Mr. Stoner: "I don't need to! See, my friend gives me marijuana, and if I smoke it several times a day than I don't have seizures. Hey, can you give me some while I'm here? He's not answering his phone."
Dr. Grumpy: "Local Hospital doesn't keep marijuana in the pharmacy and..."
Mr. Stoner: "Well, I'm not going to take any of your pills!"
Several hours later, at the nursing station...
Dr. Grumpy: "All right, here's some orders on the new admission. Hey, has Mr. Stoner had his EEG yet?"
Nurse: "He left AMA*. Didn't anyone tell you?"
Dr. Grumpy: "No. When did this happen?"
Nurse: "After you told him the hospital wasn't going to give him marijuana. He snuck out of his room and went down to ER, trying to find a patient there who could sell him some. When security came after him he ran out of the building and didn't come back."
