When I was REALLY broke, the hubby and I would give blood. Turned out that the cute little gal doing the blood collecting lived a couple of blocks from us and was a head, too! Bobbie had the nicest touch with the needle. Got to be friends with her and her hubby, Van. (If you two are reading this, give me a yell!) About the only problem that could occur is if some poor soul was allergic to cannabis.- Granny:hippy:
