So i have been doing a crazy amount of research, but the one thing i can't figure out for sure, is how the solution works. Here's what i do know, followed by what i need to know. I know if i buy an e-cigar, it will come with a few flavors, and once I vape them, I will need more. So what do i do next? Can I pour different flavours into the capsule that it came with? Do i need to wash it out first? Do i need a fresh capsule thing to put fresh solution in? Are there differences in the juice you buy for cigarettes and cigars? Someone please respond, cause as simple as this must be, I'm not quite where i understand it yet.
