While kava is not considered to be as addictive as other drugs, it is possible to develop a dependence on it if used in high doses or for prolonged periods. Some people who use kava may experience withdrawal symptoms such as anxiety, agitation, insomnia, and restlessness if they suddenly stop using it. However, the risk of addiction or dependence on kava is generally considered to be low when it is used appropriately and in moderation. It is always advisable to consult with a healthcare provider before using any herbal supplement, including kava.
