You and your "Homie" planning on hanging out and smoking in front of the cop shop?Yeah leave it in the hands of the Judge to decide my fate on how much jail time i will do for smoking a joint with my 20 year old homie!. No thanks!
Use a little common sense and you will never have any LEO run ins.
If your homie is 20 now, then by the time this passes he will 21 or close to turning anyway.
