Murder Or Suicide Puzzle

I think it is a murder and not suicide. Reason:
1. Since the gun is on the right-hand side and the blood is splattered on the right-hand side of the wall which indicates it is not a suicide.
2. Also, if it is suicide, the victim must have waited for the cigrate to end.

Note: There is no definite answer for this question and it can be suicide or murder based on user perspective.
