Krystle Weber probably should have skipped this lesson: letting friends teach her 2-year-old son how to smoke pot.
A cell phone video caught Weber sitting in a room as her friends showed the boy how to smoke a joint.
"I swear to God, I better not get in trouble for all this," Weber, of Wisconsin, said in the video.
The video captured the incident 7 months ago, and Weber and two of her friends have since pleaded guilty in the case.
A test after the incident did not find marijuana in the boy's system.
Weber's also taking parenting classes -- has her son back.
