7th Heaven S03E08 - No Sex, Some Drugs and a Little Rock 'n' Roll

After drinking Matt's coffee once, Simon fears to be addicted and acts accordingly. A natural, legal 'supplement' is offered to study-exhausted Matt by buddy Scott, whose pa got it in a health store, and to Mary by over-competitive teammate Diane Butler, whose father uses it himself. Eric realizes it contains dangerous epefrine. Eric's former rock band mates visit Glenoak. Matt sets something right. The Butlers are in for a shock.
