Marijuana users suffer from the lungs more than regular smokers, researchers reported in a recent study. In fact, marijuana can cause more lung damage than 2.5 to five cigarettes. The researchers said that cannabis, the plant source of marijuana, was associated with a dose-related impairment of the large airways, causing airflow obstruction and hyperinflation. But unlike cigarette smoking, cannabis was rarely associated with macroscopic emphysema.

Cannabis is the most widely used illegal drug worldwide. Long-term use of marijuana is known to cause chronic bronchitis and airflow obstruction, but the prevalence of macroscopic emphysema, the dose-response, and the dose equivalence of cannabis with tobacco had not been determined yet. In a study were investigated 339 adults, ages 18 to 70. They were recruited from the Wellington region and putted into four groups: cannabis only (75 people), tobacco only (92 people), combined cannabis and tobacco (91), and non-smokers of either substance (81).

More tar, apart from the long-term effects it has on the brain. Many people in hospital with mental health issues have been on cannabis. I sure wouldn't want to become a patient!

kevin's gonna be pissed

jason be making all these topics

^Lawl, who' Jason?

Yeah OP is just asking to be schooled on this.

^^Marijuana use doesn't damage the brain? LMFAO!!! Can't be serious ... Marijuana is PROVEN to destroy brian cells. Hence why all the big potheads in my school have 0.8 GPA's and have trouble remembering things. If Marijuana is so good for you, why is it illegal? I'm sure the Government would look at the articles you just posted and legalize it right away if there were 0 reported deaths from Marijuana and that it doesn't cause cancer or even brain damage and it's healthy!!! If Marijuana is so good, what was the big deal about Paris Hilton and Michael Phelps smoking Mari J? Why did it get so much attention (Magazine, Articles, Newspapers) I thought it's healthy for you? And since cigarettes are so bad, much more worse than weed, all the big name celebrities should be on the cover of a magazine with big letterings, "CIGARETTE SMOKER" right ?? Haha ... hey seriously, why is Weed illegal then? Doesn't cause death or brain damage ... it doesn't mess you up psycologically at all. It's healthy for you and gets you high. Hahahaha ... please, I laughed after reading that link.

You want links?

Omit that anonymous blog and you're all good.

drinksmokef*ck still got more reliable news sources than you.

goddamn i don't even smoke weed, but goddamn

you must really trust the government

lol, oh cause because its illegal so it must be horrible for you, guess what shit stain, so was alcohol and women's right to vote, you also realize that a ton of college students blaze right? and im pretty sure they are a lot smarter than you

also, who the f*ck said anything about it being healthy? oh yeah no one, you gaping ass queer

^ LOLLLLLLL kevin's post is full of hate. HAHAHAHAHAHA.

i know a ton of students blaze, it's their choice but if your a consistent pothead who blaze everyday, then it's terrible because it can kill your brain cells, and who would want that especially if your in college? you don't want to experience any psycological problems do you ... at least cigarettes don't cause those type of problems. and can't guarantee health issues like lung cancer although the possibilities are high. blazing is a guarantee you will experience some sort of a side-effect whether it may be decrease in reaction time, not remembering things, etc. i'm not a supporter of either one, marijuana or cigarettes, but from what I researched and from what I know, marijuana is worse. and maybe click on the links I actually posted, they might enlighten you.

Perhaps the potheads in your school are really stupid, or perhaps you just group a bunch of punk kids together and automatically assume they're potheads, and forget all about the other marijuana users who are disguised as cheerleaders, the pastor's daughter, and football players. Well, actually, the latter is quite rare, since UIL comp. requires drug tests, but there are discrepencies.

Not tryna boast or anything, see, but I'm a daily user of marijuana, and have been for quite some time now, and I maintain a 4.0+ GPA through programs like AP courses.

Perhaps, you should reword your sentence, because no, we cannot explain how all the potheads have 0.8 GPAs. (By the way, 0.8, that sounds absurd. Did you make it up?)

uh. no I did not make it up .. a lot of the potheads in my school are legit dumbasses .. in fact, one dropped out a month after school started. and ok I'm not going to go against you for being a daily user of marijuana but always keep in mind that what your using is ILLEGAL and once you get caught it with it, your going to go through some serious shit ... moving onto cigs, they're obviously not good either but according to researches and studies, you don't experience any instant effects .. do you? i mean maybe coughing out blood but that's rare. for weed, whole new different story and you have to agree with me on that one .. cigs = bad but good in a way that it KO's my stress when you feel like your going to explode like a volcano, and police won't do shit when they see you smoking a bogie on the sidewalks unless you look 11

Wow, funny. I just came from a wedding where the 10 surgeons in my family were discussing marijuana, how to obtain it legally in CA (aka go to my mom's cousin in LA and tell her you have cancer), and the different drugs MJ was taking before he died.

Tbh, the long term effects of weed on brain cells is so minimal that it really doesn't make a difference at all. :)

Yeah, at least cigarettes don't cause brain damage, because I rather take death.

Are you saying smoking cigarettes won't guarantee a side-effect as time increases?

I don't need your links, you as an idiot enlightens me thoroughly.

So all in all, your answer is 'no'. You did not make up the 0.8 GPA? How do you explain dropouts who do not use marijuana? What else are you going to blame it on? Daddy issues? Or just contact high?

"and ok I'm not going to go against you", Okay, I don't need your disclaimer. I don't want you on my side.

My teacher is around 70 years old, has been a cigarette smoker since 20, and he's in fine shape today. No lung problems, no heart problems, greatly, no cancer! Same with my maternal grandmother and my father. Yes, the risks are high but DOES NOT guarantee health problems. Even less of a "no guarantee" if your not a chain smoker. And like I said, you don't experience any instant effects like you do when smoking weed. Cigarettes just calm you down and relieves stress.

Still about the GPA ... sigh

your using an illegal substance. end of story. if it's medical marijuana and you got it prescribed, okay. otherwise, it's not okay. just don't be like the idiots here who carry weed in their pockets in town, you never know if it's going to slip out and next thing you know, a police car is right behind you. FCUKED. bye.

When compared to a healthy, non-smoker, how would your 70-year-old teacher stand?

*^x2 lol wtf is wrong with you

Yes, I'm still bamboozled about the GPA, it's awfully low to be considered true. So, when I can find a fault in what you have to say, which is plenty, then I can convince myself that all you can spit out are fallacies that you believe.

Are you a pothead? Cuz you're a 'legit dumbass' too.
