Aircraft
As we were climbing though FL250; we had a Pack 1 Overload message appear on the EICAS. We ran the Pack 1 overload QRH and the reset was unsuccessful. Therefore the QRH instructed us to leave the number 1 pack off and descend back to FL250. We determined that we had enough fuel to continue the flight at FL250 and then flew approximately another 20 minutes. We then smelled smoke in the cockpit and visually saw smoke coming from the FO's (First Officer) vent below the side or DV (Direct Vision) window. We completed the memory items for the cabin smoke and ran the cabin smoke checklist. I [advised ATC] and stated that we needed an immediate descent to 10;000 ft. A couple of seconds later; the FA (Flight Attendant) called the cockpit on the interphone and told us about the smoke in the cabin. At this point we began an emergency descent to 10;000 ft. The smoke continued to thicken until we reached 10;000 ft and the FO turned off the number two pack. The smoke dissipated with both packs off and the recirculation fan off. At this point we were only 15 minutes away from ZZZ. After a quick follow up with the FA she confirmed that everybody was ok and that the smoke had dissipated. We chose to continue on to ZZZ where emergency vehicles could assess our situation before pulling into a gate. I made a PA to the passengers stating that we believed that the smoke was under control and that we had no indication of further problems. I told them our location and that we had chosen to continue on to ZZZ. The FO did a great job flying the plane under pressure and the FA maintained her composure while assisting and briefing passengers. A safe landing was made.The aircraft was visually inspected by the fire department and no abnormalities were found. I then made a PA to passengers about our intentions to return to the gate and that the fire department had given us the green light. Before taxiing to the gate; I called the FA on the interphone and asked if she was ok. She confirmed that she was fine and the passengers were fine and on their seats. We then taxied to the gate where the fire department did their follow up paperwork.
