Here are some of the more popular slogans against drugs, but the way to combat drugs is with honesty, no slogans or propaganda or Reefer Madness type lies in films

Just say no
I'm too good for drugs
Drug free is the way to be
Don't choose the booze
If you choose the booze, you lose
What's your anti-drug?
Stay alive. Don't drink and drive
Shoot for the stars not your arms
Smoking the dope won't help you cope
Up with hope, down with dope
If you know Jack, you won't smoke Crack
This is your brain. This is your brain on drugs. Any questions?
Drugs are retarded, so don't get started
Say Not to Pot
PCP bad for me
Kiss meth mouth goodbye
Hugs not drugs
I'm above the influence
Pot makes your brain rot, so lets not
Get High on Life, not on Drugs
You don't need Heroin to be a hero
Be aware, don't share
