Meaning of "Know the local drug scene for yourself" in “What Every Kid Should Be Able to Do by Age Sixteen”

From “What Every Kid Should Be Able to Do by Age Sixteen” by Audrey Sutherland:

• Read a topographic map and a chart
• Know the local drug scene for yourself
• Handle a boat safely and competently (canoe, kayak, skiff, sailboat)

The bolded phrase seems out of sorts with the rest of the list. Does it mean "a kid ot 16 should know where to get illegal drugs"? It puzzled me. I’m not a native speaker, maybe I’m missing something.

What is the true meaning of this?
