Abstract
Cannabis (Marijuana) use during pregnancy is a growing public health issue across the earth, with potential adverse effects on neonatal outcomes. In Jamaica, where cannabis holds cultural, medicinal, and spiritual significance, prenatal exposure is embedded in unique socio-cultural contexts. This ethnographic study explores patterns of cannabis use during pregnancy, examines neonatal health outcomes, and elucidates cultural beliefs influencing maternal cannabis consumption. Findings reveal that while prenatal marijuana use is common and often viewed as medicinal or spiritual, some neonatal outcomes such as reduced birth weight and shortened gestational age were observed. The study highlights the importance of culturally sensitive health education and calls for longitudinal research to better understand long-term effects.
Notably, at 30 days of age, infants exposed prenatally to marijuana scored more favourably on two specific clusters of the Brazelton Scales: autonomic stability and reflexes. This suggests a transient enhancement in these neurological functions in the exposed group during early neonatal development.
Introduction
Cannabis (marijuana) remains one of the most widely used psychoactive substances across the earth. Its use during pregnancy has attracted increasing attention due to potential risks to fetal development and neonatal health. In Jamaica, cannabis occupies a distinct position influenced by Rastafarianism, traditional medicine and evolving legal frameworks. Despite international studies suggesting prenatal cannabis exposure may affect birth outcomes, data from Jamaica, a country with unique cultural dynamics – are scarce.
This study aims to fill this gap by using ethnographic methods to understand prenatal cannabis use and associated neonatal outcomes in Jamaican communities. It emphasizes the cultural contexts that shape behaviors and health perceptions, seeking to inform effective public health interventions.
Background
Cultural Context of Cannabis in Jamaica
Cannabis has been traditionally used in Jamaica for spiritual, medicinal and recreational purposes. Rastafarian communities regard it as a sacred herb, used in religious rituals and perceived to promote mental and physical well-being. Decriminalization policies implemented in 2015 further influenced public attitudes, reducing stigma and increasing access.
Prenatal Exposure Concerns
Globally, prenatal marijuana use has been linked to several adverse neonatal outcomes including low birth weight, preterm birth and cognitive or behavioral deficits in childhood. The active component tetrahydrocannabinol (THC) crosses the placental barrier, potentially affecting fetal brain development. However, socio-economic, nutritional and environmental factors often confound these associations.
Methodology
Ethnographic Approach
The study employed qualitative ethnographic methods over 12 months in rural and urban communities with high reported cannabis use. Participant observation, semi-structured interviews, and focus groups were conducted with:
Pregnant women who reported cannabis use
Pregnant women who abstained from cannabis
Healthcare professionals
Traditional healers and community elders
Sample and Data Collection
Sample size: 50 pregnant women (30 cannabis users, 20 non-users)
Data points: Cannabis use patterns, motivations, cultural beliefs, prenatal care experiences
Neonatal data: Birth weight, gestational age, Apgar scores, initial health assessments from clinic records
Findings
Patterns and Motivations for Cannabis Use
Cannabis was primarily used for medicinal purposes:
Relief of nausea and vomiting (morning sickness)
Alleviation of back pain and other pregnancy-related discomforts
Induction of relaxation and stress reduction
Usage often decreased during the third trimester due to health advice or personal choice. Cannabis was frequently consumed as herbal teas or smoked. Family and community members commonly provided advice and support regarding use.
Neonatal Outcomes
Analysis of neonatal data revealed:
Average birth weight among exposed newborns was approximately 150-200 grams lower than non-exposed peers.
Slightly higher incidence of preterm births (<37 weeks) in the exposed group, though differences were not statistically significant given the sample size.
No marked differences in Apgar scores or immediate postnatal complications.
No increased rates of neonatal intensive care unit (NICU) admissions.
Developmental testing using the Brazelton Neonatal Behavioral Assessment Scale showed no significant differences between children born to marijuana-using and non-using mothers across most domains. Notably, at 30 days of age, infants exposed prenatally to marijuana scored more favourably on two specific clusters of the Brazelton Scales: autonomic stability and reflexes. This suggests a transient enhancement in these neurological functions in the exposed group during early neonatal development.
Cultural Beliefs and Health Communication
Cannabis use during pregnancy was normalized in many families. Women described cannabis as a “natural medicine” beneficial for both mother and child, reflecting deep-rooted cultural beliefs. Healthcare workers reported discomfort discussing cannabis use due to lack of training and cultural sensitivities. Conflicting information from medical professionals and traditional healers contributed to confusion.
Discussion
This study illustrates the complexity surrounding prenatal cannabis use in Jamaica, where cultural acceptance coexists with emerging health concerns. The observed trends of lower birth weight and slightly shorter gestation align with international findings, although they are influenced by socio-economic and nutritional factors typical in Jamaican communities.
The ethnographic approach highlights the need for culturally adapted interventions that respect traditional beliefs while communicating potential risks. Public health messages should be developed collaboratively with community stakeholders to ensure acceptance and effectiveness.

Recommendations
Culturally sensitive prenatal education: Programs should integrate scientific evidence with local cultural frameworks to provide balanced information on cannabis use risks and benefits.
Healthcare provider training: Equip medical staff with communication tools to discuss cannabis use nonjudgmentally and support informed maternal choices.
Further research: Larger epidemiological and longitudinal studies to evaluate long-term developmental outcomes of prenatally exposed children.
Community engagement: Work with traditional healers and elders to co-create health promotion strategies.
Conclusion
Prenatal marijuana exposure in Jamaica is common and deeply intertwined with cultural practices. This study’s ethnographic insights reveal nuanced motivations for use and suggest some adverse neonatal effects, particularly regarding birth weight. Addressing prenatal cannabis use requires culturally informed health policies that respect Jamaican traditions while safeguarding maternal and child health.
