Should Smoking be banned?

Def the answer would be a”Yes” if u ask me considering the health hazards caused by the nicotine. Also it’s so bad for the people around get health problem (passive smokers). This topic came to my mind just because most guys in my class smoke. Godddd just cant tolerate when ppl smoke and enter in an Air Conditioned room.
Smoking.uhhh…Disgusting.Donno y people smoke. This actually gets the thought y don’t we actually ban smoking. Y does the government not charge or fine when one smokes (when they have starting a fine for the people who don’t were their helmet). Smoking contains Nicotine, which is not good for health, and then people still get addicted to it! Health hazards due to Tobacco
Smoking restrictions and bans on sales to youth
Restrictions on smoking in public places (for example, in restaurants, public transport, and the workplace) reduce the opportunities to smoke. There is considerable evidence that such restrictions reduce both the prevalence of smoking and the average tobacco consumption of smokers. They also reduce the impact of environmental tobacco smoke on non-smokers. But this will work only where effectively enforced, bans on tobacco sales to youth appear to reduce the prevalence of smoking among young people.

What’s the use of the Non-Smoking boards in most places, but no one really following it.atleast to the extend I know one is not supposed to smoke in a manufacturing unit and what do I c the quality head smoking just outside his cabin.wowwwwww
Should it be banned only in some areas like a hospital? (I mean effectively)
Even school children outside school smoke, now that’s where we seriously have to think (may be it’s a show off for them)
Can’t we really do anything about it?
How much Profit do we earn from a tobacco company or a cigarettes/cigar company? And the best part is: Cigarette packet warning signs. They have been implemented as an effort to enhance the public's knowledge about the dangers of smoking. In general they try to emphasize the same messages?.

On the contrary one would say that Tobacco companies contribute in a lot of way. In terms of manufacturing, agriculture, and employment. But we still need to remember they def do not contribute to out health sectors. But they have a major impact on the economic growth of our country. Thus we need to c as how much profit we earn from these companies, and what would be the impact if we decide to terminate these companies and may be we could invest it in a better way which would not be health hazardous.

Wat say?
