Repense is a communication campaign created to encourage debate and reflection on the medical use of marijuana in Brazil. The campaign began in March 2014 with the release of the short film ILEGAL (see the film) and a capture on the site of crowding Catarse. The donations of 362 people were used to produce this site, booklets, t-shirts, stickers and mugs. All the material was created to give visibility to the subject and to offer clear and reliable information on the subject. The therapeutic use of Cannabis sativa is a complex theme, but at the same time essential and urgent. We need to peel this pineapple. You can support the Repense campaign by posting this, enjoying and sharing our pages on Facebook and Youtube. And, more importantly, you can help change by talking to your friends and relatives about the medical potential of marijuana.

How to import?

The production, purchase and sale of marijuana are prohibited in Brazil, but current legislation provides that the State may authorize the cultivation for medicinal purposes. Despite this, the National Health Surveillance Agency (Anvisa) does not have a regulation that guides the citizens on how to obtain this authorization. Therefore, the only legal alternative to obtaining marijuana or derivatives for medical use is to import these products.

Currently, it is possible to purchase medical marijuana from abroad by making an “exceptional import request for personal use”. Check below the instructions and document templates needed to make this request, provided by Anvisa:

The importation of medicines subject to special control without registration in the country by natural person is possible by means of exceptional request of importation for personal use. If this formal request is made, Anvisa will analyze the possibility of authorizing the acquisition exceptionally. To initiate an exceptional import request for personal use, a request must be sent to the Office of the Chief Executive Officer (GADIP):

Office of the Chief Executive Officer (GADIP)

National Agency for Sanitary Surveillance (ANVISA)

Industry and Supply Sector

What is vaporizing?

Inhale the vapors produced by heating the grass, at a lower temperature than the combustion, with the help of vaporizing equipment. This procedure releases cannabinoids of medicinal effect, without producing smoke and its toxic components.

What are the side effects?

Products with THC or synthetic substances that mimic their effects can cause marijuana-like effects: pleasure and relaxation, dizziness, loss of motor coordination, sleep, difficulty concentrating, and increased appetite. Symptoms are temporary and may or may not appear depending on the dose and sensitivity of the patient. In the case of Sativex , only 12% of patients give up medication because of side effects.


Regular use of marijuana can lead to dependence, respiratory and memory problems, and its chronic use is associated with a higher incidence of schizophrenia. The contraindications should be analyzed according to the case of each patient. Talk to your doctor.
