See my two posts on page 6 of this thread. In addition,

And here's another summary
Here's What We Know So Far About How Marijuana Affects Health
Again, any drug can legitimately be used for medical reasons. But I know from personal experience that marijuana is not harmless.
As far as the first article, it didn't really talk much about
what the "marijuana-related health problems" were. Im assuming it's in that one sentence that says:
The study noted an association between marijuana use and serious health problems, including sudden cardiac death, myocardial infarction and stroke.
And
Risks posed to youth include lung problems, memory impairment, risk of heavy dependence, mental health problems and poor cognitive performance, according to the U.N. report.
Anyway, it's important to mark a difference between
marijuana-related and related to
smoking marijuana. A good extract does not pose the same health risks related to smoking or vaporizing. I checked the abstract from the study which noted that it was focused on the inhalation of marijuana, so i'll assume that the potential risks mentioned are only related to the smoking and possibly vaping of cannabis. We cannot say "marijuana does this" when it's specifically and only the smoking of marijuana that does "this".
In the case of teenagers, I certainly agree that they shouldn't be using it so much or at all because of their developing brain; teenagers shouldn't be drinking a lot either.
As far as the second article:
And even the immediate short-term effects of the marijuana, such as impaired thinking and coordination, can have consequences, including difficulty in learning in school and an increased risk of car accidents, the review said.
It's kinda a no-brainer (hur hur) that using MJ or any other mind-altering substance in class or while driving is going to impair your performance.
"So you're saying that something that causes me to lose focus (in moderate to high doses) is going to make it more difficult to drive or remember things that the teacher is saying in class? Get outta town!"
Regular marijuana smokers are also more likely than nonsmokers to have symptoms of chronic bronchitis, such as daily cough and phlegm production.
So, people who inhale smoke regularly are more likely to have symptoms of chronic bronchitis than people who dont inhale smoke on a daily basis? Who'da thunk? I thought it was only tobacco smoke that did that, not like, you know, anything else with irritants in it...
As far as the "few more highlights from the review":
Point one, I disagree with. You're addicted when you have next to no control over something and you don't do it just because you enjoy it. If someone doesn't have any control over their cannabis consumption, I think there's an issue with their own self-control. Sure, you can definitely be habituated to using it if you do it on a daily or semi-daily basis, and it might be hard not to partake (because, you know, when you have near-instant enjoyment in the form of just lighting up, it could be difficult to not do it if you dont know how to enjoy yourself otherwise). That =/= addiction by any means, nor is it
dependence, which is an equally strong word, IMO.
Point two, I agree with. Teenagers, with their developing brains, should avoid moderate to heavy alteration of brain functions. "Getting high" usually involves moderate to heavy consumption at a given time, so of course, conclusions made here probably do not take light consumption into consideration. Some people do like to have just a bit to help relax but not get "high".
Points three, four, and six have their own caveats built in, which speaks for itself, and point five is a no-brainer that applies to any substance that alters focus and reaction time.
Please note, my sarcasm isn't directed toward you, sunrise, but the articles. Im not arguing that cannabis is harmless, there are potential risks for certain people and based on certain forms and regularity of partaking. What I am trying to do is point out that it is not some inherently dangerous substance either. It can be medicinal and it can be used safely in a recreational context.
