Anthony, Criterion H does not necessary negate the possibility of PTSD. Consider these two hypothetical situations:
1. A person presents with symptoms of PTSD, but has substances in the body or recently used substances. PTSD would not be diagnosed.
2. A person presents with symptoms of PTSD and substances have not been in the body for several years. The diagnosis of PTSD is a possibility because the disturbance is not due to substance use at that point; it is due to a traumatic event that just happened to involve a narcotic.
It doesn’t make sense to say a current disturbance is due to substance use when a person hasn’t used a substance for several years. I understand that an LSD trip is quite different from a real experience, but it really isn’t very different for the person who has a bad LSD trip. It is very real and very traumatic for that person and it can affect the brain in the same way.
