RetireChrebet Icon : (22 March 2015 - 01:28 PM) Haha I'm jk man, but my point was if you've never seen virginia play you would know they weren't going anywhere. Their offense is just painful to watch.
ROBJETS Icon : (22 March 2015 - 03:46 PM) Lol....point taken. But a couple of things. 1 you do realize Nova and Va are in the same bracket right? 2 at least Va lost to a top 25 ranked opponent. Nova lost to an unranked.
ROBJETS Icon : (22 March 2015 - 03:49 PM) Also VA beat some good teams. Lost to Duke,beat Maryland and split games with NC and Louisville. Their wins against quality and ranked opponents was higher and better than Nova.
ROBJETS Icon : (22 March 2015 - 03:55 PM) NC State didn't even get one vote to be in the top 25

ROBJETS Icon : (27 March 2015 - 02:37 AM) London is 4 hours ahead of east coast U.S. Bellator prelims are 7pm Friday night U.S. East Coast time and the main card is 9pm So just add 4 hours to that if you can catch either. Im sure you can catch a stream or use a U.S. VPN if you dont have access to Spike.com. You guys might get Bellator on another channel their just like with the UFC.
ROBJETS Icon : (27 March 2015 - 02:47 AM) Anyway only reason I mentioned it was because of your sense of humor. The last Bellator 134 was called the British Invasion. If you watch mma Might want to add this site to your favorites http://www.mmauk.net...y/bellatornews/

ROBJETS Icon : (27 March 2015 - 02:57 AM) By the way 135 is tonight if you are interested. I used to watch pretty much all the televised mma now I stick with Bellator and UFC only
ROBJETS Icon : (27 March 2015 - 03:07 AM) that last link is a UK mma site. Only reason i added it. http://www.sherdog.com/ is pretty much the best mma site on the net for everything mma
JSOTF Icon : (27 March 2015 - 07:08 AM) I actually live in Germany

The multi-disciplinary study showed that people who started smoking cannabis as teenagers may suffer from IQ decline when they're in their thirties.

Persistent cannabis users who started using the drug before age 18 show an average IQ decline of 8 points and other signs of impaired mental functioning by age 38, according to world-first research emerging from the University of Otago’s long-running Dunedin Multidisciplinary Study.

The Study has followed the progress of 1000 Dunedin-born people since their birth in 1972/73 and is one of the most detailed studies of human health and development ever undertaken. The latest findings are newly published in a paper appearing in the US journal PNAS Plus co-authored by researchers from Otago, Duke University and King’s College London.

Below is a fact sheet of the study produced by the researchers.

The findings:

We studied the association between persistent cannabis use and IQ decline and asked whether IQ decline was concentrated among adolescent-onset cannabis users. Findings come from the Dunedin Multidisciplinary Health and Development Study. The study has followed a group of 1,037 children, who were born in 1972-73 in Dunedin, New Zealand, from birth to age 38 years, with 96% of the sample taking part at age 38. IQ was tested at age 13, before cannabis use, and again at age 38, after some study members had used cannabis for many years.

We found that:

1. Adolescent-onset cannabis users, but not adult-onset cannabis users, showed marked IQ decline from childhood to adulthood. For example, individuals who started using cannabis in adolescence and used it for years thereafter showed an average 8-point IQ decline.
2. Quitting or reducing cannabis use did not appear to fully restore intellectual functioning among adolescent-onset former persistent cannabis users.
3. IQ decline could not be explained by alcohol or other drug use or by reduced years of education among persistent cannabis users.
4. Third-party informants (e.g., friends, relatives) reported noticing more attention and memory problems in everyday life among persistent cannabis users (e.g, losing focus when they should be paying attention, forgetting to do errands, return calls, pay bills).
Why are these findings important?

The importance of “before and after” IQ testing. Previous studies have suggested that adolescents may be particularly vulnerable to the effects of cannabis on IQ. However, until now, research had not been able to rule out the possibility that poorer IQ test performance among adolescent-onset cannabis users predates cannabis-use initiation. We showed that regardless of their initial (pre-cannabis) test performance, adolescent-onset cannabis users performed worse than non-users and adult-onset cannabis users later when they were tested in adulthood.

