I was wondering if a dirty connection from the battery to the atty affect the taste and TH. Recently, i've been cursing my 30mg juice for what I thought was giving me a very harsh and strong hit. Just this morning, I took a hit of one of my eGos, with a lower nic level and I got a similar experience. I then just took a napkin and cleaned the connection end of the ego battery, took another hit, and it seems to have went away. The atty was connected overnight. I'm afraid to drip some of the tainted mixes from my 30mg juice because it's a wack experience. Can anybody identify with this?
