Doughdreads, I think you need to do some serious research before you jump into the vaping market as an investment. Please make sure you are fully aware of the impending FDA deeming regs and realize that the only viability of the vaping phenomena is as a short term investment until the regs are published and accepted. This could be a booming market, or a devastating investment depending on this one issue. Please do the proper research, and after you do you will be able to answer your own questions.
If you are looking for just a short term investment, you might want to consider approaching a reputable, established vaping business as a partner rather than an add of a public company to your investment portfolio. For now, short term profit should be your goal.
