Well, since you asked... I have previous symptoms of three blood transfusions due to blood loss from bleeding ulcers, fundeplication lathroscopic surgery of the lower esophegeal sphincter muscle, apnea and depression. I have used pot off and on for my life and most consistently in 2011 after my 2nd transfusion. I saw my stats stay stable during the next 4 years of increased consistency in my use. I had to lie to my family so I could take care of my body. I had to stop this past November and 3 months later my hgb dropped from 12 to 6 and I had to have my 3rd transfusion. Since I left the hospital with 9hgb and got a prescription for a cannibis vaper oil pen. Within 5 weeks my hgb was up to 13.5 and four weeks later up to 16 ( a number I have never seen) 1st question is there now better scientific proof with the endocannabinoid system and my gerd issues? 2nd question does my stats indicated only by change in pot create a possible explanation for the recent crash?
