Though it may seem fun to try with your friends, smoking weed could hurt your lungs and cause breathing problems that impair athletic skill. The temporary high also causes trouble thinking and concentrating which would leave you unable to focus when doing a test. Not to mention that it is illegal for minors. Getting caught would result in criminal penalties.
Will it jeopardize your friendship?
If you decide to refuse and walk away or try to prevent your friends from smoking...
What if something happened to your friends after you left?
Will they think your lame and boring?
With refusing to smoke, you will avoid potential health consequences as well as avoid the risk of getting caught. But refusing to smoke may make you look lame and cause your friendship to weaken. There's also the possibility that some kind of accident could happen to your intoxicated friends after you left. Then there will be no one there to help them.
You and your friends make it to the park.
You guys ready!?
I'm not going to smoke, and I don't think you guys should either.
I don't want to get caught, nor do I want memory and mental health problems which are the long-term effects of THC found in Marijuana.
