Well, it's been about eight months now since my bad trip and I still cannot smoke weed without freaking out. I've tried several times, but even just one hit of schwag makes me very uncomfortable. A couple weeks ago I had two medium hits from a bong and had to lie down for a few hours until things became less intense.

I've done some research and believe I have Hallucinogen Persisting Perception Disorder. My doctor diagnosed me with Panic Disorder, which is common for people with HPPD. The effects of the HPPD faded after a few months, but use of weed or opiates tends to revive them.

I find this knowledge very depressing, as it seems it's common for weed to do this to people with HPPD. Sometimes they can smoke again after some period of time, but sometimes it takes many years. Weed was my one great love. I just wish I could blaze again like in the good old days.
