yeah, weed can cause some anxiety or paranoia when you get high, mostly if you're not good at handling it and have underlying issues of stress (as stated above). but guess what, the prescription shit doctors pump into us is no better and quite often worse. when I went on paxil, which is "non-addictive" btw, it was like I was on crack for the first few days. then I went numb and felt empty, then after a month it stopped doing anything. so I went off our non-addictive friend and for 3 days was so stressed and anxious I could barely eat or communicate with anybody without snapping their heads off. weed has done so much more for me than any of the painkillers for my nerve damage or anti-depressants for my anxiety/depression. it simply took a few weeks to adjust and figure out my safe dosage.
