What nicotine strength should I choose?
Choosing your dosage is like picking a shoe size: if it’s too small, it hurts; if it’s too big, you’re swimming in it. If you smoked a pack a day, go for 12 or 18 mg/ml. If you were just a light social smoker, 3 or 6 mg/ml will be plenty to keep you from hitting the ceiling.
The dosage depends on your nicotine dependency and your gear. In MTL (tight draw), high levels are used to satisfy cravings. In DL (cloud chasing), levels are drastically lowered (often to 3 mg) because the massive vapor volume increases the total nicotine absorbed per puff.
