You can develop an anxiety disorder from using cannabis. Cannabis, or "weed," can induce severe panic attacks, and it would be difficult to tell the difference from panic disorder. The difference between panic attacks from cannabis versus panic attacks from panic disorder is that the panic attacks from cannabis use can stop once you quit using cannabis. The panic attacks from panic disorder stop only with treatment with therapy and sometimes with prescription medication.
There are some people who will continue to have panic attacks when they discontinue their use of cannabis. In this situation, the cannabis has triggered a panic disorder, and now you have to treat it like you would for panic disorder.
