Sativas come from a temperate climate near the equator, while the Indica likely originated around present-day Afghanistan, specifically near the Hindu Kush area. The climate and weather conditions there are harsh — this is likely why they have a thicker protective coat of resin than the Sativa strains.

Study: Marijuana Genetics Often Mislabeled

Strains of cannabis sativa or cannabis indica possess relatively few significant genetic differences and are often mislabeled by breeders, according to an evaluation of marijuana taxonomy published online last week in the journal PLOS ONE.

Investigators from the University of Manitoba, the University of British Columbia, and Dalhousie University in Nova Scotia evaluated the genetic structure of diverse range of commonly cultivated marijuana and industrial hemp samples.

Study: Sleep-Disturbed Patients Find Relief from Cannabis Use

sleepSleep-disturbed patients find relief from consuming cannabis, according to a new study published in the journal Addictive Behaviours, and published online by the National Institute of Health.

For the study, researchers at the University of California, the National Center for PTSD and John Hopkins University examined 163 adults who were recruited after purchasing medical cannabis for a physical or mental health condition at a legal dispensary in California. They provided self-report of “(a) whether cannabis use was intended to help with sleep problems (e.g. insomnia, nightmares), (b) sleep quality (PSQI), (c) cannabis use (including preferred type), and (d) symptoms of DSM-5 cannabis dependence.”
