HPPD & Marijuana

[420marijuana420]

Can HPPD be caused by marijuana? I read a thread a while back that briefly touched on it but it wasn't really that informative. After I read the thread I notice kind of static vision but I think it was because I noticed it after that thread.
Can anyone shed light on this for me?

Not sure if you checked there already, but Erowid has a great vault all about HPPD.

4. What causes HPPD?
HPPD is defined to be caused by taking 'hallucinogenic' drugs, but its root cause is poorly understood. Dr. Henry Abraham ( a leading researcher in this area) believes that HPPD may be partially genetic though he says that he knows of no published evidence [personal communication - tacovan]. It seems to be most commonly related to LSD use, perhaps because LSD is the most common hallucinogen, but there are also reports of HPPD being caused by other psychedelics such as mushrooms, MDMA, MDA, 2CT7, 5-MEO-DiPT, etc. There are a few people who have HPPD-like symptoms who have never taken any drugs, but the definition of Hallucinogen Persisting Perceptual Disorder does not include these individuals.

Based on anecdotal evidence HPPD subjects fall into two broad categories. A large percentage (probably the majority) got HPPD fairly early in their experimentation with hallucinogens. They also seem to get fairly severe cases of it. Dr. Abraham also confirms that this appears to be the case and says this is one of the reasons he believes HPPD to have genetic origins. For further information see (Abraham HD. Visual phenomenology of the LSD flashback. Arch Gen Psychiatry; 40: 884-889, 1983)

The second set of users are long-term drug users who got HPPD well into their experimentation with drugs. These people report that they get HPPD from a wide variety of drugs. Since most long-term users of multiple drugs also use LSD, it is hard to really distinguish what drugs are responsible for HPPD in these cases. However, there are a numerous reports of long-term drug users who had strong trips on non-LSD drugs which led immediately into HPPD symptoms.

Ok, after reading that then I don't think I even have it anymore because I thought I might have the static but the stuff I see isn't like tv static it's just kind oflike particles I see infront of me.
