Hi there. I have three questions which has been seeked for since I started to vape, but haven't found answers yet. So I post them here with the hope to find some anwers. 1. I fill my cartos 4 times daily, which 40 drops of VG + 10 drops of 36mg nicotine each time, so that I vape 40 drops = 2ml 36mg = 72mg nicotine daily. I had been smoking for 10 years with more than 2 packs daily. If compares to smoking 1mg cigarette, does that mean vaping 72mg nicotine daily is somewhat equal to smoke 72 cigarettes 1mg daily? And is vaping 72mg nicotine daily high? And if can, pls tell me how much you vape daily. 2. I'm going to have a Ego C vv twist. Its Voltage ranges from ~3-4.8V, the question of a vv PV is, if it works at 3V, will the battery life be longer than working at 4.8V? 3. How can I register an national forum? Thanks alot!
