While cannabis is often used for alleviating anxiety, certain research has shown that cannabis use can produce feelings of anxiety, paranoia, and panic. In this recent review paper, researchers found that acute doses of CBD reduced anxiety in humans, while THC may be associated with causing anxiety. These anxiety causing effects of THC were greater among infrequent or non-users compared to frequent users. When used with CBD, these effects were decreased. However, animal studies have also shown that there may be potential for THC to reduce anxiety, if given at the right dose and when co-administered with CBD.
