Marajana is a drug that can reduce anxiety. But it comes with it own side affects just as "pills" do. Marajana can actually cause whats called "rebound" anxiety. Not really considered withdrawl but the chemical THC that is naturally in Marajana stays in your system for several days and as it is matabilized by the body it causes anxiety like symptoms (increased heart rate and increased physical sensation) . So a joint smoked today will actually cause anxiety like symptoms in a few days. And thus the cycle continues as you smoke your next joint. Long term regular use of marajana has been found to increase symptoms of depression. So as with any drug....use with caution.
