compared to cigarettes with decades of research. So gaps in scientific data on long-term health and safety remain.

For IQOS, questions include:

• Are lower toxin levels reduced enough to meaningfully impact health outcomes versus cigarettes?
• Does heating tobacco introduce any new risks not seen with traditional smoking?
• What are the risks of secondhand exposure to IQOS vapor?

For vaping, open questions include:

• Are vaping devices safe for long-term, daily use for many years?
• What are the health impacts of inhaling PG, VG, and flavorings over time?
• How do factors like nicotine content and vaping style impact risks?

While considered safer alternatives, neither can be deemed conclusively safe based on current research. Close monitoring of emerging evidence is warranted.

Other Safety Factors

Other general safety factors are common to both IQOS and vaping:

• Risk of poisoning or burns from improper handling of liquid (vaping) or tobacco sticks (IQOS).
• Potential battery issues leading to overheating or explosions.
• Nicotine addiction remains a risk with both products.

So care must be taken with use, storage, and charging of either product. And nicotine levels should be tapered down over time to avoid prolonged dependence.

Cost and Affordability Comparison

A final point of comparison is how the costs of using IQOS and vaping products differ, both short-term and long-term.

Upfront Device Costs

One advantage of vaping from a budget perspective is that many quality entry-level vape starter kits can be purchased for $20 to $50. Even advanced mods and pod systems range from $50 to $100 in most cases.

In contrast, purchasing the IQOS holder, charger and accessories averages around $100 just to get started. The IQOS price point is more comparable to midrange vaping kits.

So vaping devices themselves tend to be less expensive upfront. However, tanks, coils and batteries do require replacement over time which adds costs.

Consumable Comparison

The ongoing cost of consumables – e-liquids versus tobacco sticks – is where the cost difference narrows when comparing vaping and IQOS.

A pack of 20 IQOS tobacco sticks costs around $6 to $9 in most markets, similar to premium cigarette pricing. However, due to the shorter length, each stick equates to around one traditional cigarette.

The cost per 30mL bottle of e-liquid for vaping varies widely based on brand and nicotine strength but averages around $15 to $25. At 5mL per day, one bottle would last around a week.

Factoring in device lifespan and maintenance costs, the total ongoing costs can ultimately average out to a similar level between vaping and IQOS products. Vaping offers more ability to fine-tune consumption and flavors to control costs. But both represent an ongoing, non-trivial expense for daily users.

Cost Savings versus Smoking

The most important cost consideration for smokers is that both IQOS and especially vaping offer significant potential savings versus the average $280+ per month spent on traditional cigarettes.

Switching to vaping or IQOS can cut this monthly cost in half or more. So while not cheap, they still provide an opportunity to reduce smoking expenses substantially.

Frequently Asked Questions (FAQ)

Is vaping definitely safer than IQOS?

No, it’s not definitively proven as safer at this point. Both products avoid combusting tobacco, which aims to reduce exposure to many toxins and chemicals compared to cigarette smoke. But the long-term health impacts of prolonged vaping or IQOS use still require further research over many years to truly understand relative risk. Both products should be considered alternatives that likely carry lower risk, but conclusive evidence is still lacking.

Can you use IQOS indoors?

Many indoor public spaces prohibit both vaping and IQOS. However, the odor and vapor dissipate more quickly with IQOS compared to cloud-producing vapes. Some private establishments may allow IQOS in designated areas since the vapor is less obvious and intrusive. But there is no guarantee IQOS can be used freely indoors.

Does IQOS cause “popcorn lung”?

There are no links reported between IQOS and popcorn lung (bronchiolitis obliterans). This condition has been conjectured with diacetyl flavorings in some vape liquids but not definitively proven. IQOS does not rely on added flavorings but rather heats real tobacco. There is no evidence it poses a risk for popcorn lung at this time. As with any product, risks linked to long-term use are not yet certain.

Can non-tobacco vape juice be used in an IQOS device?

No. The IQOS system is designed specifically for their proprietary tobacco sticks. The heating blade reaches temperatures calibrated to properly heat the specially formulated tobacco blend in the sticks. E-liquids could release toxic chemicals if heated to these temperatures. Vape juices should only be used safely in appropriate vaping devices designed for liquid vaporization. IQOS should only use authorized tobacco sticks.

Is it possible to smoke cannabis in an IQOS?

No. Only legal, approved tobacco sticks should be used in the IQOS holder. Attempting to smoke cannabis, THC oil, or other unauthorized substances in an IQOS device would be extremely hazardous. Like vaping devices, IQOS reaches high temperatures that can release toxic chemicals from plant matter. Cannabis should only be smoked in appropriate devices designed explicitly for that purpose.

Key Takeaways: IQOS vs. Vaping

• IQOS heats real tobacco while vaping vaporizes liquid containing nicotine, flavorings, and humectants like PG/VG.
• Both avoid combustion and aim to minimize exposure to cigarette toxins and tar.
• Vaping offers far more customization of flavors and experiences; IQOS is limited to tobacco blends.
• IQOS mimics the convenience and experience of traditional smoking more closely.
• Relative long-term impacts on health and safety are still subject to ongoing research for both products.
• Vaping starter kits are generally more affordable; ongoing consumable costs are comparable.
