Perform a follow-up scan. Go back to the same area where you completed an initial cigarette litter scan and scan again to confirm the program is making a dent in reducing cigarette litter. This will provide concrete results. Re-scan any time between five weeks and three months after the start of a Cigarette Litter Prevention Program.

Gauge public awareness. Check in with how well the program is making local residents aware of the issue—and the city’s program.  Track media coverage.  Consider a small resident survey to measure public awareness.
