I'd just like to firstly point out that I have been using spice gold / diamond for at least 3 months now and have grown up a fairly good resistance. Although on Saturday night, after sparking up one of my usual J's (little bit bigger than usual to be fair), I was having a great buzz... Until my heart starting pulsating rapidly, then faster, and once more even faster, I couldn't breath, nor stand up. My heart beat was extremely fast, I'm talking 3 - 4 beats a second from what I remember. I was taken to the hospital (A&E) straight away. My heart was then hooked up and monitored, while doctors where injecting me with a drug, that is meant to slow my heart beat down. I then had a blood test and xray, although the results were sent of to London (UK), they could not identify the substance and I quote " The substance was found to be 5 times stronger than cannabis). I had turned round only to see my heart beat was peaking 160 BPM, which is pretty damn scary, considering 70 to 80 is standard for an adult male. My legs were uncontrolably shaking, though my this point I was in such a state of shock, I asked where I could be put out for a while, although I wasn't allowed. After 3 hours of agony and fright, my BPM was at 120 - 130, and I could clearly tell the doctors were worried by this time, just from the look on thier face, staring at the monitor. I was told I might need to be put out and then have be "shocked" so that my heart beat would go back to normal, as my heart beat was inregular and seemed to be causing attention from other staff. Around about 5 hours after, I was injected once again and thankfully my BPM went down to 100 - 110 and the doctors decided to let me "sweat it out", so it would seem, though I was greatfull, I am not sure what kind of drastic measures they might have taken if my BPM didn't drop! I had no sleep at all, and after a hellish night, with an old man talking to himself all night (in the ward next to mine), I felt much better in the morning, although I could still feel my heart had been straigned. This happend last night, and I am still feeling a little weak right now. PLEASE IF YOUR GOING TO TAKE SPICE, MAKE SURE ITS IN MODERATION AND NOT DIAMOND, I WAS SOMKING IF FOR AROUND 3 MONTHS AND I HAVE NEVER HAD ANYTHING LIKE THIS BEFORE. The expierience has put me off for life now, I never want to go through the same exp. again. Best bet, is to stay away from this stuff (I have no alergies or medical history), if it had this effect on me I am sure others could suffer the same!
