hey,i have a volcano vaporizer and i call the used pot' vapor dung'.anyhow my 'dung' is always really light brown.since a vaporizer turns the smoke into vapor i believe it would take longer to expell it all from one's lungs,or i would think so anyhow.therefore you would think that you are breathing out vapour smoke.anyhow have a grand time with your new toy,farmgirl
