Aye, in a perfect world I would not vape or smoke. But I made that mistake 14 years ago.
It is true that there is no long-term research in the dangers of vaping. But in the last ten years, any reputable doctor will tell you that switching to vaping is extremely wise.

Nicotine is a powerful drug. I salute those that have been able to stop. But for millions, stopping nicotine is similar to fasting, after a few days your brain is screaming for nicotine, and it leaves you unable to think. Not to mention headaches, puking, cold sweats, and wanting to murder people.
