^ Faial bhai, if your drinking coffee, the person standing next to you does not die.
if your smoking, the effects of smoking, second hand-smoke, are worse for that person then the smoker himself. I spent a lot of time on this topic during the last semester at school and i'll post some of the facts.
Five people in United States alone die every six minutes because of a ciggerate related disease.
Two thirds of smoke from a cigarette is not inhaled by the smoker, but enters the air around the smoker.
Second-hand smoke has at least twice the nicotine and tar as the smoke inhaled by the smoker; That smoke which is inhaled by the non-smokers contains more than 4,000 substances, of which more than 40 are known to cause cancer. Second hand smoke, like radioactive radon gas, has been classified as a Class A carcinogen by the Enviornmental Protection Agency.
So forget the fact that your smoking and killing urself, ur killing the people around you.
Many Muslims regard smoking as MAKROOH (disliked) by the Shariah but not HARAAM ( forbidden). Whenever advice is given in this regard they choose to ignore it. Though people know the evil effects of smoking, it seems that Shaytaan and their nafs wants them to continue wasting their money and cause harm to their bodies and HEALTH.
SUICIDE BY SMOKING
Most Muslims are aware of and try to avoid the major sins in Islam - murder, suicide, adultery, alcohol, gambling, usury, etc. Muslims are forbidden to harm themselves or others. Yet millions of Muslims all over the world are doing just that - harming, even killing themselves and their families. Islamic scholars have historically had mixed views on the subject, and the actions of these Muslims have not been unanimously forbidden or even discouraged.
The danger is tobacco use - cigarette and cigar smoking, chew, etc. The mixed views on the subject came about because cigarettes are a more recent invention and did not exist at the time of the revelation of the Qur'an in the 7th century A.D. Therefore, one cannot find a verse of Qur'an or words of the Prophet Muhammad (peace be upon him) saying clearly that "Cigarettee smoking is forbidden." However, there are many instances where the Qur'an gives us general guidelines, and calls upon us to use our reason and intelligence, and seek guidance from Allah about what is right and wrong. In the Qur'an, Allah says, “...he [the Prophet] commands them what is just, and forbids them what is evil; he allows them as lawful what is good, and prohibits them from what is bad..." (Surah al-Ar’af 7:157). So what are the evils of tobacco use, for your health and for your deen (religion)?
Danger to your health
Allah says, "...make not your own hands contribute to your destruction..." (Surah al-Baqarah 2:195); "...nor kill yourselves..." (Surah al-Nisaa 4:29). It is universally understood that cigarette smoking causes a number of health problems that often ultimately result in death. Men who smoke contract lung cancer at 22 times the rate of non-smokers. Smokers are also highly at risk for heart disease, emphysema, oral cancer, stroke, etc. There are hundreds of poisonous and toxic ingredients in the cigarette itself that the smoker inhales straight into the lungs. In an authentic hadith, the Prophet Muhammad (peace be upon him) said that "Whomsoever drinks poison, thereby killing himself, will sip this poison forever and ever in the fire of Jahannum (Hell)." Over 3 million people worldwide die from smoking-related causes each year.
Danger to your family's health
In the Qur'an, Allah says: "Those who annoy believing men and women undeservedly bear on themselves a glaring sin" (Surat al-Ahzaab 33:58). And the Prophet (peace be upon him) said that "there should be neither harming, nor reciprocating harm.” In another hadith, the Prophet (peace be upon him) said: "Anyone who believes in Allah and the Last Day should not hurt his neighbor." Those around the smoker inhale what is known as "second-hand smoke" - the unfiltered, poisonous waste that goes in the air around the smoker. There are over 4,000 chemicals in cigarette smoke, over 40 of which are known to cause cancer. Second-hand smoke causes or aggravates asthma, bronchitis, and other respiratory problems, especially in children.
Addictive
The addiction to tobacco is a physical response that often interferes with one's life and worship
(I personaly know someone who can not fast, why? because he can't go on more then an hour w/o a ciggerate and chewing tobbaco)
Waste of Money
Allah says, "...But spend not wastefully (your wealth) in the manner of a spendthrift. Verily spendthrifts are brothers of the devils...” {Surah al-Israa’ 17:26-27} And in an authentic hadith the Prophet (peace be upon him) said that: "Allah hates for you three things: gossiping, begging, and wasting money."
oh and btw... coffee IS a drug. Coffee is classified as a drug. :)
