It can be the most potent of the main cannabis products because of its high level of psychoactive compound per volume, which can vary depending on the plant’s mix of essential oils and psychoactive compounds. Hash oil is a resinous matrix of cannabinoids obtained from the cannabis plant by solvent extraction, formed into a hardened or viscous mass.

• There is «insufficient» evidence supporting the use of cannabis or cannabinoids for most medical purposes, a new review has concluded.
• The leaves have a peculiar and diagnostic venation pattern (which varies slightly among varieties) that allows for easy identification of Cannabis leaves from unrelated species with similar leaves.
• Furthermore, the rise of craft cannabis growers in Canada should ensure quality, experimentation/research, and diversification of strains among private-sector producers.

A limited number of studies have examined the effects of cannabis smoking on the respiratory system. Cannabinoid hyperemesis syndrome (CHS) is a severe condition seen in some chronic cannabis users where they have repeated bouts of uncontrollable vomiting for 24–48 hours.Four cases of death have been reported as a result of CHS.

An investigation of genetic, morphological, and chemotaxonomic variation among 157 Cannabis accessions of known geographic origin, including fiber, drug, and feral populations showed cannabinoid variation in Cannabis germplasm. Several studies of random amplified polymorphic DNA (RAPD) and other types of genetic markers have been conducted on drug and fiber strains of Cannabis, primarily for plant breeding and forensic purposes. This taxonomic interpretation was embraced by Cannabis aficionados who commonly distinguish narrow-leafed «sativa» strains from wide-leafed «indica» strains. Sativa subspecies into 13 varieties, including four distinct groups within subspecies culta.
