I'm trying to get my significant other interested in vaping, but when he vapes his PG "Wensten" he says his lips burn and feel numb. He tried some VG Boba's Bounty and said his lips didn't burn, but he just didn't care for it (never heard of anyone who didn't like Boba's Bounty). Nic level is 24 mg on both. Has anyone else had the sensation of burning lips or numbness when vaping PG? Could the nic level be too high?
