What Causes Heart Palpitations, Sleeplessness And Lack Of Cognition After Smoking Hashish?

Hi, My boyfriend and I just smoked dabs (hash oil) with a friend yesterday evening. We each took one hit and I was fine soon after, as was anyone else in the room who smoked it. My boyfriend, however, who was not under the influence of any other substances, has had racing thoughts and delusions, cannot sleep, and his cognition seems off. He has gotten much better than immediately following, but has not returned back to normal. I feel that he needs to get some sleep to reset, but he insists that he is unable to sleep. He doesn t remember taking anything else prior or since (and hasn t as far as I know), insists he hasn t, and that he didn t fall and hit his head or anything like that. It was a very small dose and I have since been monitoring him with a friend. Do you feel that this is an emergency situation, and should he be seen by a doctor?
