Q: What does mg/mL mean in nicotine strength?
It's the concentration of nicotine in the e-liquid: milligrams of nicotine per milliliter of liquid. A 6 mg/mL bottle has 6 milligrams of nicotine in each milliliter. Higher numbers mean stronger liquid.
Q: How do I choose the right nicotine strength if I'm switching from cigarettes?
Think about how many cigarettes you smoked per day. Heavy smokers (more than a pack a day) often start with 35-50 mg/mL nicotine salts. Moderate smokers (half to a pack) might do well with 12-20 mg/mL. Light or occasional smokers usually prefer 3-6 mg/mL. Start there and adjust.
Q: What's the difference between nicotine salts and freebase nicotine?
Freebase nicotine is the traditional form—it's harsher on the throat, so it's used in lower strengths (3-18 mg/mL). Nicotine salts are chemically modified to be smoother, allowing much higher strengths (25-50 mg/mL) without harshness. Salts are common in pod systems, freebase in sub-ohm tanks.
Q: Can I mix nicotine strengths to get a custom level?
Yes, you can mix two e-liquids of the same flavor and brand to get an in-between strength. For example, mixing equal parts of 3 mg and 6 mg gives you 4.5 mg. Just make sure the flavors match, or you'll dilute the taste.
Q: What should I do if the nicotine strength feels too strong?
If you feel dizzy, nauseous, or get a headache, you're getting too much nicotine. Step down to a lower strength—for example, from 50 mg to 35 mg, or from 12 mg to 6 mg. Also, take smaller puffs and wait a bit between them.
