I think I was infected with a serious life threatening disease through the use of a marijuana pipe. How do I prove this and can I sue for damages?
I think it would be impossible to prove you were infected by this method, even if you could sue for damages it would be almost impossible. The use of drugs is known to be hazardous and anyone taking any drug would assume there is some risk involved. The act itself (depending on the state/county) you live in could see this as a criminal act and you would be confessing to it in open court if you sued (it would be a legal declaration) and so could land you in trouble (you would also be informing on the other parties present).
