beachguy in thongs Reviewed by beachguy in thongs on . Can smoking MJ in excess..be harmful?? Everyone know's Marijuana is harmless but when used in excess does it have the potential of having a negative effect on one's daily life? Or does it really matter on the person? Seeing that some function better on the long-term drug use than others. Rating: 5
