LAST EDITED ON 03-04-10 AT 05:13 PM (EST)I think it depends on where the conservative parents thing edited in.
I did drugs as a teenager
I didn't do enough to ruin my life or anything
A lot of drugs are fun and recreational
Parents are too conservative
I hung out with hippies at 26
But hey whatever adults want to and drugs are all rock and roll
If the progression was like that then it implies parents really should just let their kids have fun with drugs.
Now a lot of interviews do take things out of order, so he may have made a comment about parents somewhere else in reference to something else.
It is hard to know, but they could have put that line anywhere else but put it in a place to make it sound like it was in reference to his recreational drug use not at 26 only after the hippies but also as a teen.
ETC: one somewhere to a something.
