Number of new heroin Pregnancy, heroin, McCance-Katz

There was more alarming news. Use of illegal drugs, including cocaine, marijuana, and opioids by pregnant women increased significantly between 2015 and 2017. About 7 percent of pregnant women reported using marijuana. Three percent said they used it daily. 

McCance-Katz says marijuana use is linked to fetal growth problems, preterm births, stillbirths, hyperactivity and impaired cognition in newborns. 

Pregnancy and Breastfeeding Pregnancy, Breastfeeding

The importance of the published findings and the emerging research regarding the potential negative effects of marijuana on brain development are a cause for concern despite the limited research and are the basis for the following recommendations:

  1. Women who are considering becoming pregnant or who are of reproductive age need to be informed about the lack of definitive research and counseled about the current concerns regarding potential adverse effects of THC use on the woman and on fetal, infant, and child development. Marijuana can be included as part of a discussion about the use of tobacco, alcohol, and other drugs and medications during pregnancy.
  2. As part of routine anticipatory guidance and in addition to contraception counseling, it is important to advise all adolescents and young women that if they become pregnant, marijuana should not be used during pregnancy.
  3. Pregnant women who are using marijuana or other cannabinoid-containing products to treat a medical condition or to treat nausea and vomiting during pregnancy should be counseled about the lack of safety data and the possible adverse effects of THC in these products on the developing fetus and referred to their health care provider for alternative treatments that have better pregnancy-specific safety data.
  4. Women of reproductive age who are pregnant or planning to become pregnant and are identified through universal screening as using marijuana should be counseled and, as clinically indicated, receive brief intervention and be referred to treatment.
  5. Although marijuana is legal in some states, pregnant women who use marijuana can be subject to child welfare investigations if they have a positive marijuana screen result. Health care providers should emphasize that the purpose of screening is to allow treatment of the woman’s substance use, not to punish or prosecute her.
  6. Present data are insufficient to assess the effects of exposure of infants to maternal marijuana use during breastfeeding. As a result, maternal marijuana use while breastfeeding is discouraged. Because the potential risks of infant exposure to marijuana metabolites are unknown, women should be informed of the potential risk of exposure during lactation and encouraged to abstain from using any marijuana products while breastfeeding.
  7. Pregnant or breastfeeding women should be cautioned about infant exposure to smoke from marijuana in the environment, given emerging data on the effects of passive marijuana smoke.
  8. Women who have become abstinent from previous marijuana use should be encouraged to remain abstinent while pregnant and breastfeeding.
  9. Further research regarding the use of and effects of marijuana during pregnancy and breastfeeding is needed.
  10. Pediatricians are urged to work with their state and/or local health departments if legalization of marijuana is being considered or has occurred in their state to help with constructive, nonpunitive policy and education for families.
Is CBD Oil Harmful or Healing? What No One is Telling You hash oil, cbd oil, Pregnancy

CBD oil may potentially interact in a negative way with anti-epilepsy drugs. As of now, only in vitro (test tube) observations exist with no living organism testing proving safety. Drugs that may interact include: 

  • carbamazepine (Tegretol)
  • phenytoin (Dilantin)
  • phenobarbital (Luminal, Solfoton, Tedral)
  • primidone (anti-seizure)

Majority of Dispensary Workers Told Undercover Callers Pregnant Women Could Use Pot Pregnancy, Colorado

Researchers had two women conduct "mystery caller" phone conversations with employees at 400 dispensaries across the state, telling them that they were eight weeks pregnant and suffering from morning sickness. During the majority of those calls, the employees recommended the women use cannabis products.

Study shows prenatal cannabis use associated with low birth weights Pregnancy, study

They also discovered that prenatal marijuana use was associated with a 50 percent increased chance of low birth weight regardless of tobacco use during pregnancy. “Growing evidence suggests prenatal cannabis exposure has a detrimental impact on offspring brain function starting in the toddler years, specifically issues related to attention deficit disorder,” Crume said. “But much of the research on the effects of prenatal cannabis on neonatal outcomes was based on marijuana exposures in the 1980s and 1990s which may not reflect the potency of today’s cannabis or the many ways it is used.”

