You are growing Anaheim peppers when you have your best friend over to look at your garden. Your friend really likes peppers and you allow him to pick some after he puts out his cigarette. You also allow his little sister to pick some and she sneezes on the pepper plant. Several weeks later you notice some of your plants' leaves look like brown blobs with a white circle in the middle while others have yellow spots. You have less than a normal harvest, and the plants are small. What's the disease?
