Drinking age debate questions

Pro:
At age 18, we can not only choose who represents and leads our country, but we can also go and die for our country, whether forced or by choice. We can also expose ourselves to addictive substances that are found in cigarettes and tobacco. Why then can't we choose something as simple as what we drink?

con:
If you lower the drinking age to 18, what would prevent high schoolers from easily accessing alcohol from their older friends.
