I thought this would be a good idea to post this. Its on reddit, but here are the details of the findings:
Delaying pot smoking to age 17 is better for teens' brains, a new study suggests
Adolescents who smoke marijuana as early as 14 do worse by 20 on some cognitive tests and drop out of school at a higher rate than non-smokers. But if they hold off until age 17, they're less at risk.
The more teenagers delay smoking marijuana until they're older, the better it is for their brains, but there may be little ill effect if they start after age 17, says a new Université de Montréal study.
Adolescents who smoke pot as early as 14 do worse by 20 on some cognitive tests and drop out of school at a higher rate than non-smokers, confirms the study, published Dec. 29 in Development and Psychopathology, a Cambridge University Press journal.
"Overall, these results suggest that, in addition to academic failure, fundamental life skills necessary for problem-solving and daily adaptation [...] may be affected by early cannabis exposure," the study says.
However, the cognitive declines associated with cannabis do not seem to be global or widespread, cautioned the study's lead author, Natalie Castellanos-Ryan, an assistant professor at UdeM's School of Psychoeducation.
Her study found links between cannabis use and brain impairment only in the areas of verbal IQ and specific cognitive abilities related to frontal parts of the brain, particularly those that require learning by trial-and-error.
In addition, if teenagers hold off until age 17 before smoking their first joint, those impairments are no longer discernible. "We found that adolescents who started using cannabis at 17 or older performed equally well as adolescents who did not use cannabis," said Castellanos-Ryan.
Of 294 teens, roughly half smoked potIn the study, she and her team of researchers at UdeM and CHU Saint-Justine, the university's affiliated children's hospital, looked at 294 teenagers who were part of the Montreal Longitudinal and Experimental Study, a well-known cohort of 1,037 white French-speaking males from some of the city's poorer neighbourhoods. The teenagers completed a variety of cognitive tests at ages 13, 14 and 20 and filled out a questionnaire once a year from ages 13 to 17 and again at 20, between 1991 and 1998.
Roughly half – 43 per cent – reported smoking pot at some point during that time, most of them only a few times a year. At 20 years of age, 51 per cent said they still used the drug. In general, those who started early already had poor short-term memory and poor working memory (that is, the ability to store information such as a phone number long enough to use it, or follow an instruction shortly after it was given). Conversely, the early users also had good verbal skills and vocabulary; Castellanos-Ryan suggested one possible explanation: "It takes quite a lot of skills for a young adolescent to get hold of drugs; they're not easy-access.
She and her team found smoking cannabis during adolescence was only linked to later difficulties with verbal abilities and cognitive abilities of learning by trial-and-error, and those abilities declined faster in teens who started smoking early than teens who started smoking later. The early adopters also tended to drop out of school sooner, which helped explain the decrease in their verbal abilities. "The results of this study suggest that the effects of cannabis use on verbal intelligence are explained not by neurotoxic effects on the brain, but rather by a possible social mechanism: Adolescents who use cannabis are less likely to attend school and graduate, which may then have an impact on the opportunities to further develop verbal intelligence,” said Castellanos-Ryan.
Besides filling out questionnaires about their use of drugs and alcohol over the previous year, the boys participated in a number of tests to measure their cognitive development. For example, they were given words and numbers to remember and repeat in various configurations, were asked to learn new associations between various images, played a card game to gauge their response to winning or losing money, and, in a test of their vocabulary, had to name objects and describe similarities between words. In general, those who performed poorly in language tests and tests that required learning by trial-and-error, either to make associations between images or to detect a shift in the ratio of gains to losses during the card game, reported smoking pot in their young teens.
'We have to be realistic'What should be the takeaway from the study?
"I think that we should focus on delaying onset (of marijuana use)," said Castellanos-Ryan, who next intends to study whether these results can be replicated in other samples of adolescents and to see if cannabis use is associated with other problems, such as drug abuse, later in life. Prevention is especially important now, she added, since marijuana is much more potent than it was in the 1990s, and because teenagers today have a more favourable attitude to its use, viewing marijuana as much less harmful than other recreational drugs.
"But it is important to stick to the evidence we have and not exaggerate the negatives of cannabis," she cautioned. "We can't tell children, 'If you smoke cannabis you're going to damage your brain massively and ruin your life.' We have to be realistic and say, 'We are finding evidence that there are some negative effects related to cannabis use, especially if you start early, and so, if you can hold off as long as you can – at least until you're 17 – then it's less likely there'll be an impact on your brain.'"

And as always, if your trying to quit smoking weed and improve your life and cognitive abilities, I have resource available on my page and a quite weed guide too.
Dependence vs. Addiction
Dependence means needing a drug to feel physically okay. Kinda like Coffee! It doesn’t necessarily mean you are addicted—for example, many people can be dependent on a prescribed medication without being addicted. The difference is that people that are addicted start to think about the drug all the time and make it a higher priority than other things in their life; they often make bad decisions that work against their health and their overall well-being. In the case of a medication, they may start to abuse it (using it differently than how the doctor has prescribed) by taking more of it or crushing it and injecting it. Or in the case of a drug like marijuana, they will be unable to stop using it even though it is causing problems with school, jobs, or relationships. People with addictions are often unable to see—or admit—that this is happening.
One part (but not the only part) of being addicted to a drug is needing the drug to feel physically okay—a condition that is called dependence (see box, “Dependence vs. Addiction”). A person with dependence feels bad when they don’t have the drug, and having enough of a supply is always important to them.
That Bad Feeling …
… is called withdrawal. It’s what leads a lot of people who are addicted to a drug to relapse—meaning, they have tried to quit, but start taking the drug again.
A new study in the Journal of Addiction Medicine shows that teens who use marijuana heavily can experience withdrawal when they stop using it. In a study of teens receiving drug abuse treatment at an outpatient clinic, nearly half of them (40 percent) experienced symptoms of withdrawal when they stopped using marijuana.
Not Just a Crummy Day
From portrayals in movies and on TV of people addicted to heroin, people have an image of drug withdrawal as sweating, shaking, and being curled up in bed with unbearable pain. Marijuana withdrawal is a lot more subtle, but every bit as real.
The main mental symptoms of marijuana withdrawal include:
Some people having marijuana withdrawal might not realize it and that is the hard part. Some of the symptoms just contribute to being in a lousy mood, and it’s often easy to blame that feeling on other people annoying you or just having a bad day. You can also have physical symptoms like:
In the Journal of Addiction Medicine study, teens who had marijuana withdrawal symptoms were more likely than other marijuana users to have problems like difficulties at school or at work or trouble with relationships or money. They were also more likely to have other signs of marijuana dependence and mood disorders like depression.
If you’re worried you may have a problem with marijuana or any other drug, this page may help answer your questions and let you know what to do to get help. It's the guide I used to help me stop smoking weed.
Tell me in the comments: Do you know any regular marijuana users who stop using marijuana and experience the withdrawal symptoms described in this post?
Good evening! I wanted to give everyone an update on my progress since I've recently quit weed. Well, its been almost a year now since I started this site. Not much has changed though, this May it will be one year.
Some things I've learned along the way:
1. Choose your friends wisely.
2. Try to smile and be thankful for what you have.
3. When in doubt and thinking of smoking, stop, drop and roll! LOL.
4. If you need help, try looking at my resources section or the guide that I used.
Welp, I'll keep this short and simple folks.
Have a good day!
