It was several hours after taking a large dose of the psychedelic drug LSD that things took a turn for the worse for Nadia. She and her friends were lost in a park and had to ask for directions to get back to the main road. The only people there to ask were police officers, and she suddenly became hyper-aware that she had taken an illegal substance. Nadia started feeling anxious that she would get in trouble and got paranoid — worrying, for example, that somehow her cats got into the LSD and would be poisoned.
She wanted the trip to end, so she turned to her antipsychotic prescription, which she takes daily. She had read online that it could reverse the effects of a so-called “bad trip” and had some on hand prepared for this very reason.
