Nope, I wouldn't either. I usually vape 12 mg nic juices but I kep a tank of 18 mg on hand just in case of emergencies - you're much better off (and safer) doing something like that.
If you're particularly keen on the idea of a nicotine hit like you used to get with ciggies then it might be worth looking into nicotine salts - there are a few threads on the forum if you do a search.
