CASE STUDY: THE EFFECTS OF MARIJUANA
A 57-year-old physician had abused marijuana for 30 years. We performed this SPECT series because he had been unable to stop using without feeling very angry, irritable, agitated and anxious.
The study was performed after he came to the clinic intoxicated from 3 straight days of heavy usage. The scan shows marked overall decreased activity, especially in the prefrontal cortex (PFC) and temporal lobes – areas associated with attention, memory and motivational problems.
