Narrative:

Both [C flight attendant] and I smelled a strong smell of marijuana when passenger exited aft lavatory. Shortly after; we both felt our throats burning. C flight attendant said she also saw smoke inside the lavatory. Passenger also seemed paranoid. We called the captain and notified him of the events.police met the aircraft and questioned the passenger. Initially passenger lied to the police saying he didn't do anything. Police officers and tsa came onto the plane looking for evidence and could not find anything. When we deplaned the aircraft we stayed in the gate area while on the phone with operations. In the gate area; we noticed the passenger shaking the police officers hand and walking away. As he was walking away; he dropped the vape pen on the ground and picked it up. We notified the police and they detained him. The police tested the vape pen and it tested positive for thc (marijuana). The passenger then confessed to smoking in the back lavatory and in the cabin among other passenger. At the time of writing this; my throat is still burning and I have a headache. I do feel a little off and not sure if it is the stress of the event or effects of the thc.
