Yes it is safe. Crown 7 is an electric ciggy that uses nicotine cartridges and water to create the “smoke”. Hmm sounds like a shisha to me. Anyway, this is created to prevent 2nd hand smoke from killing non-smokers and to reinstall the glory of puffing for the smokers without risking the lives around them. Cool, eh? How thoughtful. Crown 7 is also available in cigar formats and pipes as well.
However, this does not come cheaply at $100 for the cigarette, recharger, two lithium batteries, two filters, and two cartridges. Each additional cartridges costs $10 bucks a pop.
They should make the charger USB friendly at least, pfft.
