A boy has become a mental patient, and he continues to misbehave with everyone. It's all because of smoking, because he used to be very good. Sometimes I don't believe it's the same guy, and it's all because of smoking

I know of someone who has been in rehab for months now and isn't coming out anytime soon because of smoking harmful substances. I do always feel for these people when they suffer the consequences of smoking, but then if you ask most people, they will tell you they started smoking because they were depressed, stressed, or because of peer pressure.
