Scientists offer a strong counter-position to the belief that cannabis causes psychosis, pointing out the difference between correlation and causation. They argue that smoke exposure from any source (including cigarettes) could explain the reported link between cannabis and psychosis.
Many people use cannabis to treat insomnia, as THC has proven effects. What about CBD? There are no clear, incontrovertible studies, and effects differ by the user, but there are promising results. More noticeably, certain terpenes have been shown to be quite effective, for example, Myrcene. http://bit.ly/2F9PXUp
Benjamin Caplan, MDTreating insomnia with cannabis
In a placebo-controlled study of a cannabis oral spray in patients with ADHD, there was no significant improvement in cognitive performance, but there was a significant improvement in hyperactivity and impulsivity.
In a study of 72 psychiatric patients given CBD in capsule form, researchers found that cannabidiol successfully decreased anxiety and improved sleep over the course of three months.
Study finds that, for patients already taking antidepressants, activating and/or prohibiting the CB1 receptor in the brain might make those antidepressants more effective.
In a study that excluded cannabis users, researchers found that alcohol hangovers significantly impair both executive function (paying attention, regulating emotions, etc.) and prospective memory (remembering future plans).
Preferences for Medical Marijuana over Prescription Medications Among Persons Living with Chronic Conditions: Alternative, Complementary, and Tapering Uses
In a survey of 30 patients using medical cannabis for a range of illnesses, including Rheumatoid Arthritis, cancer, Hepatitis C, PTSD, and more, patients reported an array of benefits from their cannabis use. Patients successfully used cannabis as an alternative to prescription medication, as a complementary agent with traditional prescription medicines, and to gradually help halt the use of some prescription medications. Benefits described by participants included the effects of cannabis lasting longer than that of opioids, lower risk of addiction, fewer side-effects. Patients also saw their sleep, anxiety, appetite, and adverse reactions improve with the use of medical cannabis. Larger, more controlled studies may suggest cannabis more affirmatively as an alternative or complementary therapy with prescription medications.
