pot makes depression and anxiety worse it is not used to prevent it is used to agrivate the illness..it is not used for ptsd other than making the central nervous system numb it interferes with the communication to the brain when the pot deadens the nervous system and does to the brain what alcohol does. to use pot only makes it worse. how could anyone in the health dept even consider using pot to make someone depressed or anxious better when everyone knows pot can agrivate anxiety. or panic attacks...you guys need to look for another job if you cant figure this out
