Anti-Drug Campaign

Continuing on with research today to help blossom my design ideas for my poster, I have come across some interesting posters online in relation to Anti-Drug Campaigns.  As you can see, the posters are only reminders...where are the dangers or actions to help those in difficulty.  I am thinking my poster with action guidance will be very unique as I cant seem to come across any!

What next? What information will be involved on my poster and little drink coasters
