I Got Really Fed Up With Having Daily Headaches, Ive Had The Works Mri's Ct's And Tried All Types Of Prescribed Meds Which I Am Not A Big Fan Of Pills.a Friend Of Mine Gave Me A Joint And Said It Would Help, So I Tried About 3/4 Of It, 10 Minutes Later I Was Having The Worst Anxiety Attack In My Life, I Felt Very Faint, My Heart Wouldnt Slow Down, Tingley Hands, Dry Mouth Ect. I Made It To My Local Er And Told Them What I Tried. Man I Am Still Scared!!! They Checked My Heart And Every Thing And Told Me I Wasnt Having A Heart Attack Or Stroke It Was Anxiety From The Drug,they give me an injection of benz something. They Said It Wasnt Laced With Anything.that Was The First And The Last For That Crap. Is This Normal For This To Happen?? how long will these anxious feelings stick around ,its been over 20 hours?
