Hi. Thanks. The ejuice I have says it can cause cancer, I don't know why. I bought some hemp oil instead and feel it's safer. My vape device is screwed up. I went to the web site of the mfg. and they gave me some tips to see if they work. Going to try them but not with the hemp oil since it leaks. I'm trying to lose weight, smoking cigs is disgusting. Just went through a pack and they don't do anything for me any more. Just a bad habit. Trying to get back to vaping.
