Are LSD and chest pain related?

Hey Doc, i have a question about some (presumably) LSD and chest pain i took:

So i got it from a reputable SR vendor  and tried out a single 100-125 ug tab. Only experience with drugs before this (except alcohol and tobacco) is weed a single time. I ate probably both too much and the wrong things (meat) before the trip, but i haven’t read that this could cause these pains.

In fact, the experience went pretty well. However, i had for some time this persistent ache in my leftmost chest. During the trip i took notes and described it as a warm feeling like my chest muscles/heart was slowly melting down across the chest. A week later i microdosed 25 ug and had that same feeling. It was a single, short stab of pain in that area as well. Not too extreme but strong enough to worry me.

It tasted only slightly metalic, not bitter as i’ve read NBOMES do, but mostly sort of sour, and the taste lingered slightly throughout the trip.

So, I hope it was just have been panic attacks (the first time was just fuck-all overwhelming, and i accidentally swallowed the microdose after some time and thought it wouldn’t work, so that trip wasn’t entirely expected either), but i’d like to hear a qualified view on it.

It is impossible to know what has happened without knowing the content of the substance.

Chest pain is a possible symptom of a panic attack after taking psychedelics, but it is usually accompanied by psychological symptoms (anxiety, fear, etc.). Chest pain of cardiac origin tipically is «tightness radiating to the left arm» and accompains with nausea and vomiting.

In fact, LSD does not produce noticeable cardiovascular effects. A few psychedelics currently available in the market (NBOMEs, bromodragonfly, DO-X) are  active in microgram doses. There substances are sometimes counterfeits of LSD. And all these substances have considerable organic toxicity, which is absent in LSD.

LSD blotters or drops fluoresce if placed under a black light (the type of light used in some nightclubs). The technique is a bit rudimentary but it allows at least to rule out certain counterfeits. So, a Drug Checking Service is the ideal option, if available.
