Well, I think can be dangerous for health. But it all depends of what you are vaping exactly. Nicotine is very toxic thing. And overdose of nicotine can cause many problems. Even cancer,dude. I was smoking before, and then I switched it to vaping. But after few months I understand that I am addicted to the process, but not to the nicotine. That helped me a lot. I just stopped consuming nicotine at all and found out cbd vape juices
www.knockoutcbd.com. This stuff is different. I like the effect, it is better and more relaxing.
