“Can a Juul help me stop smoking?”

A lot of people use e-cigarettes for this purpose. If you are serious and are dilligent about tapering the concentration of nicotine in the cartridge, many people have had luck.
HOWEVER- vaping is NOT FDA approved for smoking cessation and the vapor can be harmful to your lungs and windpipe all by itself. Therefor I don't recommend it. Conventional nicotine replacement with a system of gradually decreasing strength patches, nicotine gum or lozenges are more reliable. Chantix (varenicline) is also very effective but has to be prescribed and has some side effects that your doctor should discuss with you. Good luck

Given the fact that stopping any addiction is not a passive thing, it is my opinion, that Juul could help only if you make a weaning plan and stick with it to the letter. If there is no plan you are just replacing smoking tobacco with smoking Juul.

Vape products are supposed to help people get off cigarettes. Most people feel they are good for this. The problem is that people, especially young people, are using them to get into nicotine which is not good.

Some people have been able to reduce their cigarette consumption with e-cigarettes (I'm not sure brand matters) and a few have been able to stop completely. The science isn't clear on the safety of e-cigarettes, and the liquid inside often contains small amounts of cancer-causing chemicals. But it's much less toxic than a regular cigarette, and you're not inhaling all the microscopic ash that destroys lungs. You might get better results with nicotine replacement using a nicotine patch plus something that will give you a quick nicotine hit when you're craving a smoke. I like nicotine lozenges like Commit for this extra burst of nicotine. These are all over-the-counter and don't require a doctor's prescription. Prescription-only medications probably work better and include Revia (bupropion) and Chantix. If possible, you'll probably have better results if you work with your doctor to stop smoking. And don't forget that managing your stress is a skill you can learn. You're not stuck with using a chemical to calm down.

It may help you switch from a combustible form of nicotine abuse to a non combustible form but you are still addicted to the nicotine in the product. Seeking assistance for complete cessation is recommended.
