ive been smoking for 2+ years and ive got caught 3 times

1st: Smelled like weed, searched me, found my weed and took it.
2nd: Went swimming, mom searched the pants i was wearing, found my day old pipe. looked at it, looked at me, and put it back.
3rd: Left the same pipe laying around, mom took it. (but i took it back, dunno if she knows yet )

All within a months timespan. When you finnaly get caught that first time, you'll get caught a fuckload after that.
