Depending on cannabinoid profile, intake, strength it can help with or potentiate panic attacks (which sometimes start with omg I comitted a crime. What if someone finds out? Or by the unfamiliarity of the feeling - was my drug laced with something?) For the exact reason it should be legal, so people know what they take. As a sufferer of panic attacks I can attest that cannabis had been a life saver at times, although I don't medicate (with cannabis nor prescription drugs) at all now.
