Personally, I think they should be able to do whatever they want. Their job is highly stressful and cigarrettes are a lot better than plenty of other things they could be using to take a load off (drugs, alcohol, anti depressants, and more) so yeah, cigs suck, but let them live!
There have been plenty of members of EXO caught with cigarettes but people were shocked when the lead vocal, Kyungsoo, was seen with a pack. Kai even apologized when his photo was taken with one.
Taemin smokes vaporizers.
Top is a known smoker and, unlike many idols, doesn't hide it from anyone.
Daehyun outted himself when he posted this selfie with a pack of cigs in his pocket. Fans immdiately asked him to stop in order to protect his voice/health.
It's safe to say that more than half of Super Junior smoke.
Its not really suprising that a man of his age in Korea smokes, but I wonder how that affects his dancing!
Jaejoong is also not shy about his smoking habits. He even poses with cigs in magazine shoots!
Donghae has been seen smoking on multiple occasions.
Like TOP, GD doesn't try to hide his smoking habits either.
10. Kang Daniel
Recently people were shocked to see Daniel with two packs of cigs in his pocket.
Surprise! Another SUJU member haha
Yunho also has been seen smoking on and off
13. Sehun (and Tao)
Sehun got in a lot of trouble for this when it came out, but based on more recent photos, he's kept it up.