 

Review of the public health risks of widespread cannabis use Pregnancy, car crashes, mental health, pediatrics, Long-term, Doctors, Research, second hand smoke, smoking

1. Legalizing cannabis has been shown to increase the rates of motor vehicle accidents.
2. Cannabis use is a risk factor for mental illness.
3. Inhaled Cannabis use is a risk factor for respiratory infections.
4. Cannabis use increases the rate of vascular disease. Cannabis is the third most often identified drug of abuse
5. Cannabis use during pregnancy has been associated with increased risk of adverse birth outcomes
6. Legalization of cannabis has been shown to increase cannabis exposure in the pediatric population.
7. Heavy cannabis use is associated with diminished lifetime achievements.
Doctors must educate the public about the potential harm cannabis causes with heavy, and possibly moderate, widespread use just as they do about the dangers of tobacco use. Tobacco use has declined in the United States in large part because of the knowledge the public now holds about its adverse effects, as opposed to legislative action.

Study shows link between maternal marijuana use and low birth weight Pregnancy

In a new study, researchers in London, Ontario found that women who used marijuana while pregnant were almost three times more likely to have an infant with low birth weight than women who did not use marijuana.

Marijuana and Pregnancy Pregnancy, 2017 Legislation

Marijuana use during pregnancy can be harmful to your baby’s health. The chemicals in marijuana (in particular,tetrahydrocannabinol or THC) pass through your systemto your baby and can negatively affect your baby’s development.

Here are just a few of the health effects you may want to know:

  • Marijuana use directly affects the brain—specifically the parts of the brain responsible for memory, learning, and attention.
  • The compounds in marijuana can affect the circulatory system and may increase the risk of heart attacks and strokes.
  • Smoking marijuana can lead to a greater risk of bronchitis, cough, and phlegm production.
  • Marijuana users are significantly more likely than nonusers to develop chronic mental disorders, including schizophrenia. Schizophrenia is a type of mental illness where people might see or hear things that aren't really there (hallucinations).
  • Eating foods or drinking beverages that contain marijuana have some different risks than smoking marijuana, including a greater risk of poisoning.
  • About 1 in 10 marijuana users will become addicted. For people who begin using before the age of 18, that number rises to 1 in 6.
  • Some research shows that using marijuana while you are pregnant[288 KB] can cause health problems in newborns—including low birth weight and developmental problems.
  • Marijuana use can slow your reaction time and ability to make decisions when driving[271 KB].

Cannabis use during pregnancy may affect brain development in offspring: Thicker prefrontal cortex Pregnancy, Brain, science daily

Summary: Cannabis use during pregnancy is associated with abnormal brain structure in children, according to a new study. Compared with unexposed children, those who were prenatally exposed to cannabis had a thicker prefrontal cortex, a region of the brain involved in complex cognition, decision-making, and working memory.

Study shows marijuana users twice as likely to give birth prematurely Pregnancy, Studies

For the researchers of the study, the results present a “a major public health concern” as a number of pregnant women would report taking marijuana to alleviate morning sickness or nausea – without knowing of the adverse side-effects.

Highlights

Marijuana increases the risk of spontaneous preterm birth independent of cigarette smoking status and socio-economic status.

Women who continue to use marijuana at 20 weeks’ gestation are five times more likely to deliver preterm than those who do not.

The rate of early SPTB is higher amongst women who continue to use marijuana at 20 weeks’ gestation.

Cannabis During Pregnancy Impairs Baby's Brain Development Pregnancy

Children whose mothers use marijuana during pregnancy have a higher risk of stunted growth and of developing ADHD, anxiety, and depression later in life.
When THC enters the body, it interferes with endocannabinoid’s actions, competing with it for binding sites on target cells and generally getting its way.

