Almost a year.
I've been through phases. My first ADV was MBV Butterscotch, but I vaped it so long that it lost all flavor.
Boba's Bounty was the next ADV, and still is.
Heather's Heavenly Vapes Purity NETS were my next ADVs, but, like I said, I go through phases. Right now it's fruits. So I've relegated my tobaccos to my Volts and my Smok epipe mod using 3 ml carto tanks.
Now, it's all about Vapor Chef. Honey Pearry and Black Pompom are my current ADVs. Heaven in a bottle. I'm ready to re-try Bloody Mango again. Smells delicious.
Buddy of mine won over $400 of The Standard and Jameson's ejuice, but honestly, after smelling and sampling a few, I don't understand how they're more "premium" than my premium vendors. That opinion could very well change after time, however.
