I’m not an audiologist but I go to a lot of shows and bars and I care about my hearing. I swear by Flare Earshades and I recommend them all the time.
I’ve tried Etymotics, Loops, Vibes, Earasers, and a couple other brands, and none of them have the clarity and quality of the Flares. I’ve worn them comfortably for 8 hours, and music sounds so good I forget I’m wearing them.
This is just my experience, and you’ll find lots of positive reviews for other brands, but I wanted to share mine.
I’m not a medical researcher, but I can tell you that the random LSD flashback, as you’re describing, is not evidence-based. As with many drugs, LSD releases glutamate and can trigger psychosis in people predisposed to psychosis. This can lead people to believe that LSD is somehow being stored in their body and activated later on. Something similar may be happening when people have a bad experience smoking weed and insist it was “laced” with another drug. LSD is processed by the liver and isn’t “stored” anywhere, unless you count blood during the several hours before it’s fully metabolized. Also, we already prohibit LSD-driving. Driving recklessly while under the influence of a substance can get you arrested and get your license revoked.
Please be careful about spreading misinformation.
