Jetsfan0099 Icon : (18 August 2014 - 03:51 PM) Milliner did suffer a high ankle sprain, that sucks. could linger all year
Jetsfan0099 Icon : (18 August 2014 - 03:52 PM) I think Patterson sucked vs the Colts because he was injured, which he always is.
Mr_Jet Icon : (18 August 2014 - 06:49 PM) As much as people criticized Tannanbaum for spending too much. It's starting to look like Idzik is going to be too cheap.
Mr_Jet Icon : (18 August 2014 - 06:52 PM) You get what you pay for and when you let quality players go because you don't want to pay them, this is what happens. You're left with scrub players.
azjetfan Icon : (18 August 2014 - 07:55 PM) I'm still on board with the Idzik plan. Even with Revis and Revis we still are not going to the SB this year. But the down time sucks. If Milliner comes back healthy by week 3 or so we should be fine.
Mr_Jet Icon : (18 August 2014 - 08:18 PM) Regardless of our SB chances this year or next year. If Idzik keeps acting like a cheapskate and continues to let quality players go, we won't have to worry about winning much of anything this decade.
azjetfan Icon : (18 August 2014 - 09:36 PM) He wants to build through the draft. Not blow the bank on FA. I get what your saying but there is a balance and right now we are not one or two pieces away.
Mr_Jet Icon : (18 August 2014 - 11:00 PM) It's not about being one or two pieces away. It's about keeping the good pieces you have and building upon that.
Mr_Jet Icon : (18 August 2014 - 11:04 PM) But there is no sense in trying to build through the draft if he's only going to end up letting the good players he picks up go in FA after a few years. All because he wants to do things on the cheap.
Jetsfan0099 Icon : (19 August 2014 - 07:02 AM) FIRE IDZIK
azjetfan Icon : (19 August 2014 - 08:33 AM) out side of Revis who left we should have kept?
azjetfan Icon : (19 August 2014 - 08:34 AM) The Revis deal sucks but $16 million was too much for a CB and once he was gone he was not coming back.
Mr_Jet Icon : (19 August 2014 - 11:00 AM) Matt Slauson
azjetfan Icon : (19 August 2014 - 01:00 PM) Eh. I think with our current cap situation we will be able to retain guys like Wilkerson and whomever we want to keep. We are in a good position right now.
Mr_Jet Icon : (19 August 2014 - 01:49 PM) Time will tell.
Jetsfan115 Icon : (19 August 2014 - 02:00 PM) landed revis abck. got DRC, nope we take patterson who got owned and always hurt. milner always hurt. 3rd round CB done for season. were gonna get passed on all day
azjetfan Icon : (19 August 2014 - 02:44 PM) Yea the DRC bit makes me iffy
Jetsfan115 Icon : (19 August 2014 - 03:35 PM) better then patterson
azjetfan Icon : (19 August 2014 - 05:45 PM) No I mean the fact that he whiffed on him.
azjetfan Icon : (19 August 2014 - 05:46 PM) I'm not saying Idzik is perfect. I just like the direction we are heading. It's going to take some patience.
RetireChrebet Icon : (19 August 2014 - 06:27 PM) I like how our lack of secondary is the hot topic right now. The bigger issue is we still will not be able to throw the ball. We are not going to do much of anything regardless until we get a QB. Sorry for being so negative just my honest opinion.
RetireChrebet Icon : (19 August 2014 - 06:29 PM) With that said I think our running game with CJ and Powell will be top 10 or somewhere around there
Jetsfan115 Icon : (19 August 2014 - 06:35 PM) i have faith that if geno messes up that vick can come in and do well. but i have 0 faith in our secondary right now which has been our strong point for the past 4 years or so
MikeGangGree... Icon : (19 August 2014 - 07:35 PM) I agree 115. but the one thing is Rex has done some good things in the past with shitty DBs and still had a solid D going back to his years in BAL

MikeGangGree... Icon : (19 August 2014 - 07:41 PM) SNOOPY BOWL FRIDAY!!!
MikeGangGree... Icon : (19 August 2014 - 07:41 PM) WOOOOOOOOOOOOO
azjetfan Icon : (19 August 2014 - 08:26 PM) I assume we will pick up a guy after the cuts happen.
Jetsfan0099 Icon : (19 August 2014 - 10:14 PM) we'll see but I think we see better QB play than we have in a while.
518-JeTS-FaN Icon : (20 August 2014 - 08:54 AM) disgusted with my local programming, instead of jets and giants they are airing the raiders vs packers..wtf
HarlemHxC814 Icon : (20 August 2014 - 09:23 AM) Glad I don't live up there anymore haha
ganggreen2003 Icon : (20 August 2014 - 06:59 PM) The JETS are #6 in the Forbes List for most franchise value
ganggreen2003 Icon : (20 August 2014 - 06:59 PM) The Buffalo Jills are #31 and the Miami Dolphags are #16 respectively
ganggreen2003 Icon : (20 August 2014 - 07:00 PM) The JETS are worth $1.8 billion
jet-man Icon : (20 August 2014 - 10:03 PM) that's less than the clippers
HarlemHxC814 Icon : (Yesterday, 01:07 PM) I'm very excited with the amount of preseason touchdowns the Jets have
Jetsfan0099 Icon : (Yesterday, 03:21 PM) FIRE IDZIK
Jetsfan0099 Icon : (Yesterday, 07:22 PM) Calvin Pryor and Darrin Walls will start tomorrow
ganggreen2003 Icon : (Yesterday, 08:52 PM) The SIMPSONS MARATHON has been on for almost 12 hours...
Jetsfan0099 Icon : (Yesterday, 08:57 PM) Sanchez looks so much more confident and better in Chip's offense than he did with us
ganggreen2003 Icon : (Yesterday, 09:50 PM) EVERY SIMPSONS EVER!!!!!
2JBallar01 Icon : (Today, 07:10 AM) Sanchez is looking good for the eagles. Crazy how a good offense and the right system can make you look so much better. When you're put into a situatuon to succeed, magic happens. Happy for Sanchez, i think he needed a change just as much as the Jets did.
HarlemHxC814 Icon : (Today, 08:02 AM) Preseason doesn't matter at all
Jetsfan115 Icon : (Today, 11:10 AM) anyone have a stream for the preseaosn agme by chance?

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.
