Since I am the GM, if it is by the RAW, yes.
The RAW states "The character must spend time in daily meditation, trying
to consciously bring the physical, mental, and astral aspects of
her being into perfect balance. To achieve this, the character
must succeed in two Extended Tests"
It seems clear to me that if your character is deliberately throwing those aspects OUT of balance, though the use of either drugs or sustained spells, then he will no more succeed than if you try to rebalance your car tires by adding weights to the sidewalls. You may succeed at your tests, but you will fail at your intended purpose.
In short: Drugs & Magic let you successfully meditate, but do not bring your aspects into balance. No discount for you.
Alternately, let it succeed but slap the new Initiate with a Severe Addiction to the spell or drug, and have him unable to gain the benefits of initiation while he is not under the influence. ...yeah, I like that more, I think, it makes a lot of metaphysical sense.
