  • Maternal Use of Cannabis and Pregnancy Outcome
    BJOG: an International Journal of Obstetrics and Gynaecology January 2002, Vol. 109, pp. 21–27 Maternal use of cannabis and pregnancy outcome David M. Fergussona, L. John Horwooda, Kate Northstoneb,*, ALSPAC Study Teamb Objective To document the prevalence of cannabis use in a large sample of British women studied during pregnancy, to determine the association between cannabis use and social and lifestyle factors and assess any independent effects on pregnancy outcome. Design Self-completed questionnaire on use of cannabis before and during pregnancy. Sample Over 12,000 women expecting singletons at 18 to 20 weeks of gestation who were enrolled in the Avon Longitudinal Study of Pregnancy and Childhood. Methods Any association with the use of cannabis before and during pregnancy with pregnancy outcome was examined, taking into account potentially confounding factors including maternal social background and other substance use during pregnancy. Main outcome measures Late fetal and perinatal death, special care admission of the newborn infant, birthweight, birth length and head circumference. Results Five percent of mothers reported smoking cannabis before and/or during pregnancy; they were younger, of lower parity, better educated and more likely to use alcohol, cigarettes, coffee, tea and hard drugs. Cannabis use during pregnancy was unrelated to risk of perinatal death or need for special care, but, the babies of women who used cannabis at least once per week before and throughout pregnancy were 216g lighter than those of non-users, had significantly shorter birth lengths and smaller head circumferences. After adjustment for confounding factors, the association between cannabis use and birthweight failed to be statistically significant ( P ¼ 0.056 ) and was clearly non-linear: the adjusted mean birthweights for babies of women using cannabis at least once per week before and throughout pregnancy were 90g lighter than the offspring of other women.

  • Cannabis & Human Milk
    CANNABIS & HUMAN MILK Two recent studies about cannabis use while breaseeding, both done with Colorado connecons, may have implicaons for your paents. With marijuana use during pregnancy and lactaon on the rise due to legalizaon in more states, these researchers are filling a gap in knowledge about this important health topic. The first study, conducted by Thomas Hale PhD and colleagues, looked at the transfer of tetrahydrocannabinol (THC) into human milk aer maternal inhalaon of a prescribed amount of cannabis. Eight anonymous women from Colorado enrolled in the study and were instructed to disconnue any cannabis use for 24 hours, provide a sample of their milk, then smoke the prescribed amount of cannabis and collect milk at 20 minutes, one, two and four hours. The results showed that THC was transferred into milk at 2.5% of the maternal dose. The second study, done by researchers at the University of Colorado (CU) School of Public Health, used Pregnancy Risk Assessment Monitoring System (PRAMS) data from 2014 and 2015. In this group, 5.7% reported using marijuana during pregnancy and 5% during breaseeding. They discovered that prenatal marijuana use was associated with a 50% increased chance of low birth weight in babies regardless of tobacco use. Prenatal marijuana use was four mes higher among women who were younger, less educated, received Medicaid or WIC, were white, unmarried and lived in poverty. The study suggests that prenatal cannabis use has a detrimental impact on a baby's brain funcon starng in toddlerhood, specifically issues related to aenon deficit disorder. 88% of women who use cannabis in pregnancy also breaseed their babies.

  • Pregnant People's Perspectives on Cannabis Use During
    Pregnant people's perspectives on cannabis use during pregnancy: A systematic review and integrative mixed-methods research synthesis Meredith Vanstone1, Janelle Panday1, Anuoluwa Popoola1, Shipra Taneja1, Devon Greyson2, Sarah McDonald1, Rachael Pack3, Morgan Black1, Beth Davis1, and Elizabeth Darling1 1McMaster University 2University of Massachusetts Amherst 3Schulich School of Medicine and Dentistry March 17, 2021 Abstract Background: Cannabis use during the perinatal period is rising. Objectives: To synthesize existing knowledge on the per- spectives of pregnant people and their partners about cannabis use in pregnancy and lactation. Search strategy: We searched MEDLINE, APA PsycINFO, Cumulative Index to Nursing and Allied Health Literature, Social Science Citation Index, Social Work Abstracts, ProQuest Sociology Collection up until April 1, 2020. Selection criteria: Eligible studies were those of any methodology which included the perspectives and experiences of pregnant or lactating people and their partners on cannabis use during pregnancy or lactation, with no time or geographical limit. Data collection and analysis: We employed a convergent integrative approach to the analysis of findings from all studies, using Sandelowski's technique of \qualitizing statements" to extract and summarize relevant findings from inductive analysis. Main results: We identified 23 studies of pregnant people's views about cannabis use in pregnancy. Comparative analysis revealed that whether cannabis was studied alone or grouped with other substances resulted in significant diversity in descriptions of participant decision-making priorities and perceptions of risks and benefits. Studies combining cannabis with other substance seldom addressed perceived benefits or reasons for using cannabis. Conclusions: The way cannabis is grouped with other substances influences the design and results of research.

