    Chemists from 1925 in 1960… I don’t remember always having this much cancer… Or reduced lung function.

      I perceived an uninterrupted stream of fantastic pictures, extraordinary shapes with intense, kaleidoscopic play of colors. After some two hours this condition faded away.

      This was, altogether, a remarkable experience - both in its sudden onset and its extraordinary course. It seemed to have resulted from some external toxic influence; I surmised a connection with the substance I had been working with at the time, lysergic acid diethylamide tartrate. But this led to another question: how had I managed to absorb this material? Because of the known toxicity of ergot substances, I always maintained meticulously neat work habits. Possibly a bit of the LSD solution had contacted my fingertips during crystallization, and a trace of the substance was absorbed through the skin. If LSD-25 had indeed been the cause of this bizarre experience, then it must be a substance of extraordinary potency. There seemed to be only one way of getting to the bottom of this. I decided on a self-experiment.

      Exercising extreme caution, I began the planned series of experiments with the smallest quantity that could be expected to produce some effect, considering the activity of the ergot alkaloids known at the time: namely, 0.25 mg (mg = milligram = one thousandth of a gram) of lysergic acid diethylamide tartrate.

      From LSD: My Problem Child by Albert Hofmann. I will leave it to others to explain all the ways in which this is absolutely hair-raising.

    I’ve gotten 2 skin burns from chemicals with a nitrile glove breakthrough time of <1 second

    underfunded undergrad lab classes without heavy duty gloves shouldn’t be allowed to use fuming nitric acid >:(

      I’m all fairness, nobody should be using fuming nitric acid unless absolutely necessary.

      At least you didn’t catch on fire. It likes to do that too.

    My uncle was a med lab tech in the hospital. They still had “no mouth pipetting” signs up in the late 90s.

    Do they still sell the Pipetting silly straws somewhere? I was in a Bio lab last week and they didn’t have any (but still told everyone to NOT pipette the E.Coli with their mouths) so I really want to try that now
