Narrative: During the takeoff phase (at around 600 AGL); the Captain asked if I smelled smoke. I wasn't smelling anything and stated that while switching to departure and dialing in the new heading Tower had assigned. Before I could make the call to departure; the Flight Attendant (FA) called to the front using the EMER button instead of a normal call. I immediately called ATC for a level off and delay vectors.I could see and smell smoke at this point. I told the Captain I was putting on my oxygen mask; we established communications; and I talked with ATC while the Captain gathered information and briefed the FA. The FA was calling to the front because he had seen dark smoke rising near zones E and F. We [notified ATC] and got vectors back around for an ILS approach. We landed without any other issues and stopped on the runway to have fire and rescue drive around the aircraft to inspect. They reported nothing out of the ordinary and after talking with the FA; we determined the smoke had dissipated and we could return to the gate to deplane.Cause: After talking with maintenance we speculate the cause of the smoke was deice fluid getting blown into the engine when we were deicing. Smoke seemed to be coming out of the packs when the event happened. We followed all checklists on the ground during the deice procedure and made sure to do the run-up on the ground. No smoke was noted during that process.


Second narrative: On takeoff; smoke started coming out of the vents in the cockpit and the cabin. The First Officer (FO) and I donned the O2 masks and at this time; the Flight Attendant called to report smoke in the aft of the aircraft. We leveled off at 4;000 and requested vectors for a return to field. By the time we were setup on approach; the smoke had dissipated significantly and the Flight Attendant reported the same for the cabin. After landing; we had the fire department inspect the outside of the aircraft for any signs of smoke or fire. Reporting none; we decided that we should taxi to the gate for a normal deplaning.Cause: We suspect anti-ice fluid got into the pack inlets due to high winds while deicing. 40 knot winds were coming directly at the tail of the aircraft.Suggestions: Pointing into the wind for deicing could help.


Synopsis: CRJ-200 flight crew reported they experienced smoke and fumes on takeoff; and cabin crew subsequently reported fumes in the cabin.
