question: My husband has stage 4 metastatic cancer. 3 tumors on his liver and 2 unknown nodules in his right lung. He has used meth for a long time, shooting it up and smoking it. He was clean for over a year then got his diagnosis in Sept. He is on chemo and is using again. Not all the time. About 4 times I know of. I do not do drugs. How bad is this? I cant pay. Sorry.
