trip out

I'm a little stuck... Click here to teach me more about this clue!

'get stoned' is the definition.
(synonyms)

'journey from home' is the wordplay.
'journey' becomes 'trip' (trip is a kind of journey).
'from' says to put letters next to each other.
'home' becomes 'out' (I can't explain this - if you can you should give a lot more credence to this answer).
'trip'+'out'='TRIP OUT'

'to' acts as a link.

Can you help me to learn more?

(Another definition for trip out that I've seen is " Stop working, currently".)

I've seen this clue in The Independent.
