Have you heard of a medicine that comes from cannabis but doesn't get you “high”? That's cannabidiol, or simply CBD — a substance that has been revolutionizing healthcare in Brazil and around the world.
But what is CBD exactly? How does it work in the body? And why are so many people — from doctors to patients, scientists, athletes, and even celebrities — keeping an eye on this compound from the cannabis plant?
What is cannabidiol (CBD)?
Cannabidiol is one of over 100 phytocannabinoids found in the Cannabis sativa plant. Unlike THC (tetrahydrocannabinol) — the compound best known for causing psychoactive effects — CBD does not alter perception or induce the feeling of being “high.”
On the contrary: CBD has been attracting attention precisely for its therapeutic potential, with actions that may include anxiolytic, anti-inflammatory, anticonvulsant, and neuroprotective effects.
Why has CBD become so popular?
The increased interest in CBD has several reasons:
- Growing scientific evidence about its use in conditions such as epilepsy, anxiety, chronic pain, autism, and insomnia.
- Authorization by Anvisa for cannabis-based products for medicinal use in Brazil.
- Search for natural alternatives and less invasive options to traditional medications.
- Reduced stigma: more and more people, including doctors, are openly discussing the use of CBD.
On the Sechat portal, you will find extensive coverage of these advancements, including interviews with experts, regulatory analyses, scientific studies, and real patient stories.
How does CBD act in the human body?
CBD interacts with the Endocannabinoid System, a biological system present in all humans and responsible for regulating functions such as sleep, pain, mood, and immunity.
Unlike medications that act in a specific way, CBD helps the body restore natural balance (homeostasis), potentially improving well-being more broadly.
What do the studies say?
The Sechat portal closely follows the main research on cannabidiol in Brazil and abroad. Clinical studies published in universities such as USP, Unifesp, and Harvard point to promising results, especially in the treatment of refractory epilepsy, autism spectrum disorders, and neuropathic pain. Check out the list of diseases treatable with cannabis.
Furthermore, there is a growing interest from the pharmaceutical industry, advancements in legislation, and the emergence of new formulations — such as oils, capsules, and sprays — based on CBD.
Is CBD legal in Brazil?
Yes, since 2015 Anvisa has allowed the importation of CBD products for personal use with a medical prescription. Since then, the landscape has evolved, and there are already domestic products authorized by the agency, available in pharmacies with a medical prescription. In 2025, Anvisa is reviewing RDC 327.
Access to medicinal cannabis in Brazil can also be obtained with a prescription from a doctor or dentist through RDC 660, which allows the importation of plant-based products. Additionally, legally authorized patient associations are a legitimate and growing avenue for obtaining artisanal extracts, offering a safe and affordable alternative for various treatments. See the list of associations.
In fact, Sechat itself has published several explanatory guides on how to legally import CBD, which doctors are prescribing it, and which products are available.
Is all CBD the same? Stay alert!
It is essential to consult a specialist doctor and seek products with traceable origins, good manufacturing practices, and that are regulated. Sechat, a reference in content about medicinal cannabis, provides safe and reliable guidance for those looking to start a CBD treatment. On Sechat, you will also find a list of prescribing doctors of medicinal cannabis.
