Hi guys, have a question maybe someone here can help. All but one of my juices are lower nic levels. I have been having anxiety latley (nothing to do with ecigs it is normal for me to have this) but I am wanting to up the nic level in a few of my juices to accommodate) Is there a way I can calculate how to make a 11mg or a 18mg to a 24 mg by adding nic juice?
