You're legal to use your friend sonlong as ge meets the remainder of the requirements set forth in 14 CFR 61.55. This includes, among other things, an instrument rating, aircraft familiarity, and three takeoffs and landings as sole manipulator of the controls, crew resource training, inflight maneuvering with an engine out whole performing PIC duties, etc, with ine previous 12 months. Then you can "dump" your friend in the right seat for a trip.
