Vaping Explained:
Battery Safety, Sub-Ohm Setups, Health Studies and FDA Rules

CigBuyer explains how e-cigarettes work, how to handle batteries and e-liquid safely, what the research says about vaping and health, and how US vaping law has changed. Written for adult smokers, 21 and older in the US. Vaping is not risk-free, and it is not for non-smokers or anyone under 21.

Lower resistance and higher power ask more of your batteries. These guides explain Ohm's Law, amp limits, TC wire types and coil care before you build or buy.

The Basics of Sub-Ohm Vaping

Sub-ohm vaping means using coils under 1 ohm for more vapor. Learn how Ohm's Law, airflow and battery discharge limits keep your setup safe.

Straight answers to common questions

Short answers quoted from our guides. Each links to the full explanation and its sources.

Are e-cigarettes safe?
No nicotine product is completely safe, but e-cigarettes are far less harmful than smoking for adults who switch completely. What is known and unknown about e-cigarette safety →
How many puffs of a vape a day is safe?
No health agency sets a safe daily puff count. The CDC says there are no safe tobacco products, including e-cigarettes, and people who don't use tobacco should not start. Tracking nicotine instead of puffs →
What is sub-ohm vaping?
Using a device with an atomizer resistance below 1 ohm. Lower resistance draws more current from the battery, so never exceed the amp limit of your batteries, which could lead to a fire or explosion. Sub-ohm basics and battery limits →
Does temperature control measure coil temperature?
No. The mod estimates it from changes in the coil's resistance, which is why temperature control needs nickel, titanium or stainless steel wire and the correct wire type set on the mod. How temperature control vaping works →
How dangerous is e-liquid to children?
A single teaspoon (about 5 ml) of 1.8 percent e-liquid holds about 90 mg of nicotine. Even a small bottle can seriously harm a child. If someone swallows e-liquid, call Poison Control at 1-800-222-1222 or 911 right away. Nicotine poisoning symptoms and safe storage →
