My friend was prescribed 8mg/2mg Suboxone last week and just injured her neck 2 days ago. She hasn't taken any Subs yet because she's nervous about how it'll affect her. Now that she's in pain she want to take one now. What can she expect? Will she get a buzz/high? Will it provide pain relief? Is the any chance of overdosing? She has a medium opiate tolerance as well btw. Thanks in advance!
