IF YOU KNOW ANYTHING ON THIS TOPIC PLEASE SHARE! Im not sure if this is everywhere or just some places but there is a few plasma( I guess you might call clinics) in Knoxville, TN U.S.A. They take plasma from your blood to help others who need it, this usually takes an hour to donate. The thing is they just let anybody On the streets come in and donate. Seems great right? WRONG! People flock to one of the major homeless hotspots in America and Knoxville is huge haven for the homeless. Living amongst them, I learned exactly how it worked. One man had huge holes in his arms from donating plasma for years! Yuck! My fiancé went to donate several times while we were trying to get back on our feet. We were living in a hotel thus had an abundance of neighbors. Knowing some of them were on drugs and some even shooting dope they went to get their free card with free money they got from "donating" plasma. 50.00$ the first 2 times you donate and 25.00$ every time after. They weren't drug tested and in one incident a man didn't meet the weight requirements and filled his coat pockets with rocks, he got kicked out for this. I thought to myself "what happens when someone receives your plasma Can they get diseases from that?" Well folks please if you have any medical knowledge about what happens if anything in this particular case??? As always thanks for taking the time to read!
