Cannabis (/ˈkænəbɪs/) is a genus of flowering plants in the family Cannabaceae. The number of species within the genus is disputed. Three species may be recognized: Cannabis sativa, C. indica, and C. ruderalis. Alternatively, C. ruderalis may be included within C. sativa, all three may be treated as subspecies of C. sativa, or C. sativa may be accepted as a single undivided species. The genus is widely accepted as being indigenous to and originating from Asia.
The Cannabis Act (C-45) of June, 2018 paved the way for the legalization of cannabis in Canada on 17 October 2018. Police and prosecution services in all Canadian jurisdictions are currently capable of pursuing criminal charges for cannabis marketing without a licence issued by Health Canada. The Supreme Court of Canada has held that the federal Parliament has the power to criminalize the possession of cannabis and that doing so does not infringe upon the Canadian Charter of Rights and Freedoms. The Ontario Court of Appeal and the Superior Court of Ontario have, however, held that the absence of a statutory provision for medical marijuana is unconstitutional, and to that extent the federal law is of no force and/or effect if a prescription is obtained. The recreational use of cannabis has been legalized by the federal government, and took effect on 17 October 2018.
Since 1997, public opinion polls have found that an increasing majority of Canadians agree with the statement, "Smoking marijuana should not be a criminal offence". A June 2016 national poll conducted by Nanos Research showed that 7 in 10 Canadians were in favour of legalization. (Full article...)
Joint is a slang term for a cigarette rolled using cannabis. Rolling papers are the most common rolling medium in industrialized countries; however, brown paper, cigarettes with the tobacco removed, beedis with the tobacco removed, tracing paper, ATM receipts and newspaper are commonly used in some developing countries, and by poorer smokers in first world countries. Modern papers are now made in a range of sizes from a wide variety of materials including rice, hemp, and flax, and are also available in flavored varieties. A joint can vary in size, typically containing between 0.25 to 1 grams net weight of cannabis (joints have been rolled with 2 or more pounds but this is not a common practice) (depending on whether tobacco is used in the rolling process).

I have always loved marijuana. It has been a source of joy and comfort to me for many years. And I still think of it as a basic staple of life, along with beer and ice and grapefruits - and millions of Americans agree with me.