 But at a bare minimum, these findings suggest we should be avoiding recreational cannabis use during pregnancy. 

Mother's and marijuana use NIDA, Pregnancy, vidoe, Dr. Genna, Dr. Natacha, interview

My main finding is that it's primarily women who were younger when they become mothers who do continue to use marijuana overtime. Also women who are depressed over longer periods of time, women who smoke, women who use more than the recommended amount of alcohol are more likely to continue to use marijuana while pregnant as well as when they're raising their children. So the take-home messages is to ask women about marijuana use. We know that marijuana use is considered more and more acceptable by women and that they may continue to use while they are pregnant and while they are having children.

Given these statistics.... is legalization worth the consequences....
Cannabis has been found to be the most frequently used drug in the U.S. after alcohol, tobacco and caffeine. 
The risk of developing addiction associated with cannabis use has been reported to increase to about 17% among those who start using marijuana in adolescence, and to 25-50% among those who smoke marijuana daily.
The long-term effects of marijuana use include altered brain development and cognitive impairment, including impaired neural connectivity in specific brain regions, decreased activity in prefrontal regions, and reduced volumes in the hippocampus.
Cannabis is most commonly consumed through smoking, a route of drug delivery that predictably has a variety of negative effects on pulmonary function. Smoke from marijuana combustion has been shown to contain a number of carcinogens and cocarcinogens, as well as many of the toxins, irritants, and carcinogens as tobacco smoke.  Additionally, marijuana smokers tend to inhale more deeply and hold their breath longer than cigarette smokers, which leads to a greater exposure per breath to “tar” (the carcinogenic solids in smoke). Regular smoking of marijuana, in the absence of tobacco, produces visible and microscopic injury to the large airways

Studies show that children exposed to marijuana in utero have lower scores on tests of visual problem-solving, visual and motor coordination, and visual analysis, compared with children not exposed to the drug, the report states. Prenatal marijuana exposure also has been associated with decreased attention span and behavioral problems. The nervous system of a human fetus can respond to the chemicals in marijuana within 14 weeks of gestation, and studies have shown that 14-year-olds are more likely to be marijuana users if their mothers used the drug during pregnancy.

State of the Science   190 resources
Several problems are associated with marijuana use during pregnancy, because prenatal exposure influences brain development and can result in permanent cognitive impairment. [35] Cognitive deficits resulting from prenatal exposure include inattention; impulsivity; and impairment in learning, memory, and certain aspects of executive functioning. [36] In addition, prenatal exposure to cannabis has been associated with reduction of fetal growth. [37]
For many years, the myth of smoked cannabis being "healthier" or "no worse" than smoked tobacco was perpetuated by pro­marijuana groups. Both smoked cannabis and tobacco contain approximately 4000 chemicals and that these chemicals are essentially identical in both plants.In another recent review, [23] the authors concluded that "smoking of cannabis is not medically recommended due to the potential respiratory tract, dangers of noxious compounds such as polycyclic aromatic hydrocarbons, tar and carbon monoxide."

Effects of Marijuana on the Fetus and Breastfeeding Infants. Pregnancy

Cannabis has enormous affinity for milk and produces a milk/plasma ratio of 8, although the levels in milk are generally considered subclinical. THC crosses the placenta readily, and there is increasing evidence that it may increase rates of growth retardation and adverse neurodevelopment following prenatal exposure.
 
One study indicated an increased incidence of reduced head circumference in young adolescents (9-12 years of age) who were exposed in utero to heavy marijuana use.  Prenatal exposure resulted in a higher rate of low birth weight infants and childhood leukemia. Recent studies have suggested a reduction in long and short-term memory retrieval and retention in children exposed to prenatal cannabis. These children were also weak in planning, integration, and judgment skills.
 
While the effect of cannabis on infants from breastfeeding mothers is limited, cannabis use in breastfeeding mothers should be strongly discouraged. Thus, in pregnant and breastfeeding mothers, this drug should no longer be viewed as safe.
