Cannabis Overview
Cannabis, also known as marijuana, is a plant that contains more than 100 compounds known as cannabinoids. Some of these compounds can have psychoactive effects when consumed, which is why cannabis is often used for recreational purposes. However, cannabis has also been used for medicinal purposes and specific compounds found in cannabis (e.g., THC, CBD, CBN) are thought to have different effects and work on different receptors in the body. The two main cannabinoids in cannabis that are used medicinally are tetrahydrocannabinol (THC) and cannabidiol (CBD). THC is the psychoactive compound in cannabis, while CBD is not psychoactive. Cannabidiol (CBD) is also found in the prescription drug Epidiolex and is used to treat certain types of seizures.
Paliperidone Palmitate Overview
-
Paliperidone extended-release injections (Invega Hafyera, Invega Sustenna, Invega Trinza) are used to treat schizophrenia (a mental illness that causes disturbed or unusual thinking, loss of interest in life, and strong or inappropriate emotions). Paliperidone extended-release injection (Invega Sustenna) is also used alone or with other medications to treat schizoaffective disorder (a mental illness that causes both a loss of contact with reality and mood problems [depression or mania]). Paliperidone extended-release injection is in a class of medications called atypical antipsychotics. It works by changing the activity of certain natural substances in the brain.
