I knew this crackhead who was a temp worker on a job site doing some steel work, rebar, forms, concrete, etc. Those real hard and dangerous labor jobs bring in some drug addicts or drunks that work hard and party hard.

Anyways, that guy used to donate plasma 3 days a week for extra alcohol and drug money. I think there were some regulations governing how frequently you could donate plasma, since those fuckers would do it every day if they could and totally deplete themselves to death.

Something about plasma was so profitable that clinics were setup to pay you to milk it out of ya over the course of a few hours. And of course these clinics target the working poor for their plasma and are picky about which applicants they approve. I think it was typically $60-$80 per donation. So a crackhead could make about $200 extra in drug money for just having tubes hooked up to them for a few hours.
