White Smoke Blowing Out of Air Vents

I have a 2002 Civic EX and I was driving on the highway, when I noticed this white smoke blowing out of the air vents. The smoke did have a smell to it almost like freshly cut grass. Now I did just recently recharge the freon last week because my A/C was blowing warm air. After I noticed this smell I turned the A/C off immediately and turned it on 20 minutes later and there was no smoke. Could this be a freon leak in the air conditioning system or could it be condensation due to the humidity and rain that I was driving through? If someone could let me know what this problem is and how to fix it that would be great. Thanks.

AC is still nice and cold? If it is, then you didn't lose any freon.

You had it set on fresh air on a rather humid day. You witnessed a cloud, literally, of water vapor. It's a natural phenomenon under a certain set of conditions.

Use recirculated air instead of fresh air.

Overheating or loss of coolant, heater blowing cold
