The answer is that they do, but not as much as other electronic cigarettes.

The Blu Cig electronic cigarette has a lot going for it: a solid design, good battery life and an excellent cartridge system. However, one of the biggest complaints about Blu Cigs is that they smell.

The main reason that Blu Cigs smell is because of the propylene glycol (PG) used in their cartridges. PG is a base ingredient in many food products, including soda and ice cream. It gives them a sweet taste and helps them produce vapor when heated by an e-cigarette battery.

Some users have complained about the smell of PG, saying it can make them feel sick or even give them headaches when vaping for long periods of time. However, there are also some people who enjoy vaping with PG because it produces more flavor and increases vapor production when compared to other e-juices like vegetable glycerin (VG).
