A welcoming space

You don't need to arrive with all the answers.

Questions, fears and hope often arrive together, sometimes after years of trying other paths. All of it is welcome in the consultation.

I also work with family members and caregivers of children, older adults and people with neurological conditions.

“I'm afraid of being judged.”

Here, medical cannabis is treated as medicine: seriously, confidentially and with respect for your story.

Learn about my approach

“I'm not sure it's allowed.”

It is. Prescriptions and access follow the rules of Anvisa, Brazil's health regulatory agency, and I explain each step clearly.

Understand the process

“I've already tried everything.”

Many patients arrive feeling the same way. The assessment considers your whole history before any decision is made.

“What about side effects?”

Treatment starts with low doses and gradual adjustments, always with close follow-up.

“More than prescribing, my purpose is to understand, guide and care.”

Who will care for you

Medicine that looks beyond the symptoms.

Born in Anápolis, in the state of Goiás, I built my career in primary care, urgent and emergency care, intensive care and air medical transport, places where you learn to listen quickly and decide responsibly.

My interest in medical cannabis began in 2013, in Buenos Aires, and has since grown into ongoing study, constant learning and individualized care for each patient.

Frequently asked questions

Questions everyone asks.

And it's perfectly fine to ask. If yours isn't here, the team will answer on WhatsApp.

See all questions
Is medical cannabis treatment legal in Brazil?
Yes. The medical use of cannabis-based products is regulated by Anvisa, Brazil's health regulatory agency, and is permitted with a medical prescription. The main ways to access these products are buying them at pharmacies (RDC 327/2019), importing them as an individual (RDC 660/2022) and through patient associations. Without a prescription, use is not covered by health regulations.
Do I need authorization from Anvisa to use it?
It depends on the route you choose. To import the product, you need to register with Anvisa through the gov.br portal, using your medical prescription. To buy it at a pharmacy, all you need is the prescription along with the special prescription form (notificação de receita) required for that product. During your consultation, you'll be guided through the steps that apply to your case.
Can I travel with the product?
When traveling within Brazil, it's best to carry the product in its original packaging, together with your prescription and your proof of purchase or import authorization document. For international travel, the rules vary a great deal from country to country and should be checked well in advance.
Can the treatment cause a positive result on drug tests or anti-doping tests?
Products that contain THC, including full-spectrum products with small amounts, can lead to a positive result on drug tests, such as those required for some categories of Brazilian driver's license (CNH). In sports, THC is banned in competition, while isolated CBD is not on the World Anti-Doping Agency's prohibited list; even so, CBD products may contain traces of THC. If this matters to you, mention it during your consultation: the choice of product takes it into account.
How soon will I notice the effects?
It varies from person to person and from condition to condition. Some people notice changes in the first few days; for others, the response appears over several weeks, as the dose is gradually adjusted. That's why the treatment is assessed through ongoing follow-up, and the Wellbeing Diary helps a lot with this process.
