people have died from snorting lines of lsd when they thought it was coke.
not exactly...
"An opportunity arose to study the effects of a massive dose of LSD when a white powder was distributed at a party to guests who assumed it was cocaine. Eight patients were seen within 15 minutes of inhaling "milligram amounts" of pure LSD (verified in later police analysis of the powder). Five were comatose when first seen and were admitted to the hospital. Two patients walked in themselves and left after spending several hours in the emergency room. Symptoms included vomiting, elevated temperatures, and mild internal bleeding. LSD was detected in the blood or stomach contents of all the patients, in amounts ranging from 2.1 to 2.6 ng/ml (blood) and 1000 to 7000 micrograms/100ml (stomach contents). With supportive care, the patients recovered quickly. Those hospitalized were able to converse within four to five hours, and they were normal within twelve hours. No psychologic or physical ill effects were noted in a year of follow-up examinations of five patients. Most of the five continued to use LSD."
