Answer these 5 questions to assess your level of addiction to cigarettes:
| Please rate your addiction to cigarettes on a scale of 0–100 | 0 = I am NOT addicted to cigarettes at all 100 = I am extremely addicted to cigarettes Addiction: 0–20 = 1 point 21–40 = 2 points 41–60 = 3 points 61–80 = 4 points 81–100 = 5 points |
| On average, how many cigarettes do you smoke per day? | Cigarette/day : 0–5 = 1 point 6–10 = 2 points 11–20 = 3 points 21–29 = 4 points 30+ = 5 points |
| Usually, how soon after waking up do you smoke your first cigarette? | Minutes : 0-5 = 5 points 6–15 = 4 points 16–30 = 3 points 31–60 = 2 points 61+ = 1 point |
| For you, quitting smoking for good would be: | Impossible = 5 points Very difficult = 4 points Fairly difficult = 3 points Fairly easy = 2 points Very easy = 1 point |
| After a few hours without smoking, I feel an irresistible urge to smoke | Totally disagree = 1 point Somewhat disagree =2 points Neither agree nor disagree = 3 points Somewhat agree = 4 points Fully agree = 5 points |
Now add your points (maximum=25)
Interpretation :
5-10 points: Low level of addiction
11-15 points: Moderate level of addiction
16-20 points: Strong level of addiction
21-25 points: Very strong level of addiction
Our previous research found that a value of 16 or above indicates that your are strongly addicted to cigarettes.(a)
This questionnaire is called the Cigarette Dependence Scale (CDS-5), it is a well-validated measure of dependence.(b)

Answer these 5 questions to assess how much nicotine you consume as a smoker (or consumed when you smoked). We will then use this information to calculate the optimal nicotine concentration in your e-liquids, your nicotine medications (patch, gum, tablet, inhaler), or your nicotine pouch. Our statistics show that these 5 questions provide twice as accurate an estimate of your nicotine need as using only the number of cigarettes smoked per day.
1- How many cigarettes do (did) you usually smoke(d) per day?
2- Usually, how long after waking up do (did) you smoke your first cigarette of the day?
3- On a scale of 0 to 100, indicate how heavily you smoke(d):
4- On a scale of 0 to 10, how much smoke do you inhale each day (or inhaled when you smoked)? This amount depends on the number of cigarettes you smoke, how deeply you inhale, and the number of puffs.
0: I do not inhale any smoke.
10: I smoke so much that even if I tried, I could
not inhale any more smoke.
5- Indicate the number of milligrams of nicotine listed on your cigarette packet:
Now, add up and calculate your total number of points (maximum = 25 points)
Data from our studies indicate that if your total is:
After you stop smoking, you must continue to absorb the same amount of nicotine in order to avoid withdrawal symptoms and not start smoking again because you cannot tolerate these symptoms. Consume enough nicotine from e-cigarettes or from nicotine medications or nicotine pouches for at least 3 months after quitting smoking.
Nicotine replacement medications release approximately 70% of the nicotine they contain. For example, a patch containing 21 mg of nicotine releases approximately 15 mg of nicotine.
Use this factor (x0.7) to calculate the optimal dose of your nicotine medication. For example, if you scored 12 points on our questionnaire, you need 17 mg of nicotine per day, and a 21 mg patch plus two 2 mg gums should provide you with the necessary dose.
Use the same rule (x0.7) as for nicotine medications.
For e-cigarettes, the amount of nicotine aborbed by the user depends on many factors, in addition to the nicotine concentration in the e-liquid:
Nevertheless, our previous studies conducted among former smokers who successfully quit smoking using e-cigarettes, and who responded to the above questionnaire offer some insights.
Vapers who obtained :
Use these results as a guide to choose your e-liquid, and do not underdose your e-liquids, because if you do, you risk unnecessarily:
The right dose of nicotine is the one that eliminates nicotine withdrawal symptoms. Your brain acts like a thermostat, regulating the amount of nicotine you need. If you use e-liquids that do not contain enough nicotine, you will need more liquid to feel satisfied.
There is no risk of nicotine overdose in regular smokers, as they can tell when they are consuming too much nicotine (specific taste in the mouth, sensation similar to that felt when you have smoked too much).

When you stop smoking, your body no longer gets its dose of nicotine, and it’s normal to feel uncomfortable. Here are the withdrawal symptoms you may experience:
These symptoms are most intense during the first few hours and days after your last cigarette. After the first few days, these feelings diminish significantly, but be aware that some signs may last longer:
The graph below, taken from one of the author’s scientific publications, shows how the intensity of withdrawal symptoms changes during the first year after quitting smoking. The most striking feature is that appetite and weight gain increase, while the intensity of all other symptoms decreases over time. The symptom that decreases most rapidly in intensity is craving, i.e. the strong urge to smoke. The intensity of all symptoms changes most rapidly during the first 30 days after quitting smoking. AFter about 6 months, symptoms remain stable.
