Usually, symptoms indicating a bad cannabis trip vary due to the multiplicity of causal factors but some symptoms have been reported commonly. These symptoms include numbness especially on the face, sweating, shortness of breath, paleness, anxiety, loss of control and upset stomach which could result in vomiting. These symptoms are commonly psychological as the fear and nerves one has from realizing that he or she is high is what is responsible for them. Although it can be very uncomfortable for anyone to be on a bad trip, the individual should know that it is common and wait it out.
