I just got the Cloud 9 Starter Kit from a smoke shop near my apartment, and am a bit confused. It came with "prefilled cartridges" that don't seem to have liquid, but something solid looking in the bottom. It's supposedly "Menthol high" but it does not really taste like anything at all, and I don't think I'm getting much nicotine out of it. Am I doing something wrong? Are these cartridges bad? Thanks..
