Cannabis Use in Pregnancy: 10-Year Study Findings
Cannabis use during pregnancy is a topic that often invokes strong opinions, fierce emotions and societal biases on both sides of the discussion. Some in the “pro-cannabis” camp either have an impression that cannabis can do no harm at all, or that the potential benefits far outweigh the potential benefits. On the other side of the debate, the “anti-cannabis” camp often paints a doomsday perspective that cannabis is harmful in any amounts, and in all circumstances.
The study presented here, “Predictors for Cannabis Cesssation During Pregnanc y: A Ten-Year Cohort Study,” published in the Journal of Psychosomatic Obstetrics & Gynecology, takes a tour through this intensely complex issue by exploring the factors that influence cannabis discontinuation during pregnancy and its impact on neonatal outcomes.
What is the Study All About
This study took place over ten years at a hospital in Barcelona, Spain. It involved 142 pregnant women who either reported using cannabis or tested positive for THC. The researchers aimed to find out what factors helped women quit cannabis during pregnancy and how stopping cannabis use impacted their newborns. They looked at things like the women’s backgrounds, pregnancy details, and mental health support.
Key Findings
-
- Cannabis Discontinuation Rates:
- About 24.6% of the women stopped using cannabis during pregnancy.
- Women who were identified as cannabis users during their pregnancy were much more likely to quit than those identified at the time of birth.
- Predictive Factors for Discontinuation:
- First-Time Mothers: Women who were pregnant for the first time were more likely to stop using cannabis.
- Early Detection and Mental Health Support: Women who were identified as cannabis users early in their pregnancy and received mental health support were much more likely to quit.
- Mental Health Interventions: Counseling and support from mental health professionals played a significant role in helping women stop using cannabis.
- Neonatal Outcomes:
- Babies born to mothers who quit cannabis had better outcomes, including lower rates of preterm birth, higher birth weights, and fewer admissions to intensive care units.
- Cannabis Discontinuation Rates:
What Does This All Really Mean? A Discussion:
These findings highlight how important early detection and mental health support are in helping pregnant women stop using cannabis. But they also raise questions about our societal attitudes towards cannabis use, especially during pregnancy.
Reconsidering Implicit Bias
As noted above, many in society view any cannabis consumption negatively, especially during pregnancy. This study encourages those who prefer independent, critical thinking to reconsider and examine these biases by considering WHY pregnant women might use cannabis in the first place:
- Perceived Benefits: Many women use cannabis to manage pregnancy-related symptoms like nausea, anxiety, and pain. They believe it helps and doesn’t harm the fetus, and sometimes see it as safer than traditional medications.
- Mistrust in Traditional Healthcare: Some women prefer cannabis over pharmaceuticals due to negative past experiences with the healthcare system or concerns about the safety of prescribed medications.
What If …. Cannabis Use Was Banned? (Thought experiment)
If cannabis use were forcibly prohibited, what would happen to these women? Let’s consider what the “alternative might be, and suggest a few potential outcomes:
- Increased Suffering: These women have chosen cannabis of their own free will. With the available information, seeing and hearing from the doctors that they see, and learning from the media and friend groups that they have. So… without cannabis, women who rely on it for symptom relief might experience more discomfort and distress, no?
- Forced Medication: If they are “really” ill, should these women be forced (either directly or indirectly) to take medications they don’t want to? Does this not raise ethical concerns about their right to choose their own treatment?
- Risk of Stigma and Judgment: Pregnant women using cannabis face significant stigma and shaming already – wouldn’t we expect this to turn them away from cannabis? If they are shamed for consuming cannabis, as they are today – are we not worried that they will be discouraged from seeking prenatal care or disclosing their substance use? Do we not want everyone to be open and honest with their healthcare providers?!
The Role of Healthcare Providers
Healthcare providers have a crucial role in addressing cannabis use during pregnancy. Instead of imposing blanket bans or judgments, they should:
- Provide Non-Judgmental Support: Have open, empathetic conversations with pregnant women about their cannabis use, understand their reasons, and provide evidence-based information about the risks.
- Promote Informed Decision-Making: Give women accurate information so they can make informed choices about their health and their baby’s health.
- Offer Alternatives: Suggest alternative treatments that might offer similar benefits without the potential risks associated with cannabis use during pregnancy.
My Summary Thoughts
The study “Predictors for Cannabis Cessation During Pregnancy: A 10-Year Cohort Study” provides important insights into the factors influencing cannabis discontinuation and its impact on neonatal outcomes. There may be real concerns with pregnant women consuming cannabis, and very real impact on the growing fetus. Whether these are “meaningful” or truly shaping the fetus in lifelong ways (whether bad, or possibly even beneficial) is not yet clear to science. We know that, in some cases, babies are born early, and in some cases babies are born with lower birthweights. We don’t know whether this is “clinically significant,” that is, whether this makes a difference in the life of the baby, in a way which is permanently harmful. Science does not yet know this.
This paper challenges us to reconsider our perspective and our biases and approach towards pregnant women who do use cannabis. By fostering a more understanding, compassionate, and supportive healthcare environment, we can better address the needs and concerns of these women, ensuring healthier outcomes for both mothers and their babies.
Ultimately, the choice to care about oneself with medicines, especially during such a personal and vulnerable time as pregnancy, is a matter of basic human freedom and personal choices. Society and healthcare systems should respect and support this choice, providing the necessary resources and information to help women make the best decisions for themselves and their children.
