Introduction

Marijuana drug consumption has exponentially increased over the years in many countries. People have become addicted to its usage in cigarettes, pipe blunts, and edibles such as cookies, brownies, tea, and many more because this drug stimulates Dopamine chemicals in the brain producing euphoric and relaxed feelings.

Pregnant or lactating women using marijuana can seriously affect a newborn's health. Various studies have discussed the harmful effects and consequences of consuming marijuana during pregnancy and lactating, affecting both mother and child's health. Therefore, though it is also used for some medicinal purposes, its consumption during pregnancy is strictly not recommended.

What Is Marijuana, Cannabis, or Weed?

Marijuana is obtained from the dried stem, leaves, and flowers of the plant Cannabis sativa or Cannabis indica plant. This plant contains THC (tetrahydrocannabinol), a chemical that alters the brain and nervous system. Marijuana extract includes hash oil, honey oil, the wax used in lip balms, etc. Higher use of this chemical THC increases the risk of drug addiction if a person consumes drugs regularly, having both physical and mental effects on the body.

What Are the Common Names Used for Marijuana?

  • Weed.

  • Cannabis.

  • Joint.

  • Ganja.

  • Hash.

  • Bhang.

  • Charas.

What Are the Effects Of Marijuana on Pregnant Mothers?

  • Reduced placental circulation.

  • High risk of anemia.

  • Increased heart rate.

  • Decrease in blood pressure.

  • Dizziness and confusion.

  • Hallucinations.

  • Vomiting and dehydration.

  • Lung damage causes breathing issues.

  • Impaired memory.

  • Senses get altered.

How Does Marijuana Affect Pregnancy?

  • Stillbirths - Loss of pregnancy or miscarriage after the 20th week due to lifestyle choices or other reasons.

  • Premature Births - This occurs when the delivery occurs three weeks before the due date of pregnancy and the baby is not fully matured, with higher risks of complications.

  • Fetal Growth Stagnation - It happens when a baby weighs less than the average weight, which is 5pounds, 8 ounces. It can happen at any stage during pregnancy, and the fetus does grow well.

  • Brain Development Problems - The brain does not develop appropriately in newborns.

  • Anemia - This happens when babies do not have enough red blood cells to carry oxygen in the body.

  • Congenital Abnormalities - The congenital disability or disorder caused during pregnancy in the fetus or later life after birth.

How Does Marijuana Affect Lactation?

Breastfeeding is essential for an infant's health to fulfill nutritional needs. So, Marijuana usage during the lactation period is not safe for the baby. THC (Tetrahydrocannabinol) in the weed or marijuana gets mixed in the breast milk, passes into the newborn's body, and has long-term effects. It also affects the quality and quantity of milk produced and has brain development disorders.

What Are the Long-Term Effects of Marijuana?

  • Chronic bronchitis and other respiratory infections.

  • Cardiac arrest due to increased heart rate after prolonged smoking.

  • Chronic psychotic disorders like schizophrenia, anxiety, and depression.

  • Driving ability also gets impaired.

  • Frequent withdrawal symptoms.

How Does Marijuana Affect the Brain and Other Senses?

Marijuana or any drug alters the senses by disturbing the signaling process in the brain and how nerve cells (neurons) communicate. As soon as the THC (tetrahydrocannabinol) in marijuana is smoked, it enters the lungs. Then the bloodstream carries it to the brain and other body organs, immediately producing an effect lasting for a few hours. It makes a person confused, lacking concentration and evident decision-making power.

The brain already has cannabinoid receptors that get activated by THC (tetrahydrocannabinol), which activates the endocannabinoid system, a part of the communication system in the brain. It releases Dopamine which produces a sense of pleasure and reward.

What Are Preventive Measures to Quit Marijuana Before Pregnancy?

  • Before and during pregnancy, a good medical history of women before and during pregnancy should be taken by the doctor to know about marijuana usage or any other drug abuse.

  • In detail, the doctor must thoroughly counsel those reporting any history of marijuana, smoking, or drinking about the after-effects and consequences of drug abuse during pregnancy.

  • Doctors can also motivate and guide them properly to stop using these drugs for their health and the newborn's safety and discourage them from using such drugs shortly.

  • They should be educated adequately about drug detoxification and psychological counseling options as part of the de-addiction and treatment programs.

How Can We Treat Marijuana Addiction?

  • Cognitive-Behavioral Therapy: This psychotherapy helps people understand their underlying behavior, thought process, or mood and enhances their self-control power to stop using drugs. It helps a person deal with uncontrollable negative thoughts leading to anxiety and depression.

  • Motivational Enhancement Therapy: It is a type of counseling for a person which could motivate him to change internally through his own will. This therapy does not usually treat a person but motivates him for a positive change. The treatment is also used for people showing self-destructive behavior.

  • Contingency Management: This therapy is used in cases of substance use to give people rewards and incentives for showing positive behavioral changes after monitoring their behavior repeatedly. In this therapy, a motivational reward or prize is given to a person for achieving a specific treatment goal in the substance use de-addiction process to motivate his willpower.

