What is the best e-cigarette for a heavy smoker?

Have you been smoking more than 15 to 20 cigarettes every day for several years? Have you tried to quit smoking, but the first cigarette of the morning causes you to relapse?

Heavy smokers often encounter the greatest difficulties in quitting tobacco. Fortunately, the e-cigarette can be an effective solution — provided you choose the right equipment.

Let's discover together the best e-cigarette for a heavy smoker and the essential tips to help you successfully make the transition.

Why does a heavy smoker need to choose a suitable e-cigarette?

The specific needs of heavy smokers

When you smoke the equivalent of a pack of cigarettes per day for several years, the addiction becomes both psychological and behavioral. It is therefore crucial to have a reliable, practical, and high-performing e-cigarette to accompany you throughout the day.

The choice of e-liquid is also essential: it must be well suited to your needs to optimize your smoking cessation.

The importance of the right equipment for a successful transition

Your first e-cigarette must meet several essential criteria:

• Durability; 
• Battery life; 
• Intuitiveness; 
• Convenience;
• Capacity. 

An "all-terrain" kit is ideal to keep up with your pace without a hitch. To this end, manufacturers compete in innovation to offer devices perfectly suited to heavy smokers wishing to quit traditional cigarettes. There's no need to necessarily opt for the best expert e-cigarettes; you can very well go for the best e-cigarettes around 50 euros or less.

The impact of nicotine levels on smoking cessation

A high nicotine level is often necessary to compensate for the effect of a traditional cigarette. It is recommended to choose an e-liquid rich in nicotine or nicotine salts for fast and effective absorption from our range of e-cigarette e-liquids.

Criteria for choosing the best e-cigarette for a heavy smoker

Battery life and capacity

In order to enjoy uninterrupted vaping throughout the day, it is best to opt for a minimum battery life of 1000 mAh. Of course, this can vary depending on the installed coil, as well as the choice of e-liquid and nicotine you will use.

Example:

If you opt for a 1.8 ohm coil (the least energy-consuming), with a 20 mg/ml e-liquid (the most "satisfying" nicotine level), then a 1000 mAh battery will carry you through a good part of the day without recharging.

Conversely, if you opt for a 0.5 ohm coil (which will require more power) with a 10 mg/ml e-liquid (which will require more consumption to satisfy you), then go for a battery of 2000 mAh or more.

Integrated batteries or removable batteries?

Today, most e-cigarettes offer a battery with an integrated cell that you can directly plug into a USB port. Less commonly, mod boxes offer a combination with a removable 18650 cell that is preferably recharged on a specific external charger. The latter offer excellent battery life of 3000 to 3500 mAh but require more maintenance. If you are new to vaping and are not comfortable with battery maintenance for vaping, opt for an e-cigarette with an integrated battery.

Tank type: clearomizer or pod?

While clearomizers have always existed, pod cartridges are increasingly popular for their practicality and cost-effectiveness. Let's look together at the differences, advantages, and disadvantages of these two types of tanks: 

• Clearomizer: Ideal for a larger e-liquid capacity and better battery life. They are generally found on large box-format kits. The advantage of the clearomizer is its durability. It is made of stainless steel with a pyrex glass tank (replaceable in case of breakage) and can last you several years while being adaptable, provided you maintain it well. Its disadvantage is the maintenance it requires. Indeed, you'll need to be comfortable with changing the coil every 2 to 3 weeks and also cleaning it regularly (at the time of coil replacement). Also, it can be heavier and bulkier than a pod cartridge.

• Pod cartridge: Practical, compact, and versatile, it appeared on the vaping market a few years ago to simplify the lives of vapers. Unlike the classic clearomizer, it is generally made from a heat- and nicotine-resistant plastic material.

There are several types of cartridges:

Empty cartridge: it is fitted with coils that will need to be changed every 2 to 3 weeks, just like a classic clearomizer. You can also fill it with the e-liquid of your choice.

Cartridge with integrated coil: it is designed for vapers who are not comfortable with changing coils. You will then need to replace it entirely every 2 to 3 weeks, and you can fill it with your e-liquid.

Pre-filled cartridge: this comes with an integrated coil and arrives pre-filled with e-liquid (you will have a choice of flavor and nicotine level). It is specially designed for beginners who do not want to handle coils or e-liquid. It is replaced once the tank is empty.

In short, what is the best option? 

The most durable and versatile option: certainly the clearomizer, which you can keep for several years and which will accompany you through your changes in nicotine level and even draw style.

The most economical option: undoubtedly the empty cartridge in which you'll need to change the coil. It can also prove to be versatile and adaptable depending on the installed coil.

The simplest option to start with: ideally the pre-filled pod cartridge, which requires no handling and no maintenance to begin vaping.

Power and settings: finding the right balance

A few years ago, heavy smokers were systematically directed toward large mod boxes where they had to study the settings, adjust the power (in watts), etc. Today, manufacturers compete in ingenuity so that settings are no longer an obstacle and power adjusts automatically.

