Bruno Mars Invests in Electronic Cigarette Company

It seems Bruno Mars is trying his best to kick a bad habit. The 27-year-old singer is investing in NJOY, an electronic cigarette company, to help him quit smoking.

The "Locked Out of Heaven" star began using the product on Mother's Day as a gift to his mother, Bernadette Hernandez. "Day 1 E-Cig, gotta do it! This one's for you mom," he tweeted. Sadly, Bruno's mother passed away on Saturday, but it seems he's still keeping his promise of living tobacco-free. "I've been using NJOY Kings instead of cigarettes these days and I'm sticking to it," Bruno said in a press release. "I believe in the product and the company's mission."

NJOY electronic cigarettes are made to look and feel like the real thing. While many, like Bruno, have turned to this product for help to quit smoking, the World Health Organization said it does not consider the product to be a legitimate therapy for smokers. "WHO has no scientific evidence to confirm the product's safety and efficacy," stated Assistant Director-General of WHO's Noncommunicable Diseases and Mental Health Cluster, Dr Ala Alwan.

There may be no scientific evidence, but Bruno believes in it and will continue to endorse the brand.
