I mix my own eliquid. And work with 60mg nic. I put 6ml of nic to make a 30ml bottle of 12mg. Heres my question : After putting in the vg and pg and nic into a 30ml bottle and giveing it a quick 15 or so second shake is it safe to vape right away ? Or does it need time to mix, im afraid of vapeing it immediatley and getting more nicotine then pg or vg in my tank and getting sick or worse. Also after quick shakeing if i dont vape it right away and let it sit on a table or something with the bottle cap ON. Do the pg and vg and nicotine seperate where i could have that problem ? Or is it good to vape? Is it nessisary to shake the bottle everytime or every so many days ? Im a hypocondriac and just want to make sure. Thanks everybody
