As with most therapies, CBD use may entail some risks. It may interact with supplements and other drugs. Most CBD products do not have FDA approval, which also means they have not undergone thorough tests.
It is not possible to know if a product:
- is safe and effective for everyone to use
- has the properties or contents stated on the packaging
Anyone who is using CBD – whether as a prescription drug or in other forms — should first speak to a doctor.
Possible adverse effects include:
- interactions with other drugs and alcohol
- changes in alertness, which can make driving dangerous
- gastrointestinal problems and loss of appetite
- mood changes, including irritability and irritation
- a reduction in fertility for males
Future research may prove CBD effective in treating various conditions. For now, however, the FDA urges people not to depend on CBD as an alternative to conventional medical care.
