This way of getting high could predate LSD craze (10)
I believe the answer is:
stepladder
'this way of getting high' is the definition.
'stepladder' can be an answer for 'way' (stepladder is a kind of way). I'm unsure of the rest of the definition.
'predate lsd craze' is the wordplay.
'craze' indicates an anagram.
'predate'+'lsd'='predatelsd'
'predatelsd' anagrammed gives 'STEPLADDER'.
'could' is the link.
Can you help me to learn more?
(Other definitions for stepladder that I've seen before include "piece of equipment" , "Help for climber" , "Portable means of ascent" , "Painter's mate" , "Portable climbing aid" .)
