I was going to type exactly what she did. Exactly. If he does have Aspergers (and he sure has all the signs) he is different and struggles more than most people to understand people and to fit in. Therefore, he is attracted to misfits who he feels at home with and is susceptible to doing what they do.
My daughter was extremely shy and we had just moved so s he was new in seventh grade and nobody paid any attention to her. She sat alone at lunch and felt bad. Finally the "bad" kids came up to her and included her and she joined them gladly because nobody else would have anything to do with the new girl. She told me the same story I keep hearing here: "They were the only ones who included me." She was twelve years old and that was when she smoked her first joint. by the way, in our family nobody smokes cigarettes or even drinks a beer and she still did all that stuff. Thankfully, she even quit the cigarettes!!!
Your son is young. Hopefully he will quit too.
