My roommate ingested about 1.5 grams of black tar over the period of 4 hours. It has been 2 hours since he ingested anything- and he wants to just sleep now.? He took 5 mg ambien about 1.5 hours ago as well as H doesn't out him to sleep. He usually smokes .7-1.5 g when he does so nothing out if typical dose range. I spoke with poison control and they said it sounds like everything is going in the right direction. Should I let him go to sleep or no?
