Does it mean I'm allergic to nicotine If I hiccup from vaping sometimes? It only happens when I get a little or some juice from the drip tip in my mouth and swallow it Very rarely do I get them from just the vape. Just wondering If anyone else has ever experienced that or If I should be worried.
No - it doesn't mean you're allergic to nicotine. And yes, I have experienced that in the past, as have many others. Hiccups is nicotine's 'early warning alert' of too much nicotine. It's a 'precursor' to throwing up - again, nicotine's built in 'anti-poisoning' attribute - one of the few substances that actually does that. A 'close cousin' of nicotine is pokeweed which was used as a home remedy to induce vomiting.
Getting some nic on your lips/in mouth just shows how well it is absorbed by the skin/mucus membranes - and the ability to get a 'hit' without deep lung inhalation (vs. cigarettes) - another 'plus' for vaping.
That said, some clearos/tanks are better at not getting 'juice in the mouth'. If you're getting it a lot, you might consider a different clearo/tank - and sometimes it's a sign that it is time to change coils/wicks, since too much ejuice is getting by the coil into the airflow system of the tank.
