See with me, I dislike smoking a ton because of what I've seen it do to people. I'm fine with them smoking if it makes them happy, but when it doesn't is what hurts me so deeply inside. Smoking is a horrid habit in the first place, inhaling toxins that shouldn't be near the body in the first place, then including that you do it constantly. I just don't see the appeal in it. I've seen the effects it has on people physically, and it's really painful to watch, but the mental effects are overwhelmingly destructive. I just can't stand to see it anymore.
Smoking should be stopped, along with all other substance abuse. But smoking has many physiological effects on peoples brains when it is activated. It blocks some of the passages and emotions that enter the human brain, making peoples thinking irrational and usually worse. People lose self control and emotions and when they stop it, the effects are even worse. I've seen people drive themselves so deeply into depression when they smoke, that they can't get out. It's a horrible thing to see, and should be stopped truthfully.
Now you can say this about all drugs and I believe most drugs should be stopped in general. Because these PDA things are right, smoking is bad, and smoking should end. The withdraws are unbearable.
