If you get caught with drugs,especially selling,the cops are gonna press you to sell out someone highier up the latter.There not gonna use nice tatics,they can lie,etc but it's legal.Your friends should just keep quiet and get a lawyer. Since it's a small amout your friend should just get probation,they should ask about an acd.Maybe a lawyer can lower the charge or get it dimissed somehow. Your friends should be more concern how a conviction for selling drugs is gonna effect them in the future,finding a job,etc.A little proabtion a fine,whatever,then 5 years from now it will bite them in the ass.
This why it's a bad idea to be w. a lot ppl when there various drugs around,it just creates so much hassle.
