Final answer:
The penalties for underage use of alcohol, drugs, and firearms range from fines to incarceration, depending on the substance and state laws. Alcohol consumption under 21 is federally regulated, drug use penalties vary but could lead to criminal charges, and firearms are subject to serious penalties for unauthorized carrying, especially in public spaces.
Step-by-step explanation:
The penalties for the use of alcohol, drugs, or firearms in the age group of 13 to 20 vary depending on the specific circumstances and the laws of the state in which the offense occurs. For instance, the National Minimum Drinking Age Act of 1984 mandates that states set the minimum legal drinking age to 21, with states risking a reduction in federal highway funds if they do not comply. Under this law, underage consumption of alcohol can result in penalties ranging from fines to mandatory education programs or community service.
Regarding drugs, the legality and penalties can differ widely, but for a controlled substance like marijuana, possession or use can lead to arrest, fines, and in some cases, incarceration. Ryan's case exemplifies this, where testing positive for marijuana resulted in both school suspension and prohibition from participating in school sports, although it does not specify criminal charges.
When it comes to firearms, many jurisdictions impose strict regulations. For example, state law may prescribe a maximum penalty of eleven (11) months and twenty-nine (29) days and a fine not to exceed two thousand five hundred dollars ($2500) for carrying weapons on or in public recreational property. These laws are in place to ensure public safety, particularly in sensitive areas like schools.
