Smoking is that bad?

[AngelColvin]

I am smoking for a 4 years. Decided to quit, and was searching at the internet different methods to do it. I found an article about smoking and how to quit. There was an information that cigarettes can cause an erectile dysfunction. I am wondering if someone has such problems?
Also, I am training at the gym and want to know does smoking influence on building musscle mass?

Is smoking that bad?

Yes. Yes it is.

Yes, it influences negatively on both of those. It damages your tissues, your DNA, makes it much harder for your blood to carry the nutrients needed to build muscle and heal damage.