The findings are consistent with speculation that cannabis use in adolescence, when the brain is undergoing critical development, may have neurotoxic effects.

What is the size of the IQ decline? The extent of IQ decline among adolescent-onset persistent cannabis users (approximately 8 points) is non-trivial. For example, an average person has an IQ of 100, placing them in the 50th percentile for intelligence compared to their same-age peers. If this average person loses 8 IQ points, they drop from the 50th to the 29th percentile for intelligence.

Why is an 8-point decline in IQ significant? Research has shown that IQ is a strong determinant of a person’s access to a college education, their lifelong total income, their access to a good job, their performance on the job, their tendency to develop heart disease, Alzheimer’s disease, and even early death. Individuals who lose 8 points in their teens and twenties may be disadvantaged, relative to their same-age peers, in most of the important aspects of life and for years to come.

How many people does this affect? Only approximately 5% of the 1,037 individuals born in one year in Dunedin became ‘adolescent-onset’ cannabis users. Thus, any effect of cannabis on the brain is confined to a relatively small segment of the population. Nonetheless, findings are concerning given that fewer adolescents today believe that cannabis use presents a serious health risk.

How we measured cannabis use:

We measured cannabis use in two ways: cannabis dependence and regular cannabis use. Persistence of cannabis dependence was defined as the total number of study waves out of five (ages 18, 21, 26, 32, and 38) at which a study member met criteria for cannabis dependence. Study members were grouped according to their number of dependence diagnoses: (a) those who never used cannabis at any study wave and thus could not have become dependent; (b) those who used cannabis at least once at one or more study waves but never diagnosed; © those who diagnosed at one wave; (d) those who diagnosed at two waves; and (e) those who diagnosed at three or more waves.

Cannabis dependence is a substance-use disorder as defined in the Diagnostic and Statistical Manual of the American Psychiatric Association (known as DSM-IV). The purpose of the DSM-IV diagnosis is to predict a patient’s future prognosis, and to identify which patients are most in need of scarce treatment resources. A diagnosis of cannabis dependence generally reflects an individual’s continued use of cannabis despite experiencing significant health, social, and/or legal problems related to cannabis use.

Persistence of regular cannabis use. Because some people use cannabis on a regular basis but never develop problems, we also examined neuropsychological decline as a function of persistent regular cannabis use. This was defined as the total number of study waves out of five at which a study member reported using cannabis four or more days per week (the majority of days in a week). Study members were grouped as those who: (a) never used cannabis; (b) used but never regularly; © used regularly at one wave; (d) used regularly at two waves; and (e) used regularly at three or more waves.

Results were similar for persistent cannabis dependence and persistent regular cannabis use.

How we defined adolescent-onset cannabis use:

We defined adolescent-onset cannabis in two ways: 1) cannabis dependence before age 18 or 2) weekly cannabis use before age 18. Results were similar across both definitions.
How we measured IQ

We assessed intelligence in childhood (ages 7, 9, 11, and 13) and again in adulthood at age 38 using standard tests for the field.
How we measured everyday life cognitive functioning

Study members nominated people "who knew them well." These informants were mailed questionnaires and asked to complete a checklist, including whether the study member had problems with their attention (e.g., “can’t concentrate, mind wanders) and memory (e.g., forgets to do errands, return calls, pay bills) over the past year at age 38.
What additional research is needed?

Our findings suggest that cannabis use before age 18 predicts impaired mental functioning. However, we do not know how much cannabis needs to be consumed and across what ages before impairment occurs. Given that the brain undergoes dynamic changes from the onset of puberty through early adulthood, this developmental period should be the focus of future research on the age(s) at which harm occurs.

Additional research is needed to determine whether cannabis-related IQ decline is reversible. We found that adolescent-onset cannabis users performed worse in adulthood than in childhood even after they had quit or reduced their use for a year or more as adults. This suggests that quitting or reducing use does not fully restore functioning among adolescent-onset cannabis users in this time, but longer-term follow-up is needed.

Findings are limited to a cohort of individuals born in Dunedin, New Zealand in the 1970s. Additional research is needed to determine if similar effects are seen in other countries and in today’s teenagers.
