Hi, I have been vaping for 2 weeks and have only had 3 fags in that time! I have developed a severe sore throat, so painful I can't swallow! I am using hangsen 70/30 liquid. Someone suggested trying a liquid higher in vg so I ordered some 30/70 vg liquid. 2 hours after using the new e liquid, the plastic mouthpiece cracked and broke on my smok aro. The same happened on my spare aro. I have gone back to hangsen liquid and have a major sore throat. I am drinking loads. Is it just because of giving up smoking or the vaping process please. Thanks x
