There is currently no strong evidence to suggest that CBD stunts growth in humans. Most of the available research focuses on how CBD affects the brain, nervous system, and mood, with far less known about its long-term impact on physical development especially in children and teenagers. While CBD is generally seen as non-intoxicating and low-risk, its effects on growth, hormones, and development are still being studied. For that reason, caution is advised when considering CBD for younger users.
What We Know So Far
CBD, or cannabidiol, is a compound derived from the cannabis plant. It interacts with the body’s endocannabinoid system, which plays a role in regulating sleep, appetite, immune function, mood, and even some aspects of development. While these functions are important during periods of growth, there’s no conclusive research showing that CBD directly interferes with height, bone development, or puberty.
Use in Children and Adolescents
In the UK, CBD is not routinely recommended for children unless under medical supervision. Some clinical uses such as treating severe forms of epilepsy involve controlled CBD-based medicines like Epidyolex. These are prescribed only when other treatments have failed, and the child is monitored closely. In these cases, the potential benefits outweigh the risks, and any possible impact on growth is considered a lesser concern than controlling seizures.
The Role of Hormones and the Endocrine System
Growth during adolescence is heavily influenced by hormones, particularly those regulated by the endocrine system. There is currently no evidence that CBD disrupts hormone production in a way that would impact physical development. That said, because the endocannabinoid system is involved in hormone balance, researchers are still exploring how long-term CBD use could affect puberty, growth rate, or bone density in growing bodies.
Animal Studies and Limitations
Some animal studies suggest that cannabinoids may influence bone formation or hormonal pathways, but these results don’t directly translate to humans. Most of these studies use high doses over long periods, far beyond what a typical person would use. Until more long-term human data is available, we can’t say with certainty whether CBD affects growth one way or another, which is why most experts recommend a cautious approach for younger users.
Safe Use and Professional Advice
For adults, there is no reason to believe CBD affects height or bone development. For teenagers or children, it should only be used under medical guidance, particularly when it’s part of treatment for a diagnosed condition. Parents and caregivers should always consult a healthcare professional before giving any CBD product to someone who is still growing. High-quality, THC-free products should be used if CBD is deemed appropriate.
Summary
There is no clear evidence that CBD stunts growth, but its effects on children and adolescents are not fully understood. While it is considered safe for most adults, its use in young people should be approached carefully and only under medical supervision. More research is needed to determine how, if at all, CBD influences growth and development during key life stages.
