Ive been smoking non stop for about 2 years because of daily stress in my life and marijuan WAS helping but a few months back it caused me to have an anxiety attack, i was just sitting, relaxing and smoking and whamm! I started to get real scared, shake, sweat and couldnt calm down. I sat like that for about 6 hours and when it didnt go away I dragged myself to the ER. My blood pressure was very high and I was trembling an my palms were sweating like crazy, I couldnt focus on anything and terrified! The doctor though it was my thyroid or some adrenal gland that was making me race, I didnt tell him about my addiction fearing some trouble so he said I had a Anxiety Attack caused by stress!!! I was given Prozac and Xanex. I went home took the pills and wanted to smoke a little to see if it would relax me....Wrong! It made my heart race all over again but it went away faster than last time. Why did this happen? Because I abused marijuana too much daily. I took the pill for a month and felt better, since then I still smoke but take it easy, sometimes my heart srtats to race and I have to take a break....Anyone else?????????
