I read about your qualms concerning your grandchild going to school in Colorado. Honestly, I think the idea of legalizing marijuana is a definite trend being discussed/examined/argued in most states.
While I can understand your concern, if the institution offers what the student wants, and he or she understands the responsibility of NOT letting marijuana become that much of an attraction, then I believe going to school in this beautiful state would be a good experience.

Not to worry ….if the beautiful State of Colorado tolerates the sale of liquor, we’re ok with marijuana. People just have to use their heads!
Thanks, Ellie. BTW I know another wonderful Ellie Cunningham here in Philadelphia!
Is marijuana use any different from alcohol use or tobacco consumption?
All can be used “sensibly” or can become addictive. Even prescription
drugs can become addictive. So, in my view, it’s not the product so much
as the values of each individual as to how these products are used.
