ABSTRACT
A utilização medicinal da Cannabis sativa L., usualmente chamada de maconha, é conhecida desde tempos remotos devido a suas elevadas propriedades terapêuticas. As discussões acerca de seu uso medicinal no Brasil são urgentes, notadamente porque já há comprovação científica dos benefícios relacionados ao tratamento de diversas enfermidades. Este artigo teve como foco demonstrar que os argumentos apresentados para criminalizar a C. sativa, além de concorrerem para uma conjuntura racista e criminalizadora de classes sociais baixas, violam os princípios bioéticos da beneficência, autonomia e justiça, ao impedir que o sujeito tenha acesso a prescrições médicas adequadas e menos onerosas, a fim de proporcionar o alívio de suas dores físicas e psíquicas. Para tanto, utilizou-se da metodologia qualitativa, por meio da qual se realizou revisão bibliográfica de artigos científicos publicados em português, entre os anos de 2015 e 2020, nas bases de dados Google Scholar e Scientific Electronic Library Online, juntamente com pesquisa de resoluções da Agência Nacional de Vigilância Sanitária e do Conselho Federal de Medicina. De posse desses dados, constatou-se a necessidade de democratização no acesso à C. sativa medicinal, sendo imprescindível o fornecimento gratuito de canabidiol pelo Sistema Único de Saúde, bem como uma normatização que permita o cultivo da C. sativa para fins medicinais para a produção de medicamentos no país.
The medicinal use of Cannabis sativa L., usually called marijuana, has been known since ancient times, due to its enhanced therapeutic properties. Discussions about its medicinal use in Brazil are urgent, especially because there is already scientific proof of the benefits that it can produce in treatment of various diseases. Therefore, it is essential that there is support from the State so that access to C. sativa for medicinal purposes is universal, considering the right to health treatments as a fundamental right, provided for in the Constitution. However, the use and possession for own consumption are still criminalized. Thus, the article seeks to demonstrate that the justifications presented to criminalize this plant, in addition to contributing to a racist marginalization of low social classes, violate Bioethical precepts, by preventing patients from accessing medical prescriptions that are adequate and less costly, to provide relief from their physical and mental pain. For that, we used a qualitative methodology. A bibliographic review of scientific articles published in Portuguese, between the years 2015 and 2020, was carried out in the Google Scholar and Scientific Electronic Library Online databases. Resolutions of the Brazilian Health Regulatory Agency, as well as of the Federal Council of Medicine were also considered. With these data, this article concludes that the need for democratization in access to medicinal C. sativa is imperative, by supplying patients with CBD compounds through the Brazilian National Public Health System, and by enacting legislation that allows for the cultivation of C. sativa for medicinal purposes and for medicine production in Brazil.

Objective To assess the feasibility of the rbcL sequence of chloroplast DNA as a genetic marker to identify Cannabis sativa L. Methods The rbcL sequences in 62 Cannabis sativa L. samples, 10 Humulus lupulus samples and 10 Humulus scandens DNA samples were detected, and 96 rbcL sequences of the Cannabaceae family were downloaded from Genbank. Sequence alignment was performed by MEGA X software, the intraspecific and interspecific Kimura-2-Parameter （K2P） genetic distances were calculated, and the system clustering tree was constructed. Results The rbcL sequence length acquired by sequencing of Cannabis sativa L. and Humulus scandens were 617 bp and 649 bp, respectively, and two haplotypes of Cannabis sativa L. were observed in the samples. The BLAST similarity search results showed that the highest similarity between the sequences acquired by sequencing and Cannabis sativa L. rbcL sequences available from Genbank was 100%. The genetic distance analysis showed that the maximum intraspecific genetic distance （0.004 9） of Cannabis sativa L. was less than the minimum interspecific genetic distance （0.012 9）. The results of median-joining network and system clustering tree analysis showed that Cannabis sativa L. and other members of the Cannabaceae family were located in different branches. Conclusion The rbcL sequence could be used as a DNA barcode for identifying Cannabis sativa L., and combined with comparative analysis of the rbcL sequence and system cluster analysis could be a reliable and effective detection method for Cannabis sativa L. identification in forensic investigation.

