No I'm sorry....that was way out of line. clearly i got more annoyed than I should have as well.

If you're still willing to entertain my thoughts: I'm not arguing anything but statistics. I'm sure HPPD is a real thing but how often does this manifest? What drug do you have to take? How much? How often?

It doesn't seem fair to list it as a legitimate concern for all psychedelics if it affects 0.001% of the population (for example) or only people with predispositions to such things.

And to be fair, you DID start by saying flashblacks not HPPD and then switch to HPPD. I would not have entered this debate if you had said HPPD from the beginning.

You didn't seem to like my analogies so how's this one: It would be the same as saying "I've never had a beer because I know alcohol causes alcohol poisoning" It's technically a real concern but lacks any kind of common sense or awareness of how alcohol poisoning occurs.
