I lost my job on the 20th and just now found another, but it won't start until the 8th of july. I'm broke. About the only way I can think of to make enough money to get by on until then is to donate plasma. I probably won't even get a check from the new place until the end of July (damn, just thought of that). I can't afford the time to get clean. Can I donate Plasma if I smoke weed? I know they will reject you if you tell them but do they do any tests? The plasma center here just switched over from Sera-Tec to Bio-Life. Have any of you ever donated plamsa while you had weed in your system? If I do donate and it comes back positive, will I ever be able to donate again or will my name be flagged and a "do not accept" type of thing. Thanks.
