You could be right, and I also have ADD - but I've read that people with autism spectrum disorders usually have abnormal neurotransmitter activity. In particular dopamine, serotonin and GABA. They say that serotonin is the "pleasure" transmitter and dopamine is the "excitement" transmitter. Often autistic people are less receptive to activity in either. As a result of being less receptive to the activity of neurotransmitters, I think it could be argued that addiction is less likely since addiction is caused by increased neurotransmitter activity? Feel free to correct me if you know more on the topic.
