Vaping and smoking deliver the same drug-nicotine-through different mechanisms. The downstream receptor pharmacology (nAChR binding, dopamine release) is identical. But the delivery characteristics differ enough that the withdrawal and cessation experience diverges meaningfully.
Delivery Efficiency
Cigarette smoke delivers nicotine over 5-8 minutes, with blood nicotine levels peaking 10-20 minutes after lighting. The ritual is time-constrained: a cigarette has a beginning and an end.
Nicotine salt formulations (used in most modern vapes) deliver nicotine more rapidly and at significantly higher concentrations. High-concentration nicotine salts (50mg/mL, equivalent to about 5% nicotine) can match a cigarette's nicotine delivery in 2-3 puffs. Pod devices are typically kept available at all times, creating a continuous supply with no natural endpoint.
The result: vapers tend to use more frequently, in more contexts, with less conscious awareness of each use event. A cigarette is a 7-minute ceremony. A vape hit takes 3 seconds.
The Frequency-Dependence Implication
Higher use frequency = stronger behavioral conditioning. Every context in which vaping occurs becomes a conditioned cue. For heavy vapers:
- At a desk (conditioned)
- In the car (conditioned)
- Post-meal (conditioned)
- During video calls (conditioned)
- Before sleep (conditioned)
- First thing upon waking (conditioned)
Cigarette smokers have fewer conditioned contexts because use is limited by the ritual duration and social acceptability constraints (you cannot smoke at a desk or on a video call). Vapers have far broader contextual conditioning.
This means behavioral craving in ex-vapers is typically more pervasive and context-diverse than in ex-smokers.
The Nicotine Load Difference
Standard cigarettes deliver 1-2mg of absorbed nicotine per cigarette. A 20-cigarette-per-day habit delivers 20-40mg of absorbed nicotine.
Heavy vapers using high-concentration salt nicotine often consume nicotine equivalents far in excess of this, sometimes without realizing it. The pharmacological dependence established by heavy vaping may be stronger than typical cigarette dependence.
Cessation Implications
For ex-vapers:
- The behavioral component requires more work: More contexts to address, more substitution strategies needed, more triggers to identify and manage
- The pharmacological dependence may be stronger: Dose cytisine according to craving intensity, not cigarette equivalents
- The 72-hour acute phase may be more intense: Higher baseline nicotine levels create a steeper drop
The NIC protocol was designed to address both smoking and vaping cessation. The behavioral substitution tools included are specifically relevant for vapers. The cytisine dosing is effective across both dependence patterns.
What Is the Same
The receptor pharmacology is identical. The dopamine deficit in weeks 2-4 is identical. The nAChR upregulation that produced dependence operates through the same mechanism. The strategies that address receptor-level withdrawal (cytisine, NAC, L-Theanine) work regardless of delivery mechanism.
If you quit vaping, use the same protocol as if you quit smoking. The pharmacological support is the same. Add extra attention to behavioral trigger mapping.
