Trippy really depends on your surrondings and your frame of mind...

if your 15 yrs old in your bedroom about to drop a hit of acid u might want to rethink. Most likely you'd take it... start tripping balls.. do something to wake up your parents, and end up in the psyc ward becuase u think your a gorilla

if your 15 yrs old and in the right place... I think a younger kid could handle a trip as long as hes happy before the trip. If your a depressed kid or have lots of problems in your life and are unhappy u never want to trip!!! If your happy you'll trip happy
