People believe these scientists when they are not sure what they are doing, but when it comes to your health, people think it is a lie.
Why do you think that kids of today are more sick than kids born before the 1960’s, birth was more natural with less drugs than today, today there are more drugs prescribed for people who are sicker now then years back.
They are trying to ban cigarettes because of health hazards of smoking, then they pass laws on where you can smoke, and then go out and say it is alright to smoke marijuana, and that there is nothing harmful in that, now the only thing harmful in that is that the states and the Government want a way to charge more taxes since they cut their nose off to get more taxes from people to get them quite, but the thing is that if they keep raising taxes, they won’t have any one here to pay them, and if they can get people high they will vote for any tax and the people won’t know what they voted for, Oh it is that way now, they just voted because the lie sounded good.
How about the women who will be around people smoking marijuana, what do you think will happen then, who will they blame when their children are born unhealthy and have to live on some type od drug or some machine, or how about brain-dead, then who will you blame and who will you believe, it will be you, you were the greedy one who had to have marijuana over cigarettes, in most cases drugs have a better chance of killing you quicker or some one else just like alcohol.
But go ahead keep believing that drugs are good for you, and then see what happens and where you end up when you can no longer do your job, and then do you think that the Government will help then.

Marijuana Use During Pregnancy Affects Baby’s Brain

Using marijuana during pregnancy could affect a baby’s brain development by interfering with how brain cells are wired, a new study in mice and human tissue suggests.
“Our advice is that [pregnant] mothers should avoid marijuana,”said neuroscientist Tibor Harkany of the Karolinska Institute in Sweden, and the Medical University of Vienna, in Austria, who led a study detailed today (Jan. 27) in the EMBO Journal.

Harkany added that the effects of prenatal marijuana exposure could even last into adulthood. The drug could have direct effects, or it could sensitize the brain to future drug exposure or neuropsychiatric illnesses.
Pot during pregnancy
Previous studies have found that exposure to marijuana during pregnancy can increase a child’s risk of having cognitive deficits or psychiatric disorders.
While it is not exactly clear how marijuana may affect the fetal brain at a molecular level, it seems the brain may be particularly sensitive to THC (delta-9-tetrahydrocannabinol) during early development, when neurons are forming critical connections. Any drug that interferes with this development could be detrimental to the child, Harkany said.
In the study, Harkany and his colleagues tested marijuana’s effects in three ways: They grew brain cells from mice in the presence of THC, they injected pregnant mice with THC, and they studied the brains of electively aborted human fetuses whose mothers had used marijuana during pregnancy.
The researchers identified a specific protein in nerve cells, called Superior Cervical Ganglion 10 (SCG10), which is essential for normal brain wiring. They found lower levels of this protein in the brains of both human and mouse fetuses exposed to THC compared with individuals who weren’t exposed to THC, suggesting that marijuana exposure has a specific effect on the developing brain.
Marijuana and brain development
“Prenatal cannabis disrupts synapses [nerve connections] critical for higher order executive and cognitive function,” study researcher Yasmin Hurd, a neuroscientist at Mount Sinai Hospital in New York, told LiveScience in an email.
An increasing number of women of childbearing age are using marijuana, and this group should be made aware of the potential impact on the brain development of their children, she said.
Harkany added that pregnant women should avoid using marijuana use for medical purposes.
Previous long-term studies have shown that children exposed to marijuana in the womb may have an increased risk of showing cognitive effects, seeking out drugs, or having attention deficit disorder, anxiety or depression, according to the study.
Harkany and his colleagues didn’t study the effects of marijuana use prior to pregnancy, but he said the drug is cleared from the body in a period days, not months, and using it prior to conception is more likely to affect the likelihood of becoming pregnant than the fetus itself.
So far, Harkany said, no studies have compared the effect of marijuana to that of other drugs, such as alcohol, on fetal brain development.
