There's way too many negative effects for me to want to try it. Even on the website yuki recommended himself it says so.
I don't want to have the munchies.
I don't want to hallucinate.
I don't want to have trouble sleeping.
I don't want unusual tension.
I don't want nausea.
I don't want headaches, blood-shot eyes, altered vision, coughing, lightheadedness, dizziness, confusion, drymouth, loss of coordination, poor time sense,
...and I don't want to be addicted to marijuana.
It may not be considered a drug, but it's still bad. Plus the fact that it costs money and might be getting more expensive due to the fact that it's illegal, which also means I probably have to hang around the druggies behind the school waiting for a dealer to come. Correct me if I'm wrong about means of acquirement.
