My (ex) boyfriend admitted he spiked my food/drinks and raped me more than once while I was asleep. ?

Throwaway account for obvious reasons.<br><br>My boyfriend admitted he spiked my food and drinks with marijuana and xanax, and then had sex with me while I was asleep. I confronted him about why I wake up so often in the middle of the night, and whether or not he was sexually assaulting me at night. He admitted that he had sex with me while I was asleep on multiple occasions, and that he also did it to his last girlfriend. He also admitted to giving me drugs and alcohol in my food and drinks that I specifically told him I did not want. When I confronted him about it, he said he thought I was joking about being scared of being drugged and sexually assaulted. I am no longer in a relationship with him.<br><br><br>My question is whether or not xanax and marijuana could make a person so drowsy they wouldn't even wake up during intercourse? He admitted that he did this multiple times, including on nights when we didn't even have sex before going to sleep. I don't know if I just very easily forget because of the drugs, or if he was lying about the extent to which he was doing this.
