CBD and THC have many of the same medical benefits. They can provide relief from several of the same conditions. However, CBD doesn’t cause the euphoric effects that occur with THC. Some people may prefer to use CBD because of the lack of this side effect.
In June 2018, the U.S. Food and Drug Administration approved Epidiolex, the first prescription medication to contain CBD. It’s used to treat rare, difficult-to-control forms of epilepsy.
CBD is used to help with other various conditions, such as:
- psychosis or mental disorders
- inflammatory bowel disease
THC is used to help with conditions such as:
- muscle spasticity
- low appetite
CBD is well tolerated, even in large doses. Research suggests any side effects that do occur with CBD use are likely the result of drug-to-drug interactions between CBD and other medications you may be taking.
THC causes temporary side effects, such as:
- increased heart rate
- coordination problems
- dry mouth
- red eyes
- slower reaction times
- memory loss
These side effects are part of the compound’s psychoactive properties.
Neither compound is fatal. However, high THC use may be connected to long-term negative psychiatric effects. This is especially true for adolescents who consume large amounts of THC. Use of the compound increases the risk for some psychiatric disorders, such as schizophrenia.
