Is my dog going to die?

twenty minutes ago, i garnished a turkey sandwich with 25 mg of 2c-i and left it on the table when i went to get some soda. i came back only to see willis, my 100 lb golden retriever, eating my psychedellic sandwich. i put him in his kennel in case he gets violent, but i am very concerned for his life. what should i do? is he in pain? will he die?
