Cigarettes and second hand cigarette smoke are dangerous.

Smoking can damage our body, For Example, your lungs, your brain, and your heart. The poisonous chemicals in a cigarette can cause death. Think about this, if you smoke you won't be able to run fast or jump as high if you can't breathe properly.

The City Council and General Assembly can nurture that choice by requiring all bars and restaurants to determine their own smoking policies. Smoking-allowed establishments can then choose whether to be all-smoking or to have separate smoking and nonsmoking sections. To help consumers identify which establishments cater to their preferences, bars and restaurants could be required to post their smoking policies at their entrances, and they could be penalized for violating them.
There are surely other associated risks specific to your own situation (e.g. if you smoked in the house, I would factor in risk of fire) . Don't forget to try to take these into account.

The Wednesday of National Non-Smoking Week is termed Weedless Wednesday. Smokers are urged to refrain from smoking on this day. The intention is to kickstart the process of quitting smoking as well as gaining media coverage.

Passive smoking is the act of breathing in secondhand smoke.

Tobacco smoke contains over 400 chemicals, and over 60 are known or suspected to be carcinogenic (cancer-causing). A controversial study published in the British Medical Journal appears to show that in non-smokers regularly exposed to smoke via their spouses were not at significant risk of cancer or heart disease.

According to Cancer Research UK, passive smokers are 20 to 30 per cent more likely to develop lung cancer than people not exposed to smoke, with several hundred deaths occurring as a direct result in the UK each year.

Tobacco contains nicotine, a powerful neurotoxin that is particularly harmful to insects. A lethal dose of nicotine is contained in as little as one half of a cigar or three cigarettes; however, only a small fraction of the nicotine contained in these products is actually released into the smoke, and most clinically significant cases of nicotine poisoning are the result of concentrated forms of the compound used as insecticides. Tobacco leaves are often smoked (see tobacco smoking) in the form of a cigar or cigarette, or in a smoking pipe, or in a water pipe or a hookah.

I might be trying to et a job in a month or two and i want to know if the drug tests you are required to take can detect if you smoked marijuana? If i smoked just yesterday how long does it take till drug tests cannot detect that you used marijuana?

It varies but it doesn't really depend on your metabolism. It also depends on how much is in your system...If you been smoking every day for over month it will probably take you 8 weeks to get weed out your system. The more you sweat, pee, defecate (aka excretion), the less will be in your system. There for meaning prune juice, de-tox formulas, cranberry juice, teas, running with multiple layers are all great ways for getting marijuana's THC out of your system. 4 weeks should be plenty if you drink the above mentioned liquids, drink an excessive amount of water each day, and promote a lot of sweating. That's blood and urine tests. A follicle test though is tougher....shave your head that's your only real way out of that. Or most costly but simplest of all...buy a whizinator and find a clean friend.
