I don't vape cinnamon "candy" flavors, but I do regularly vape cinnamon bun and cinnamon danish flavors from several vendors, and have had no problems so far. I have been vaping for around 4 years so far.
If you do not already have one, I would suggest getting a glass tank for your battery before trying a cinnamon vape. When my daughter and I moved up from cigalikes with cartos to Evods with tanks (clearomisers) a couple of years ago, I also made sure to order a Kanger Protank 2 Mini for each of us. My daughter found out why I made sure to have glass tanks for us a week later, when she loaded some Wild Cherry eliquid into her plastic Evod tank for the drive home from work. By the time she got home - about 20 minutes later - she had Wild Cherry eliquid all over the front of the car. The eliquid had melted the plastic tank. My daughter had not noticed when she ordered the Wild Cherry that it was listed on the vendor's site as a "tank cracker".
Have fun, and don't forget to shake your eliquid before filling or topping off your tank.
