Jerry stressed that he didn't know if this is what happen in Hoffman's case, but that it was common for addicts coming out of a relapse to overdose in this way.
Details surrounding Hoffman's death are still emerging. By his own admission, the actor struggled with drug problems for years, beginning in his twenties.
Hoffman said he had kicked the habit for 23 years and had remained drug free until May 2013, when he briefly relapsed. He admitted to snorting heroin and checked himself into rehab.
Shrand said that no one should think of an addiction like Hoffman's as a moral issue.
"This didn't happen because he was weak," Shrand said. "This was an actual physical thing driven by the brain and his addiction didn't go away just because he didn't use for such a long time."
