Cannabis Use Poses No Risk To The Brain Or Individual Intellect


iq intelligence marijuana use consumptionBy David The Expert

Delegate Ready, I was surprised to see your reply to my comment on TheWeedBlog. I’m glad that you took the time to explain your stance on cannabis legalization in Maryland, however I feel that I must rebut one of your points.

You stated that there has been scientific evidence showing that marijuana damages brain cells, but in fact, that is one issue that almost every relevant study agrees upon: cannabis poses no risk to the brain or to an individual’s intellect. I think you may be referring to one recent study which claimed that adolescents and young teens who smoke cannabis may suffer from diminished IQs. But you should note that a follow-up study concluded that the original study was incorrect, stating that the true probable cause of the lower IQs of the test subjects was related to the socioeconimic status of the test subjects, rather than their marijuana usage (source: http://www.pnas.org/content/early/2013/01/09/1215678110.abstract?sid=2376b516-baa1-4ad1-8ba2-98582af25378 ).

Despite the strict restrictions about conducting research on cannabis use, there really have been quite a few studies done (abroad or otherwise). And almost all of them suggest that cannabis is virtually harmless among all users, regardless or age or frequency of use. A major problem we have now is that the federal government (particularly the DEA) puts itself in the position as a be-all-end-all source on drug-related information. They have a very small hand-full of studies (a fraction of the studies that have actually been done), hand picked to weakly suggest that cannabis is harmful. Then they go on to claim that any other studies are invalid because they conflict with their current standards. Even the ones that were funded by the federal government in the first place! I know there is very little you or I could do about this from the state level, but I do hope you will keep an open mind about the subject and attempt to learn more than the limited information you can get from the government itself.

The one thing I most desperately wish from my political representatives is for them to fully embrace science. There are always two sides to every political issue, and everyone has an opposing opinion, but when it comes to science, there is only one truth. And more importantly, scientific conclusions can change as new information is discovered. So, Mr. Ready, if you take anything from this long winded comment, I hope it is that you should continue to educate yourself. Understand the science behind your issues, and always be willing to challenge your own conclusions if new facts are present. Truth should always trump politics.

I too would oppose legalization if the science suggested it would be harmful to the consumers or to society in general. But I have never read a single trustworthy study suggesting such (and I have read up on the subject quite a lot, as you might imagine).

So, all that being said, and hopefully I still have your attention, I truly do appreciate your support of medical marijuana. Not many politicians are willing to acknowledge that an illegal substance could have any benefit at all, so I respect your willingness to take such a bold stance. So, thank you. But recently, more and more politicians are beginning to realize the truth and notice the scientific evidence showing what a helpful medicine this can be. And it really shouldn’t stop there. Many young non-violent people are being thrown into prisons, their lives ruined, simply for choosing to use a relatively harmless substance. Whether you think marijuana is good or bad, you must agree that this situation is wrong. The goal of full legalization is not to promote use, but is rather to prevent the destruction of lives for a simple, harmless life-choice.

  1. There are so many studies that they have to be read collectively and then have investigations to see if the conclusions are found to be true in the population studied.
    There is considerable consensus in the literature about cannabis triggering schizophrenia, and it is explained several ways by several researchers.

    When one goes back to look for the effect in the population at large, the problems begin. When cannabis was made illegal, there were few users. Use has grown steadily more popular despite prohibition over the time period of prohibition, and today it is said that over 100 million living US residents have at least experimented with cannabis. Such a huge upswing of users must mean there was a huge upswing in the incidence of schizophrenia, Right? Wrong! There has been zero increase in schizophrenia over that time period.

    We very much need for science to regulate and punish those that push such obvious lies as science.

  2. Actually it is a myth that people in the Middle Ages believed the Earth was flat, there is much evidence that people were well aware of a spherically structured planet.

  4. i too am an activist and I am working on a BA in health and human services. poor people are not stupid just because they smoke a plant. were there any studies on stress levels and pot. The gateway drug thing was an excuse to get going. Its a choice thing.

  5. This thing has been around forever, it has been used forever in many cultures as well, all i know its safer than ciggeretts alcohol and other prescription drugs, all u have to do is educate yourself, make sure ur getting properly grown stuff with no added chemicals, If this is so harmful why do aids cancer and other patients get medicinal marijuana and it usually adds years to their life

  6. It’s a combination of what you mentioned but also the driving factor behind prohibition is the fact
    that corporation’s profits from its illegal status and most federal lawmakers
    are not willing to risk their seats to these companies that funded their campaigns.
    At the state level some of our lawmakers are affected the same way like here in North
    Carolina where our lawmakers are investors in the companies that will suffer
    from the legalization of Marijuana in our state. Most companies are willing to
    except their hired vote will have to vote yes on Medical Marijuana at some
    point so it’s coming around slowly but it will prevail.

  7. It really seems like the main problem with reaching legalization is that the politicians are either refusing to educate themselves or refuse to believe the facts in favor of personal beliefs. It took a pretty good amount of time to convince people that the Earth is round, and there’s still a few out there that don’t believe it.