Conclusion:

Cannabis or marijuana consumption has shown some evident fetal growth abnormalities and developmental issues and deformities in various studies. Women addicted to weed consumption in any form during pregnancy do not prove safe for the child and their health. Obstetrician-gynecologists do not advise marijuana to pregnant women, women planning for a baby, or during lactation. Therefore, drug-abuse women should be given proper knowledge about its complications in pregnancy and must be discouraged from marijuana during pregnancy. Moreover, we must counsel or offer help to people around us addicted to its usage and make them understand its long-term effects on their well-being.

Frequently Asked Questions

1.

What Happens if a Pregnant Woman Smokes?

Smoking during pregnancy can harm the fetus' tissue, especially in the lungs and brain. Some studies have found a connection between maternal smoking and the occurrence of cleft lips in babies. Studies have also shown a link between smoking and miscarriage. Apart from this, stillbirth or preterm delivery are also potential dangers of smoking during pregnancy. In addition, smoking inhibits the baby's oxygen supply. After smoking each cigarette, the baby's movements in the womb become less vigorous for at least an hour.

2.

What Happens if a Pregnant Lady Smokes During the First Few Weeks of Pregnancy?

Smoking during the first few weeks or first trimester of pregnancy increases the chance of pregnancy complications like placental abruption (when the placenta separates from the implantation), placenta praevia (when the placenta attaches itself over or extremely close to the cervix), low birth weight, and preterm birth which can have negative impacts on a baby's general health in the long run. Compared to infants of normal weight, low birth weight babies are more prone to experience major health issues in childhood and adulthood.

3.

Is Vaping Safe for a Pregnant Woman?

It is not safe to use electronic cigarettes (vaping) when pregnant. Most e-cigarettes contain nicotine, which irreversibly harms a baby's growing brain and other organs. E-cigarette liquids may also contain chemicals, flavors, and other additives that are harmful to the baby and may cause birth defects.

4.

What Medications Can Be Used to Treat Anxiety When Pregnant?

Medication may be an option for pregnant women if anxiety is severe. Tricyclic antidepressants and selective serotonin reuptake inhibitors (SSRIs) are considered safe during pregnancy. Research shows that there is no increased risk of significant congenital deformity in infants exposed to these drugs in utero, and they are beneficial for treating anxiety disorders. Furthermore, no strong evidence links these drugs to any major pregnancy concerns.

5.

Can a Midwife Detect Smoking?

The pregnant woman will be requested to perform a quick breath test for carbon monoxide at the scheduling consultation with the midwife. Carbon monoxide is a gas released by appliance malfunctions, exhaust fumes, and cigarette smoke. Women who smoke during pregnancy and their unborn babies are seriously injured by carbon monoxide.

6.

In Which Week Should a Pregnant Woman Stop Smoking?

Smoking cessation at any point throughout the pregnancy benefits both mother's and baby's health. The infant will receive more oxygen after just one day of quitting smoking. This will promote healthy lung development in the child. Quitting as early as possible during pregnancy also lessens the probability of giving birth to an underweight child. However, the optimal time to stop is before 16 weeks, but stopping after this point is still good, according to the recommended advice.

7.

Can Marijuana Use While Pregnancy Lead To ADHD?

Marijuana use during pregnancy has been linked to mental health issues in children. According to a new study, prenatal cannabis exposure is linked to an increased risk of behavioral problems like getting ADHD (attention-deficit/hyperactivity disorder) and violent conduct in early adolescence.

8.

What Is the Most Well-Known Consequence of Smoking During Pregnancy?

The well-known side- effects of smoking during pregnancy are listed below:
- Ectopic pregnancy (a pregnancy that occurs outside the uterus, generally in the fallopian tube).
- Stillbirth (death of an unborn child in the womb).
- Birth defects in the baby.
- Premature baby.
- Low birth of the baby.
- Slow growth and development of the baby.

9.

Can Smoking Cause Learning Impairments During Pregnancy?

Studies have revealed that children exposed to prenatal and ambient tobacco smoke are about three times more likely than those without a learning disability. Smoking negatively affects the development of a baby’s brain during pregnancy, resulting in this disability.

10.

What Birth Defects Do Smoking Cause?

Smoking during pregnancy increases the likelihood of the baby being born with birth problems. Congenital heart abnormalities and structural heart disorders, like defects in heart structures, are the most common sorts of problems. Cleft lip and palate are other health concerns associated with smoking during pregnancy.

11.

Is It Possible to Determine if Someone Is a Smoker by Their Placenta?

Smokers' placentas are smaller and rounder than that of non-smokers. The vasculature of the placenta is impacted by smoking during pregnancy. Fetal undernourishment is more likely because smoking may alter the placental blood flow and reduce the area for gas and food exchange between the mother and the fetus. In addition, unusual placenta positions like placenta praevia can also occur in a smoker's pregnancy.