Cannabis sativa, an annual herbaceous plant, belongs to the family Cannabaceae. It is a traditional economic crop in China, which has been applied in many fields such as medicine, food, and cosmetics. Cannabinoids are the main active ingredients of C. sativa, with analgesic, anti-inflammatory, antioxidant, sedative, and anti-vomiting activity. Here, we summarized 121 cannabinoids according to recent reports, meanwhile, analytical methods of cannabinoids were also presented. This review could lay the foundation for the quality control and further research on C. sativa.
ABSTRACT
Resumo A Cannabis sativa L. vem sendo utilizada, antes mesmo da Era Cristã, para tratar inúmeras enfermidades, mas, no início do século 20, seu uso passou a ser proibido em vários países, inclusive com escopo medicinal, por ser considerada droga ilícita. Entretanto, a necessidade de obter alternativas aos tratamentos convencionais aumentou o interesse pelo uso terapêutico dessa droga vegetal, razão por que diversos estudos passaram a ser realizados, constatando que o Canabidiol (CBD), um dos principais compostos da planta, possui grande potencial terapêutico. No Brasil, a comercialização do CBD permanece proibida, mas, a partir de 2015, o uso compassivo e importação da substância foram autorizados pelo Conselho Federal de Medicina (CFM) e pela Agência Nacional de Vigilância Sanitária (Anvisa), porém, a demanda por CBD continua sendo judicializada. Justamente neste aspecto residiu o objetivo da pesquisa interdisciplinar, que foi analisar o exterior constitutivo do problema do acesso ao referido fármaco para tratamento de doenças. Para tanto, foi realizada pesquisa documental e exploratória, utilizando a abordagem qualitativa, além da revisão bibliográfica. O estudo de caso foi realizado com os processos judiciais do Tribunal de Justiça de Pernambuco (TJ/PE) sobre o assunto, localizados a partir da inserção agrupada das palavras-chave "fornecimento" e "Canabidiol" no campo "jurisprudência" do sítio virtual desse Tribunal. Como resultado, constatou-se que os sujeitos que ingressam com ação judicial atendem aos requisitos exigidos pelos órgãos reguladores, o que permite concluir que a negativa administrativa de fornecimento do medicamento pelo estado de Pernambuco caracteriza violação ao direito à saúde deles.
Abstract Cannabis sativa L. has been used since before the Christian Era to treat numerous diseases, but in the early 20th century, its use has been banned in several countries, including for medicinal purposes, for being considered illicit drug. However, the need to obtain alternatives to conventional treatments increased the interest for the therapeutic use of this plant, reason why several studies have been carried out, which verified that Cannabidiol (CBD), one of the main compounds of the plant, has great therapeutic potential. In Brazil, its internal commercialization is prohibited, but since 2015 the compassionate use and importation of the substance has been authorized by the Federal Council of Medicine (CFM) and by the National Health Surveillance Agency (Anvisa); however, the demand for CBD continues to be judicialized. The objective of this interdisciplinary research was precisely in this aspect, which was to analyze the constitutive exterior of the problem of access to the referred drug. For that, a documentary and exploratory research was performed, using the qualitative approach, in addition to the bibliographic review. The case study was carried out with the Judicial Processes of the Court of Justice of Pernambuco (TJ/PE) on the subject, located from the grouped insertion of the keywords "supply" and "Cannabidiol" in the field "jurisprudence" of the virtual site of this Court. As a result, it was found that individuals who file a lawsuit meet the requirements of regulatory agencies, which allows to conclude that the administrative refusal to provide the drug by the state of Pernambuco characterizes violation of their right to health.

As the most widely used narcotics in the world, Cannabis sativa is also regarded as one of the earliest drugs that used by humans. Exploring the origin and early dissemination of C. sativa as medicine can shed light on the safe and effective usages of marijuana-derived drugs and the scientific development of the new medicinal value of C. sativa, which are of important social and ethical significances. Bencao archaeology and herbal textual research are dual evidence for herbalism studies. By integrating the evidence from archaeological remains and references of the early civilizations of the world, this study revealed the medicinal origin of C. sativa and its early expansion, and then in the context of the human cultural background, explored the factors driving the original spread of C. sativa as a medicine in Eurasia. The results showed that the medicinal origin of C. sativa was likely rooted in the original utilization of its psychoactive substance by ancient humans in traditional rituals, by inhaling the smoke from the burning of the psychoactive substance of C. sativa, which was likely to be the original mode of the use of C. sativa as a medicine. Also, based on the existing archaeological remains, the Yamnaya populations from early East Europe (3000 BC) were supposed to be the earliest human beings employing C. sativa for medical purposes. After originating from East Europe, medicinal C. sativa probably dispersed into the West Asia and Central Asia. Afterwards, it has spread into South Asia southward and into North Asia and East Asia northward with the Central Asia as the diffusion center. Indo-European populations were supposed to be the main human beings using the psychoactive substance of C. sativa, and there was a high degree of similarity between the routes of the expansion of the Indo-European language family and the course of early spread of C. sativa. In terms of the above two understandings, we suggested that the dispersal of the Indo-European populations probably have driven the early spread of C. sativa as medicine across Eurasia.
ABSTRACT
Objective To disclose the inter-species differences among Papaver somniferum L, Papaver rhoeas L and Cannabis sativa L using AFLP analysis. MethodsThe root, stem, foliage, flower, seed of Papaver somniferum L, foliage of Papaver rhoeas L and Cannabis sativa L were collected respectively. DNA was isolated with AxyPrep Kit, and double-digested by EcoR I and Mse I, then oligonucleotide adapters were ligated. After Pre-amplification, selective amplification was performed using 6 pairs of fluorescent primer. The DNA fragments were analyzed using a CEQ 8000 DNA Fragment Analyzer. Results27 to 46, 5 to 20 and 4 to 31 pieces of amplified products were detected from Papaver somniferum L, Cannabis sativa L and Papaver rhoeas L respectively, and significant difference was observed among these three groups of products. The identical species-specific peaks were identified from root, stem, leaf, flower and seed DNA from the same Papaver somniferum L. ConclusionThe diacritical results from Papaver somniferum L, Papaver rhoeas L and Cannabis sativa L, as well as the identical results of different parts from the same plant demonstrated that AFLP analysis could be used possibly to determine the species origin of unknown plants samples.
