Actually, flashbacks do occur but its usually not too long after the experience. Those who claimed it was even stronger and lasted for years probably have another problem very different. Normally its much much milder but you get into the experience with something going on and are able to hallucinate. Which we all do every night.
Other lies we were told was that someone looked into the sun for a long time and was blinded. Not true. Then they said it caused dna damage, also not true.
About pot they said you became addicted and violent. More likely to become a lazy slacker I'd say, ha.
Not sure where you get your information, but both of your ‘not true’ statements are
not true. UV light from the sun can and will burn the retina if you look too long, which
can cause blind spots and/or blindness. If you’ve ever heard of skin cancer from too
much sun exposure, then you know exposure can alter DNA.
OT: I’ve experience state of mind changes through yoga and meditation, just incredible
experiences for me. I think in many ways music alters my mind as well.
