Yes, 20mg vape liquid (20mg/ml) is considered a high nicotine strength, typically recommended for heavy smokers (over a pack a day) to manage strong cravings, offering significant nicotine delivery, especially with smooth-hitting nic salts, but it's the legal maximum in places like the UK, ideal for transitioning from cigarettes.
Approximately 10-15 vape puffs are equal to a cigarette, although nicotine absorption may differ between smoking and vaping.
The most common option is a 20mg strength vape, which is the highest available in the UK. The next step down is a 10mg vape, and after that, the option is a nicotine-free vape. Begin by incrementally reducing your nicotine strength. Each step should be maintained for 2-4 weeks to allow your body to adjust.
1 ml of 20 mg/ml nicotine strength e-liquid is roughly equivalent to 20 cigarettes a day. From this, you can work out what strength e-liquid you should buy for your vape so you're getting enough of a nicotine hit.
How long this lasts depends largely on nicotine strength and how you vape. For example, a prefilled pod of nicotine salts at 20 mg/ml may deliver between 275 and 600 puffs. A heavy user might go through one in a single day, while a light user could stretch the same pod across two or even three days.
Yes, lungs can begin to heal and show significant improvement after 7 years of vaping once you quit, with inflammation decreasing and lung function improving, but the extent of recovery depends on the damage; the sooner you stop, the better the chance for healing, though extensive, long-term damage might be permanent, emphasizing the need to quit for the best possible outcome and consulting a doctor for persistent issues.
18mg or 1.8% and 20mg or 2% are the highest nicotine levels (suitable for heavy smokers on more than one pack a day). These levels will provide a similar throat hit as traditional cigarettes.
But vaping might actually be worse for your lungs.
Many people assumed this was a safer way to smoke. “Because of the chemical composition, vaping is similar to inhaling an acetylene welding torch,” explains Dr. Thau. “To make it more palatable, they add other chemicals.
Generally, the recommended daily limit for nicotine intake is around 20-30 milligrams (mg) per day. However, this can vary based on individual needs and the tobacco product used. Nicotine pouches typically contain between 2–15 mg per pouch, with most brands offering a range of strengths.
Scientists have estimated that using vaping products exclusively is about 95% less likely to result in death from tobacco use compared to smoking cigarettes. 95% less likely to result in death from a tobacco-related disease compared to smoking cigarettes.
Furthermore, any vaping product—regardless of whether it is disposable or rechargeable—that exceeds the Tobacco Products Directive (TPD) limits of 2ml e-liquid capacity or 20mg/ml (2%) nicotine strength is classified as non-compliant and illegal for sale.
Nicotine strength is typically measured in milligrams of nicotine per millilitre of e-Liquid (mg/mL), which refers to the amount of nicotine present in the e-Liquid. In Canada, the maximum nicotine strength allowed nationally is 20 mg/mL, making it a popular option for many and a standard in the industry.
In short — yes, it's considered strong. But strength isn't necessarily a bad thing. If you're a heavy smoker making the switch to vaping, a 20mg vape might feel just right. It's designed to mimic the nicotine hit you're used to, helping with cravings and making the transition smoother.
What Is Considered Heavy Vaping? While there is no definite metric to determine heavy vaping, using more than 10 mL of e-liquid or refilling multiple times a day is typically considered heavy vaping. However, the vapers used can add nuance.
While occasional vaping or smoking is generally less detrimental than regular daily use, it still has negative health effects. The risks associated with vaping and e-cigarette consumption include: Heart disease and high blood pressure. Respiratory tract infections and irritation.
What's worse, says Blaha, many e-cigarette users get even more nicotine than they would from a combustible tobacco product: Users can buy extra-strength cartridges, which have a higher concentration of nicotine, or increase the e-cigarette's voltage to get a greater hit of the substance.
Yes, your lungs can begin to heal from vaping as soon as you quit, with inflammation decreasing and lung function improving, but the extent and speed of recovery depend on the damage; while some issues resolve, permanent damage like scarring can occur, necessitating immediate cessation for the best chance at healing and seeking medical help for severe symptoms.
Yes, 20mg of nicotine is equivalent to 2% nicotine.

Because vaping is far less harmful than smoking, your health could benefit from switching from smoking to vaping. And you will reduce your risk of getting cancer. Switching from cigarettes to e-cigarettes could also save you a lot of money.
Evidence shows that vaping is less harmful than smoking. Vaping exposes users to fewer toxins and at lower levels than smoking cigarettes. Switching to vaping reduces your exposure to toxins that can cause cancer, lung disease, and diseases of the heart and circulation like heart attack and stroke.
Research on smoking has shown that nicotine is highly addictive. Someone who uses vapes may become addicted to nicotine and find it difficult to stop using it. You can become addicted to nicotine within days of starting to use it, even if you only vape occasionally.
A 20mg vape typically generates 1mg of nicotine for each puff, so 10-20 puffs may be equal to the nicotine intake of a single cigarette. This number can vary obviously, depending on individual vaping habits and device efficiency.
How long does nicotine stay in your body? Nicotine itself is typically metabolized and cleared from the bloodstream within 1-3 days after the last use. However, its metabolite, cotinine, can remain detectable in the body for up to 10 days in blood and saliva, and even longer in urine and hair follicles.
Start Slow When Reducing Your Nicotine Intake
The best approach is to step down gradually. If you're on 20mg nic salts, try dropping to 10mg first. Once you're comfortable, move to 5mg. From there, switching to a 3mg freebase or shortfill feels much easier.
