Did I come up with a fullproof plan to buy weed and not get caught?

So I recently started smoking weed and I enjoy it very much.I am however extremely scared of getting caught by the police. I thought long and hard about this plan and I need you guys to identify all possible Flaws. So hear goes, I live in the suburbs and so does my dealer, so I walked to his house and bought my weed. Before leaving I tied my weed to the thinnest fishing gut available. It's extremely strong practically invisible. The piece of fishing gut I used was extremely long. Close to 30 meters. So I tied my weed up with one end, and I had the other end in my hand. So basically I walked back home holding a piece of invisible gut with my weed trailing 20 meters behind me. If I see the police or anything suspicious for that matter, I simply let go of the invisible gut and continue walking. The police can stop and search me and they will find absolutely nothing. Please identify any flaws in my plan.
