Thousands of people around the world struggle with HPPD every day; it may affect as many as 1 in 25 lifetime psychedelic users. Yet we know little about its risk factors and causes, lack optimal treatments, and the majority of clinicians are unaware that HPPD even exists. When interest in psychedelics is rising rapidly, it’s clear we need more research and better treatments for HPPD now. https://images.squarespace-cdn.com/content/v1/5fcb462d71eb421670f811cc/8c2da58d-0443-4acc-b3f9-a13fc3107517/lake.jpg https://images.squarespace-cdn.com/content/v1/5fcb462d71eb421670f811cc/1633227915600-6GTIPNLHXHTDAFRCXRJB/Logo_Static%2Band%2BEcho%2B-%2B02-16-2021-01.png HPPD Nonprofit - The Perception Restoration Foundation - Make it stand out Whatever it is, the way you tell your story online can make all the difference. https://images.squarespace-cdn.com/content/v1/5fcb462d71eb421670f811cc/ebc13c15-bdf3-4bd6-94e2-081c76005ddd/Logo_Static%2Band%2BEcho%2B-%2B02-16-2021-01+%281%29.jpg HPPD Nonprofit - The Perception Restoration Foundation https://images.squarespace-cdn.com/content/v1/5fcb462d71eb421670f811cc/4de9d8f7-6234-44e8-b2f4-0e87614784f9/unsplash-image-Z0vdRzr_iZM-min.jpg HPPD Nonprofit - The Perception Restoration Foundation https://images.squarespace-cdn.com/content/v1/5fcb462d71eb421670f811cc/9ba56fa5-7cf9-443b-9706-77f764612464/Untitled%2Bdrawing%2B%282%29-min.png HPPD Nonprofit - The Perception Restoration Foundation https://images.squarespace-cdn.com/content/v1/5fcb462d71eb421670f811cc/e827d897-4043-40a7-9fa0-6d81105db343/unnamed-min.jpg HPPD Nonprofit - The Perception Restoration Foundation https://images.squarespace-cdn.com/content/v1/5fcb462d71eb421670f811cc/e4c667ea-a3db-44cd-a78c-3e2297630dc1/vice-og-min.jpg HPPD Nonprofit - The Perception Restoration Foundation Graffiti-style white text on black background that reads 'VICE'. https://images.squarespace-cdn.com/content/v1/5fcb462d71eb421670f811cc/1aa2cd95-6fda-4c8b-ae78-c1368bcf1522/PsychedelicsToday_logo_horizontal_color_LightBackground.png HPPD Nonprofit - The Perception Restoration Foundation A colorful, stylized eye with rainbow hues and radiating lines next to the text 'OpenAI'. https://images.squarespace-cdn.com/content/v1/5fcb462d71eb421670f811cc/b7dca78c-d45a-48d5-a77a-f33eeef088a8/MIAThumbnail_0.png HPPD Nonprofit - The Perception Restoration Foundation A diagram of a human head with labeled brain regions and a title that reads 'Mad in America'.
