i've been caught once, by my parents. after i had been smoking for about a year, my mom said that my behavior was "suspicious" and so one day we got in the car, and she didn't say anything for a few minutes. then she turned to me and said "have you ever smoked pot??" and i was completely shocked, not expecting that. unfortunately, the weekend before i was caught, i had smoked a ton since it was a friends birthday and we were all celebrating. so i knew that i was completely fucked no matter what. my parents grounded me, but luckily i was leaving to go off to school the next month. so i was only grounded for a month. now, 2 years later, my parents have no clue that i still smoke since i have my own apartment 5 hours away from them.
