Why marijuana sometimes is shown to cause damage

    As new studies come out I have noticed that they are starting to link smoking (anything) to causing possibly significant brain damage due to oxygen deprivation. Maybe the studies on cannabis are flawed due to the fact that what they are sometimes looking at is actually brain damage caused by how the user ingested thc. This is why Vaping is known to have a clear (free of oxygen deprivation/"head-rush") effects high, but sometimes the user craves the other component of cannabis (CBD) which is not activated by vape smoking. These people use safer methods (Single hit sessions, vapes,edibles) and maintain a healthy brain. These people are lacking the brain injury and have more energy, which is why the studies where self proclaimed smokers who tend to use healthy methods volunteer themselves, the studies normally show no damage to the brain of the study participants.

    At the same time the studies they do are on groups who use oxygen depriving smoke techniques such as having multi-hit (damaging) sessions are shown to have damage to the brain. The ones who do that are highschool stoners, joint/blunt users, and people who use multiple hit pipes often, and sadly this makes up most of the pot-smoking community. So my point is that method of consumption and probably amount of consumption for one-hit users is what I believe determines whether cannabis harms the brain of the user or not, this in my opinion explains why the studies have had very mixed results.

    The study that showed a link between brain damage and smoking cannabis was disproved due to error in method. They were suffocating the test subjects, which of course leaves to brain damage. Currently there isn't anything showing legitimately and conclusively that smoking cannabis leads to brain damage, that I know of. Quite the opposite actually, marijuana has been found to have distinct neuroprotective properties and could possibly encourage neurogenesis in the hippocampus and other parts of the brain.

    You do say these studies you are referencing are 'new', though. Do you mind providing links?

    What studies? Smells like some bullshit to me.

    Only study I read that discussed brain damage was that one with the monkeys getting suffocated by gas masks and pure weed smoke.

    Depriving the brain from oxygen for minutes will kill braincells. So unless you hold your hits for 3-5 minutes everyday, you're fine.

    Yea, thats the only study i´ve heard of where it was "proven" to show that it caused braincell damage, but they where suffocating the monkeys, so it was no surprise.

    there is nothing in this world that is completely benign. brain cells die ALL the time and are constantly being replaced. whats important are the connections between the synapses which is how memories and thought stored and travel and those are destroyed by a persons disuse.

    of course smoking has some ill-effects. nothing in this world is free, you have to give up something to get something of value. its a rule of nature. you just get more bang for your buck with marijuana so to speak. lol

    Now you all have a choice!

    You all can go on, cluelessly guessing and supposing :confused: , or you can read some of those and educate yourself! And don't give me the "I don't understand the big words" excuse! Even the average high school student can understand the news articles- and we are all over 18 here! :p

    We have got a lot of MMJ related stuff coming up this fall, and it really helps to know what you are talking about when you are trying to change people's minds! Once you've learned the medical facts, it is easy to demolish most prohibitionist arguments! And with my list- you have the medical studies to back yourself up! (Read the news articles, and then give the prohibitionist the actual study to wade through, while you look like a genius, spouting the facts from the news! :D lol)
