Can Marijuana kill you? Can anyone Scientifically PROVE their answer?

First of all let me say: I have a Marijuana Card. I do use Medical Marijuana. I 100% support federal legalization of Marijuana.
With that said, this is from my experience:

Literally every person I've ever heard say Marijuana is perfectly safe, it is impossible to die from it has been just a regular person or a stoner! I've never heard a Doctor, Nurse, Pharmacist, or Scientist say this! In other words, 100% of the people I've heard this from don't truly know what they are talking about!
I have a Medical Marijuana Card in FL. When I went to the Dr to get my card, she said, "She doesn't know of any 'DOCUMENTED CASES' of people dying from Marijuana itself. But, people can and do die from smoke inhalation, auto accidents, because they drove after smoking weed, falling down and hitting their head on the ground, picking fights with people in a bar and other things.
The Marijuana plant itself didn't kill them, but, the other affects that the weed caused did kill them.
Also, I've never heard an Historian say that nobody ever in human history has ever died from weed. Humans have been around for over 7 Million years! The oldest human remains ever found were over 7 Million years old. The English language was invented about 1,000 years ago. People didn't always keep accurate historic records, especially not about Marijuana. If someone does find historical documents about someone dying from Marijuana
1 Million years ago, it will not be written in English. It might not be written in any language that exists today at all!
We will never know if someone died from weed 1 Million years ago.
Before humans came Dinosaurs and Thousands of other extinct animals. Did any Dinosaurs ever die from eating Marijuana? We will never know!
Weed has been legal in Amsterdam and several other countries for a long time. Until the 1930s, it was also legal in the US.
We will also never know if at least ONE person died back in the 1800s or before that.
I asked the Doctor how much weed someone would have to use, before it would be fatal. She said, it'd be a lot! Like, smoking over 100 joints, one right after the other! Or eat tons of Marijuana cookies.
But, if you smoked 100 joints in a row, that's stupid! You'd die of Lung cancer before the weed itself killed you.
I say again: I got my information from a Doctor! I also have a FL, Medical Marijuana Card. I do use Marijuana occasionally, for medical reasons. I also know about weed from personal experience.
99% of the people whom I've talked to about weed are NOT experts! They are know it all's, stoners, people who have friends who smoke weed and people like that, who really have no clue what they're talking about! I've only talked to ONE (1) expert on the subject. She was a Marijuana Doctor. I've also read a lot of medical information about weed and I use Medical Weed.

(My experience: I have used Marijuana over 100 times. I always get light headed, every time I use it. When I smoke it, it makes me cough, sometimes a very bad, loud cough.
It has made me vomit two different times.
I can't concentrate for more than about Two minutes.
I have no short term memory at all. I tried to read, it took me about 10 minutes to read Two paragraphs and I didn't even remember what I read after I read it!
I can't stand on one foot or walk a straight line.
However, when a friend of mine used THC drops, it didn't have any of those affects on him. In fact, as a Scientific experiment, he drove a car down some back roads, where police don't usually hang out. He did fine. He didn't drive like he was drunk. He stayed between the lines on the road.
Just don't believe everything these  "Experts" tell you! If they are not a Doctor, Nurse, Scientist, Pharmacist or something similar, they are not experts on weed or anything else! Most of them are stupid! Just like a "Barracks Attorney" (Someone in the Army who trays to give you legal advice, but, they are not an Attorney. They never went to law school. But, they only think they know everything.)
Just because you read something on Facebook, doesn't mean it's true! If you do believe everything your friends say or everything you see on the Internet, it could get you killed!!!
Just because everyone you know says something is 100% safe, doesn't make it safe! Nothing is perfectly safe! Not even breathing the air or drinking water is totally safe.

What if NASA offered you a chance to go to Mars? Would you go?

DO YOU WANT TO GO TO MARS?
A lot of people, including myself, really love outer space. But, do you really want to go there? Probably not!

If NASA called you and gave you the chance to be one of only a dozen people to go on the first trip to Mars, would you go?
It sounds cool. I have always wanted to go to outer space. That would be so awesome to spend one day in space. If, it only took a few hours to get to Mars, that would be cool to.
But, be careful what you wish for, because, you might get your wish!
On the space station, they recycle water. In other words, the water they use to flush the toilet gets filtered and cleaned. Then it goes back into a tank and the Astronauts drink that water! Then, they pee it out into the toilet, it gets filtered again, goes back into the holding tank and repeats the process over and over again! Yuck!
They lose muscle mass, because, in almost 0 gravity, you don't get to work your muscles very much. They have to exercise 2 hours a day to prevent muscle loss.
Food doesn't taste the same in space as it does on Earth.
What would you do if you can out of food or if the food you have with you spoiled or rotted and it was no longer safe to eat? The nearest grocery store is about 35,000 miles away, on Earth.
It is a very small space on a rocket, space shuttle or the ISS. It would get boring up there in those cramped quarters. If there is someone up there with you that you don't get along with, that would suck for you! It will take about 5 or 6 months to get to Mars with today's technology. You'll be on the planet for probably 6 months to a year, then a 6 month long trip back to Earth. All that time, you'd be with someone you hate!
The closest Doctor to you will be on Earth! If you get sick or injured, you are on your own. You will be able to call the Doctor on Earth and talk to him, but, he can't give you any prescription medication, stitch up a wound, put a cast on a broken bone, perform surgery or anything like that!
Mars is much smaller than Earth. That means there will be less gravity. That will have an affect on your weight, the amount of pressure and stress on your Spine, how you walk and other things. Astronauts have no stress on their spine on the International Space Station. In fact, while their in space, their spine stretches out and the Astronauts are about an inch or two taller in space. After 6 months, they come back to Earth and the Earth's gravity pulls their spine down and puts stress on it again. That causes back pain.
There are a lot of dust storms up there. The wind blows the Red, Iron Oxide all around and it will be hard to see. The wind might even blow you around as well. You will be much lighter on Mars than on Earth.
(The surface of the planet is made up of Iron Oxide, which is basically rust from iron, just like on a car. That's what gives Mars it's red color.)
You'll have to wear a space suit everywhere you go. You might get a hole in your suit, which you can't just fix with duct tape. You could also run out of Oxygen or have problems with your O2 tank. Either one of those things: a hole in your suit or problems with your Oxygen, would be life threatening.
It is very cold and dusty up there on Mars. The atmosphere doesn't stop Metiors or harmful UV Ray's, Gamma Ray's, X Ray's, and other harmful things from space as well as the Earth's atmosphere does.
If your space ship breaks down, there's no one there to fix it and no way for it to be fixed. You would never make it back home to Earth.
I am sure you'd have to sign a waiver before you went to Mars, saying you know all the risks you're taking and if anything happens to you your family can't sue!
On the bright side, you would die famous. You would always be known as one of the first people to ever land on Mars. NASA would probably name a satellite after you, your birthday might become a national holiday, people would write books and movies about you and your name would be as famous as Neil Armstrong, Galileo, Stephen Hawking and Edwin Hubble.
