Hello, Cannot say in your particular case, but generally, changes in behavior such as being quite unpleasant to people, the use of inappropriate language, and starting a conversation with someone you want answers from are signs of mental changes associated with addiction. Generally stimulants or alcohol, not so common with opiates. Medication-assisted treatment basically works on this. Getting naloxone rescue medication might be even more important. Hope I have answered your query. Let me know if I can assist you further. Take care Regards, Dr Matt Wachsman, Addiction Medicine Specialist
