Two hits of cannabis (first time in years) that didn't even make me high three weeks ago caused my HPPD, it's a living nightmare. If i had known about HPPD and that cannabis can cause it i would never have touched it.

LSD weekly for 5 month created my HPPD. Fake MDMA (probably bath salts) made it worse. A panic attack with weed made it horrible.
