As an 18 year old guy, my girlfriend and I sat and watched and all in all, part one came across as a message to young people that while drug addiction is one hell of a ride, you'll come out the other side and the ups will be nothing short of amazing.
Cousins is far from in the clear from the drug abuse, didnt you watch the part involving Mainwairing collapsing to his death?
what if Cousins is to collapse and die befoe his 40 due to drug abuse? hardly coming out the other side i would think....
