was given some opium and a pipe by a friend, I have like 80 wound points from various wounds that it's supposed to heal up. However nothing is happening. The effects kick in and I get the "chasing the dragon" buff, but it's not absorbing the damage. Apparently under the buff info it's supposed to list how many wound points it's healed but it says nothing.

This has happened before but it hadn't occured to me until now. It's just not doing anything. Do I need to do something other than just light it up?
Thanks
