Juul did help me quit smoking, which was a miracle. Soon after, i started to find myself with vape in hand all day. I started getting a deep ache in my chest, numbness in my hands and arms, as well as my face at times, and shortness of breath. I decided to quit Juul 4 weeks ago and finally starting to feel better. I think Juul could be a great tool in quitting smoking when used in a controlled way (Perhaps prescribed by a doctor) as it erased any desire to smoke cigarettes again.