So, out with the various power options (watts, temperature, volts, etc.) — if these still exist, it's the "automatic" or "smart mode" option that interests us for getting started without any fuss.

Especially since your device won't require much power and will need to adapt to a so-called "MTL" draw, similar to a traditional cigarette — low energy consumption and compatible with high nicotine levels.

Tight or airy draw? Indirect inhalation or direct inhalation?

One might think that a heavy smoker needs the most powerful machine possible, capable of delivering a lot of vapor. However, sub-ohm cloud machines — like shisha-style devices — are intended for vapers with low nicotine dependence. The reason? Their power and the volume of vapor delivered do not allow the use of an e-liquid with a high nicotine level without making the vaper cough. These large cloud machines are, however, good outlets for some heavy smokers who sometimes need an unrestricted draw. If you recognize yourself in this profile, the trick is to opt for the sub-ohm machine of your choice plus a small, affordable pod-format kit filled with 20 mg/ml nicotine salts to provide all the nicotine you need. You'll thus have the best of both worlds.

Compatibility with high-nicotine or nicotine salt e-liquids

If your tobacco dependence is high, using a high nicotine level is essential to maximize your chances of success. According to studies, using a nicotine replacement doubles or even triples the chances of successfully quitting smoking, especially among heavy smokers.

The cause is an excessive physical dependence that can lead to irritability, sleep disorders, fatigue, and above all an irrepressible urge to smoke (the famous craving), which could very quickly cause you to relapse.

Ideally, we will lean toward highly nicotine-rich products (up to 20 mg/ml). 

To accommodate a high nicotine level, your e-cigarette must be compatible with coils between 1.8 ohm and 1.00 ohm maximum. Beyond this limit, we are talking about sub-ohm (0.8 to 0.15 ohm) and the coil resistance will produce too much vapor to pair with a high nicotine dosage.

In terms of power, expect 8 to 25 watts maximum to suit this tight MTL draw.

Which e-liquid to choose with an e-cigarette for a heavy smoker?

Recommended nicotine level for effective cessation

Every smoker has their own sensitivity to nicotine, and heavy smokers are generally advised to take the highest dosage possible.

For this, European legislation allows a level of up to 20 mg/ml maximum (compared to 26 mg/ml before 2017). This dosage is ideal for regular heavy smokers looking for an effective solution that will make them forget their pack of cigarettes.

Sometimes, the craving for nicotine can be stronger even with 20 mg/ml. In that case, we advise you to seek your doctor's opinion — it's possible that you need an even higher dosage (and therefore a patch or an additional nicotine substitute).

How do you know if your nicotine dosage is right?

In the case of under-dosing: it is estimated that on average an MTL vaper (your case) consumes around 5 ml of e-liquid per day. If you consume more than 5 to 7 ml of e-liquid per day over several days and still feel a nicotine craving, it is very likely that your dosage does not suit you. Reconsider your dosage upward or add a nicotine substitute. 

In case of overdose: an e-liquid overdose can cause mild headaches, a feeling of nausea, and general numbness. If you experience these symptoms, put down your e-cigarette and drink plenty of water. If the symptoms don't disappear within 1 or 2 hours, seek the advice of your doctor or pharmacist.

Classic e-liquids vs nicotine salts: what's the difference?

E-liquids are products specially designed for vaping that contain pharmaceutical-grade nicotine. The latter can be of 2 kinds: 

• Classic e-liquids: classic e-liquids were the first to be formulated for vaping; they offer a gradual nicotine build-up with a strong throat hit. This very pronounced throat hit above 12 mg/ml may suit former smokers who prefer strong throat sensations. Good to know: if you experience a cough due to this throat hit, menthol flavor can help reduce the sensation. 

• Nicotine salts: arriving on the vape market in 2018, nicotine salts are specially designed for regular smokers. The nicotine contained in this product offers a much faster absorption than a classic e-liquid. Furthermore, its throat hit is also much smoother and far more pleasant for many smokers.

In terms of price, classic e-liquids are generally cheaper than nicotine salts. However, the cost per use of a salt will be lower since it allows you to vape less... but better. 

PG/VG: what ratio to choose for an optimal experience?

All e-liquids display a PG/VG ratio on their product page as well as on the bottle. This ratio measures the predominance of two essential ingredients that make up 99% of an e-liquid:

• Propylene glycol or PG: this product improves the fluidity of the e-liquid. It also helps carry flavors better and enhances the throat hit. More flavor-oriented, it produces little vapor.
• Vegetable glycerin or VG: this product, more viscous than PG, allows for more vapor production. However, it carries flavors less effectively and adds a sweet note.

The balance between these two products is therefore essential to obtain an e-liquid that won't leak, will produce clouds of vapor, and will preserve your coil from a burnt taste for a long time.

For MTL indirect inhalation equipment, ratios between 70/30 and 50/50 PG/VG are preferred. Below this, the product will be too thin and could leak through your coil. Above this, the product will be too thick and cause unpleasant dry hits (burnt taste). 

