When I worked for Bill Atkinson's sister, Dr. Kathy Atkinson, at UCR in high school, I was involved in a DMSO leak. Dr. A. was a microbiologist, but botanists worked upstairs. I guess DMSO is used a lot in botany, and they let an experiment boil over and DMSO got into the HVAC air return and then into the whole building. Smelled like garlic, and I turned bright pink. We had to evacuate. I also tasted garlic for a day or so. Nowadays you have to be 18 to get a job in a UC Lab.

You could get DMSO and ketamine at the vet supply store back then in the 80s. I heard of people ingesting acid via DMSO in that time frame, but it could have been an urban legend. It was a horse area and DMSO was used with horses to get stuff deep into their legs or something like that.
