If you're using 12mg nic in a dripper instead of a tank, it may be too harsh. Some people, when initially trying to switch from cigarettes to vaping, need higher 12mg or 24mg nicotine levels to more closely mimic the nicotine delivered from the traditional cigarettes. After some time vaping at this level, you should try to reduce to 3mg or 6mg nic levels. This 12mg level is pretty high, so we suggest you do not use it in an RDA as it will be harsh. It should be fine in vape tanks, but you'll get quite a throat hit. Again, if you're at this nic level, think about working your way down toward lower nic levels of 6mg or 3mg. Eventually, you may be able to get to the lowest nicotine level (1.5mg nic), or even 0mg nic.