Martin1,2 Received: 10 February 2020 / Revised: 18 May 2020 / Accepted: 28 May 2020 © The Author(s), under exclusive licence to Springer Nature America, Inc. 2020 Abstract There is growing evidence that there is an increased use of Marijuana (cannabis) during the perinatal period. This review summarizes pertinent legislation (past and present) and the physiology and pathophysiology of cannabis use during pregnancy. The literature which involves issues concerning cannabis and pregnancy is expanding but at present has many gaps and unanswered questions. The effects on the newborn are significant and treatment recommendations including breastfeeding are presented. Also included is a description of developmental delay during the first 2 years of life in infants exposed to prenatal marijuana. In addition, this commentary discusses the increase use of the newer “synthetic” cannabinoids which have greater psychotropic activity and can cause significant harm. 1234567890();,: 1234567890();,: Introduction United States Federal Bureau of Narcotics produced litera- ture saying that marijuana was an addicting substance Throughout the world the use of marijuana for both med- which led users to narcotics addiction.

  • Cannabis, the Pregnant Woman and Her Child: Weeding out the Myths
    Journal of Perinatology (2014) 34, 417–424 & 2014 Nature America, Inc. All rights reserved 0743-8346/14 www.nature.com/jp STATE-OF-THE-ART Cannabis, the pregnant woman and her child: weeding out the myths SC Jaques1, A Kingsbury2, P Henshcke3, C Chomchai4, S Clews5, J Falconer5, ME Abdel-Latif6, JM Feller7,8 and JL Oei1,8 To review and summarise the literature reporting on cannabis use within western communities with specific reference to patterns of use, the pharmacology of its major psychoactive compounds, including placental and fetal transfer, and the impact of maternal cannabis use on pregnancy, the newborn infant and the developing child. Review of published articles, governmental guidelines and data and book chapters. Although cannabis is one of the most widely used illegal drugs, there is limited data about the prevalence of cannabis use in pregnant women, and it is likely that reported rates of exposure are significantly underestimated. With much of the available literature focusing on the impact of other illicit drugs such as opioids and stimulants, the effects of cannabis use in pregnancy on the developing fetus remain uncertain. Current evidence indicates that cannabis use both during pregnancy and lactation, may adversely affect neurodevelopment, especially during periods of critical brain growth both in the developing fetal brain and during adolescent maturation, with impacts on neuropsychiatric, behavioural and executive functioning. These reported effects may influence future adult productivity and lifetime outcomes. Despite the widespread use of cannabis by young women, there is limited information available about the impact perinatal cannabis use on the developing fetus and child, particularly the effects of cannabis use while breast feeding.

  • Cannabis R a Short Review Discussion Pape
    Cannabis r A Short Review Discussion Pape Cannabis: A Short Review Cannabis: Its Use, Functions, and Prevalence Cannabis, produced from the Cannabis sativa plant, is used in three forms: herbal cannabis, the dried leaves and flowering tops, also known as ‘cannabis,’ ganja,’ or ‘weed,’ among others; cannabis resin, the pressed secretions of the plant, known as ‘hashish’ or ‘charash;’ and cannabis oil, a mixture resulting from distillation or extraction of active ingredients of the plant.Herbal cannabis is the cannabis product used most frequently in much of the world, while cannabis resin is primarily used in Europe.Cannabis oil is less widely used, accounting for only 0.05% of cannabis seizures in 2009.1 Cannabis is produced in nearly every country worldwide, and is the most widely produced illicit drug.The highest levels of cannabis herb production – approximately 25% of global production – take place in Africa, particularly in Morocco, South Africa, Lesotho, Swaziland, Malawi, Nigeria, Ghana, Senegal, Gambia, Kenya, and Tanzania.North and South America follow, each responsible for 23% of worldwide production of cannabis herb.Indoor production of cannabis herb is rising, as there is a lower chance of detection and growers are able to harvest multiple times per year, and is concentrated in North America, Europe, and Oceana. Cannabis herb remains the most trafficked illicit drug in the world in terms of volume and geographic spread.North America accounts for 70% of global seizures, particularly concentrated in Mexico and the United States, followed by Africa (11%) and South America (10%). Cannabis resin is second to cannabis herb in terms of volume of trafficking.Afghanistan has recently emerged as a major producer of cannabis resin, overtaking Morocco in terms of volume, and cannabis has become a competitor to opium poppy as a lucrative crop for farmers.Nearly all cannabis resin seizures (95%) took place in Europe, the Middle East, Southwest Asia, and North Africa.
