Humans - 

With Humans, Smoking may lead to chest pain, heart attack, heart failure, arrhythmias, or death. But a common thing that happens is lung cancer. Which will also shorten a Human's life span, and give uncontrollable pain. Although, a Human's DETERMINATION will not be affected in any way by it, their SOUL can darken, crack, or even break parts off, which is unbelievably painful.

Monsters - 

When a Monster smokes, their Magic can go off balance, even leading them to hurt others. It will often lead the holder's magic to attack the ones they love and care about. Smoking, much like Humans, will cause a Monster's SOUL to crack, darken, and/or break. Causing unbearable pain. It usually takes about 2-3 months of smoking for any of these affects to start kicking in.

Mythicals - 

UNKNOWN.

Even though we have not had any Mythical volunteers to smoke. We do believe that they turn more and more aggressive over the time that they smoke. And after a long time, they may start to attack friends, family, strangers, and others.
