When you buy a "6mg" pouch, you assume you are getting 6 milligrams of nicotine into your system. But science is a bit more complicated than that.
Understanding what "mg" actually represents helps you dose correctly and avoid getting sick.
Total vs. Absorbed Nicotine
The number on the can (e.g., 6mg) refers to the Total Nicotine Content inside the pouch material.
However, you do not absorb 100% of that nicotine. The Bio-availability (absorption efficiency) of oral pouches is typically between 30% and 50%.
- Zyn 3mg: You likely absorb ~1.5mg into your blood.
- Zyn 6mg: You likely absorb ~3mg into your blood.
Comparison context
- Cigarette: Contains ~12mg, but you only absorb ~1.5mg from smoking it.
- Vape: A 50mg/ml salt nic is extremely potent per puff.
This explains why a "6mg" pouch feels roughly equivalent to smoking one or two strong cigarettes over the course of an hour.
Factors Influencing "Perceived Strength"
Two pouches can be rated 6mg but feel completely different. Why?
- Moisture: Moist pouches dump nicotine fast (high peak). Dry pouches release slow (low peak, longer duration).
- pH Level: Higher pH = Faster absorption = Stronger "Kick."
- Surface Area: A larger pouch touches more gum tissue, absorbing more nicotine at once.
The "Free-Base" Factor
Most pouches use Nicotine Salts (Bitartrate), which are stable and absorb smoothly. Some older products used Free-Base nicotine, which is much harsher on the throat but hits the brain faster.
People Also Ask
Is 6mg a high dose?
It is "Medium-High" for a new user, but "Standard" for a former smoker. It is not considered an "Extreme" dose.
Can I overdose on 3mg?
It is very hard to overdose (toxicity) on 3mg unless you are a child or have zero tolerance. You might feel dizzy, but actual toxicity requires higher loads.
FAQ
Why do European pouches go up to 50mg?
Different regulations and culture. The US market generally caps around 15mg for safety and liability reasons.
Does the mg lower as the pouch gets old?
Nicotine is volatile. If the can is open and exposed to air/heat for months, the potency will degrade.
