The believer can eat food offered to idols?

It believer who thinks not, but if you read a little book I Corítios 10:23-33, and you will see that in the times of Apostle Paul had this discussion there were some brothers who forbade other brothers of feeding on food sacrificed to idols, still ban this practice continues to the point that "some pastors" to prohibit its followers from eating such food, so far as to say that if any believer to eat will be subject to sin, sickness and even curses.
Paul demystifies the subject for him as Jesus taught what defiles a man is what comes from the mouth of man and that comes in the form of food, Paul says that we still eat everything without asking whether it is sacrificed, "because the Lord is the earth and its fullness." If by chance, a "weaker brother" is offended, so not to offend his brother, then do not eat to avoid weakening his weak brother in the faith.
Food offered to idols have no power against the believer in Christ because in Christ there is no enchantment. Stop asking whether or not offered, do as Paul, as you can eat.

The believer can smoke?

Sure, provided you are willing to buy a lung cancer, otherwise it is best not to smoke. For me (personally) have never had any temptation to smoke cigarettes, smoking is also something that you are harmed without even take a hit, you just live or live with a smoker.
Usually people who smoke are children of parents who both smoked and smoke "accidentally" got used or were conditioned to smoking addiction. Others are products of the films, which feature heroes with a cigarette in his mouth as if it were "full" of beauty and social status, this only proves that the media can be addictive and lead to misunderstanding. Smoking should be prohibited in Brazil, thousands of people die every year as a result of smoking, it has to end.
The addiction to cigarettes is one of the worst there has smokers who stop buying milk and bread down a cigarette, and I know many others who want to quit smoking and failed to find a way out, because once a drug addict is one that persists for long time. Have become Christians and spend several years fighting nicotine is difficult to stop more willpower and help from relatives is crucial at this time.
Finally, the believer can want no smoking in the Bible about this recommendation, there is even some old pictures of the early Christians in Brazil who smoke cigars, but they were unaware of the evils of nicotine and other drugs present in tobacco.
Now some advice for you that you never smoked: Do not be silly.
And now a smoking advice to you: Do not be silly. Stop it. Pray and ask for prayer, and if necessary seek medical treatment.
Cherish your health is important.

A hug!
