Good thinking batman.

37, It would actually be kinda hard to extract DNA from a cigarette butt because how hot it burned or something like that. I think you might just get a partial fingerprint. I think they had an episode of Law and Order: SVU about it. But the tag idea is much better.

If there's one thing I've learned from 30+ seasons of various Law and Order shows it's that cigarette butts will hold your DNA. That's why I use cigarette holders when I'm planning on throwing them out the car window and burning the driver next to me.

64, Doesn't get hot? Yes it does. Mostly when you get down to the last fourth of the cigarette.

Did some additional reading, if they're a dry smoker, meaning they don't let it really let it get wet, then it's harder. Just because it's in your mouth, that doesn't mean it's covered in saliva.

When you're sitting in your car, strapped and expecting no burning things thrown behind your back, then it might take you a little while to get away from it and I'd like to see you reacting fast enough to avoid burnings...

whats worse is people defending their right to smoke when all it is is a bad habit that used to be accepted. seriously how dumb do you have to be to smoke a bunch of chemicals and herbs that you know is dangerous and then bitch at those who point out your stupidity. before anyone mentions drinking alcohol as a comparable habit just remember i cannot drink anywhere nor can i get five mina extra brwak

Do you know just how many things are unhealthy for yourself or those around you? Forget smoking and drinking, how about heavily processed food, the gases emitted from cars, pollution from factories etc. People don't necessarily defend smoking itself as smokers are very aware of what they're doing to themselves, rather they defend their right to do so. Just as people who die young from too much fast food do.

Don't forget that smoking is a legal government subsidized addiction. And that the companies behind it are very predatory in their tactics. More so than drug dealers, for the most part, because being a legal product they can get away with a lot more.

hmm lets see i dont drive so dont contribute to the pollutiom problem and if i do happen to eat fast food its a problem that only affects me. no one gets passive fat. at least fast food offers some sort of nourishment cars are transport are a neccesary evil and alcohol can have health benefits what exactly are the benefits of smoking. and dont site realxation and destressing because thats a placebo at best.

Why is your logic that if you don't do it, it's okay? You don't smoke yet your chastising that. Anyway smoking lowers risk for parkinsons and other neurological diseases, it can reduce schizophrenia,and the risk of alzheimers and dementia. And for obvious reasons wards off obesity since its an appetite suppressant. I'm not defending smoking and I'd never advocate that anyone start, but once you're hooked you're an addict to the nicotine and that sucks. I also find the anti–smoking mentality that a lot of Americans seem to have laughable. Honestly why care what someone does to their body? If it's being blown in your face tell the smoker. The smoker in this post is an asshole but could have just as easily been a drunk driver or road–rager or even someone tired that caused harm. Sorry for the essay.

i dont know where you got your facts from but i would recheck them. even if it is true i woild.much rather have dementia than lung cancer or emphazema.

I'm not sure about schizophrenia, but there have been numerous studies showing it decreases the risk of Alzheimer's and Parkinsons. Both diseases are caused by decreased dopamine in the brain, and smoking increases dopamine levels. Although you get a similar effect from drinking 3 cups of coffee a day, and I would much rather drink coffee than smoke cigarettes.

Then you also shouldn't be allowed to drive or purchase anything that was made in a factory.

Yes, because prohibition and making things illegal works SO WELL!

But then think about the people who would be out of work!!!!! Who cares how clean the world is when every single person can't have a job!!!!! Just think about the loss of the jobs!!!!! (I was totally kidding).
