Substance Abuser Needs Help

I have recently read articles on the subjest of psychodellics (sorry
for my spelling) being beneficial to substance abusers who are trying
to quit, and need a lift/change-of-pace in order to have the spiritual
experience to escape the trap they are in.

I hate my coke addiction.  I am a 12 step relapser.  I need to expand
my thinking like I did once or twice when in my teens.

Of course this is all hypothetical!  But for ficticious fun, where can
a person go to find / procure Lucy in the Sky with Daimonds?

I live in Orange County California, and am looking for an area,
coroner, park, cross streets from Frisco to Los Angeles?

Any insights (again, just for ficticious fun) would be extremely
helpful!

Thanks!

Dave