We therefore recommend:

• 50/50: Good balance between flavor and vapor production, for a kit with a coil resistance between 1.2 and 0.6 ohm requiring a slightly thicker e-liquid. 

• 60/40 or 70/30: For a smoother vape and better flavor rendition, for kits between 1.8 and 1.2 ohm requiring thin e-liquids. 

Tips for getting started with an e-cigarette as a heavy smoker

Successfully transitioning from tobacco to vaping without frustration

• Always have a charged e-cigarette and e-liquid on hand

Because in the early days you'll want to vape very often, don't hesitate to keep e-liquid refills, coils, or pod cartridges at home, at work, in your car, in your bags, etc. Overcoming cravings and preparing stocks of consumables for several days or even several weeks will reassure you and prevent you from relapsing back to cigarettes at the slightest burnt coil or dead battery. Likewise, plan for charging cables or an external power bank to recharge your e-cigarette at any time.

• Treat yourself with flavors

Because quitting smoking should not be a punishment, treat yourself by choosing and testing several flavors: mint, classic blonde, red fruits, exotic fruits, indulgent desserts. Flavors are there to keep you attached to your e-cigarette, but above all to make you regret even the smallest puff of your traditional cigarette. That cigarette will seem quite bland and much less enjoyable than you remember in the event of a relapse. 

• Vape more than you used to smoke

Even if this may seem exaggerated, it is nonetheless essential. The nicotine (classic or salt) contained in your e-liquid reaches the nicotine receptors in the brain more slowly than that of a smoked cigarette. Furthermore, its lifespan in the body is halved. This is why many vapers who have successfully made the transition feel like they vape much more than they used to smoke and have their e-cigarette "grafted" to their hand. This phase is transitional but necessary. Don't hesitate to vape more than necessary and take advantage of every moment outdoors to bring a little nicotine to your body. You will reduce your dependence on it in the following months.

• Change your habits and adapt your environment

Put away and hide all ashtrays, lighters, and packs that could remind you of your smoking past (visual triggers). Ideally, clean the clothes, bags, and fabrics in your home that might smell of tobacco, even when cold (olfactory triggers). If you're used to going to the bakery right next to your favorite tobacco shop, why not go to a better bakery a little further away? (routines and automatisms). Likewise, avoid drinks that could trigger the urge to smoke in the first few weeks: alcohol, strong coffee. These small details make an enormous difference throughout the day.

You can also adopt a smartphone app to help you quit, or pick up an excellent book about quitting smoking if the urge to light a cigarette arises. 

• Find support from other vapers

Finding support from caring people who accept your choice will be very helpful, especially during your first weeks of quitting. Even if your motivation seems unshakeable, your determination can be tested if you surround yourself with anti-vaping people or those who are too preachy on the subject. Protect yourself from these small irritations by cutting any debate very short or by choosing people around you on whom you can rely.

• Be kind to yourself and reward yourself

Don't blame anyone, especially not yourself in the event of a relapse. Guilt will not be your ally in quitting smoking (it may even be a feeling that led you to smoke in the first place). Turn every relapse into a new solution rather than an excuse. And above all, savor and reward every small victory: the first hours and then the first days without tobacco, the 3 flights of stairs climbed without being out of breath, your hands no longer smelling of tobacco, your complexion looking younger, etc. 

Maintaining your e-cigarette for better durability

Not all e-cigarettes require the same level of maintenance. Depending on the e-cigarette you choose, you will need to:

• Clean your equipment regularly: the best time to clean your equipment is when changing the coil. All parts of your e-cigarette, except the coil and battery, can be cleaned with warm soapy water and then dried with a soft cloth. For the battery, we recommend a clean, slightly damp cloth.

• Change coils according to the manufacturer's recommendations: on average, a coil (or a cartridge with an integrated coil) should be changed every 2 to 3 weeks at most. But this duration will depend on how often you vape and on the flavor of your e-liquid. Some vapers change their coils every week as soon as a burnt taste appears.

• Charge your battery at low power: to preserve its longevity, the battery of your e-cigarette should be charged as slowly as possible. The reason? Fast charging, although compatible with many models, will heat up your device. That's why a slow daily charge on a USB port of 1.0 A maximum is recommended.

Gradually adapting your nicotine level to reduce dependence

You've done it — you haven't smoked for a few weeks and it's time to think about progressively reducing your nicotine dependence. Before that, make sure not to skip any steps; the weaning period is your ally in avoiding relapses. Studies and doctors consider that a minimum of 6 months of nicotine replacement therapy (patches, gums, or medications) or smoking cessation aids is needed to obtain encouraging results over several years. While some smokers manage it in a few days, others take several months or years to be sure they've left tobacco far behind.

Ideally, this 6-month benchmark should be applied to quitting with an e-cigarette, even more so for a heavy smoker.

When you feel that your nicotine level has been fully satisfying you for several weeks, gradually reduce it for a gentle weaning process.
