QFT. Stoney, you ever see that discovery 'how's it made' on flash frozen foods? They say that it sustains 98% of the nutrients. Wonder if that'd work for thc?
I don't know what QFT means. Too many abbreviations these days for me!
Here's and excerpt from a study on something close to what you've asked. The results show that it is possible to put thc into an inhaler, but it doesn't discuss the life span of the contents.

Abstract
The purpose of this study is to investigate whether spray freeze drying produces an
inhalable solid dispersion powder in which Δ9-tetrahydrocannabinol (THC) is
stabilised. Solutions of THC and inulin in a mixture of tertiary butanol (TBA) and
water were spray freeze dried. Drug loads varied from 4 to 30 wt-%. Various
powder characteristics of the materials were determined. Stability of THC was
determined and compared with freeze dried material. The powders, dispersed with
an inhaler based on air classifier technology, were subjected to laser diffraction
analysis and cascade impactor analysis. Highly porous particles having large
specific surface areas (about 90 m2/g) were produced. At high drug loads, THC was
more effectively stabilised by spray freeze drying than by freeze drying. Higher
cooling rates during spray freeze drying result in improved incorporation. Fine
particle fractions of up to 50% were generated indicating suitability for inhalation.
It was concluded that spray freeze drying from a water-TBA mixture is a suitable
process to include lipophilic drugs (THC) in inulin glass matrices. High cooling
rates during the freezing process result in effective stabilization of THC. The
powders can be dispersed into aerosols with a particle size appropriate for
inhalation.
