Re: blue mist...
I had 250g of the blueberry vaporub from when they first released it. It was an amazing flavor but every session after the first 3 or so seemed to always be too hard to manage. Either burns or no smoke at all. I didn't leave it out or anything. I assume it might be a hard flavor to keep properly moisturized/acclimated. I haven't bought any since because I have a feeling it would happen again. My favorite SB flavor is Safari Melon Dew by far though, so I'm not worried about it.
