How much nicotine do HEETS contain, compared to classic cigarettes


Frequently asked question by IQOS users is about the content of nicotine in HEETS cartridges. Compared to normal smoking, it is a bit less, but a similar dose is still flowing into the body.

In addition to the demonstrably reduced content of pollutants in IQOS, the most important thing for tobacco users is how much nicotine gets in the body. This highly addictive drug causes the body to calm down and creates a pleasant feeling.

All HEETS variants contain the same amount of nicotine, 0.5 mg, the difference is only in taste.

Unlike burned tar, it probably does not cause major damage, but its effects have a short-term impact on narrowing of the blood vessels and stimulation of the heart, thereby increasing blood pressure, stimulating the digestive tract and accelerating metabolism.

The amount of nicotine in tobacco

A classic cigarette contains from 0.3 mg to 0.8 mg of nicotine but most of it is burned and “only” about 20-50% is absorbed into the body. According to the manufacturer, HEETS contain 0.5 mg nicotine (what do HEETS contain), but IQOS only heats them up and therefore nicotine is absorbed significantly more. Therefore, you should be careful not to increase your addiction. Also when you get too much nicotine into your body it could cause a headache, stomachache, and nausea.

Label  Nicotine (mg)  Tar (mg) Carbon Monoxide (mg)
HEETS for IQOS 0,5 > 0,0005 N/A
NeoStick for GLO 0,3 > 0,001  N/A
Karelia Slims 0,3 3 2
L&M Silver 0,4 4 5
Marlboro Gold 0,5 6 6
Marlboro Red 0,8 10 10

User reactions

The table shows that there is enough nicotine in HEETS to feel satisfied when you switch to it from cigarettes. HEETS not only contain a comparable amount of nicotine but also provide a greater dose of it due to its more effective release.

So it is strongly recommended that IQOS users, especially in later months of use, follow old rituals, use HEETS in similar or lower amounts. Those who did not smoke at home and used to go to the balcony should maintain their habits, as there is a real risk of increasing addiction.
