Cannabidiol (CBD), The Component In Cannabis Often Used For Therapeutic Treatments, is Increasingly Being Used During Pregnancy As A Means of Managing Schmpts Such AS Nausea, Anxiety and Sleep. THOUGH THE PUBLIC PERCEPTION IS THAT CBD – PARTICULARY WHEN CONSUMED ORALLY – SAFER AND HELPFUL FOR SYMMPTOM MANAGEMENT, Little is Known About The Impact of CBD on Pregnacy.
The New Study from McMaster University Researchers Fills That Gap in Knowledge and Has UNCOVED POTENTIAL RISKS, Including Impaired Fetal Growth, Associated with the Use of Both Tetrahydrocannabinol (THC) , During Pregnancy.
THE RESEARCH, PUBLISHED IN Ebiomedicine On FEB. 5, 2025, Found Oral Cannabis Use from Early to Mid-Pregnance Was Associated with Impaired Fetal Growth and Changes in the Placenta, As Wells Changes in Aggression, Activity Levels and Learning Ability in Offspering.
“The Use of Cannabis During Pregnancy is rising in canada. Most Previas Studies Focus on Exposure to Cannabis Smoke or Just The Psychoactive Component of Cannabis (THC) chie, who led the Study While Completing Her Master’s Degree in the Medical Sciences Program at McMaster University and with the McMaster Immunology Research Center.
“However, Consumption Cannabis Orally Or Only Using other cannabis ingredients like CBD, is often perceived as safer despite this lack of evidence. OUR STUDY IS SHEDDING LIGHT (ON THE FACT) THAT’S POSSIBILITY THAT CBD MIGHT ALSO BERMFUL IN THE PREGNATE. “
Cannabis Use May Impact Growth and Behavior
The Group of Scientists Led by Ritchie and Ali Ashkar, Professor at McMaster’s Department of Medicine, Drive the Research By Administering Cannabis Oil to Mouse Models and FolloWed The Development of the Fetuses During Pregnancy and Post-Birth.
The Researchers Found That Both Thc and CBD Impaired Fetal Growth, Causing Fetuses to Be Small when Compred to Mice That Did Not Receive Cannabis. Addihthanly, They Found That Both Thc and CBD Impact Development of the Blood Vessels That Supply The Placenta and Therefore The Baby With Nutrients.
“We Did See That Both Thc and Cbd Can Disrupt a Special Type of Imamune Cell Called A Uterine Nk Cell That is crucial in Normal Development of the Placenta. We Also Saw Poor Development of the Arteries That Help Supply Blood to the Placenta. We ‘ Re THINKING THIS IS WHAT IS POSSIBLY DISRUPING THE NUTRIENT AND OXYGEN DELIVERY TO THE BABY AND CONTRIBUTING TO THE INTRAUETERINE GROWTH RESTRICTION, “SAYS ASHKAR.
When Observing the Behavior of the Babies Post-Birth, Researchers Found Changes in Their Aggression, Activity Levels and Even Learning Ability.
“Oral Use Of Thc And CBD During the Pregnancy Not Only Disrupts Growth of the Baby But Sems to Long-Term Consequences As the Babies Were Found to Have Changes in Their Behavior Later in Life,” Says Ritchie.
Ritchie says more Research is Needed to Better Understand the Impacts of Cannabis In Humans During Pregnancy, But Says This Study Shows The Possibly of It Being Dangerous or Harmful.
