Please DO NOT spray hydrogen peroxide on your buds. I don't care if it works or not.
How to degrade THC into CBN:
1) Apply low heat over time (throw it in the sun, covered, for a week)
2) Naturally over time (we're talking 3+ months in a glass jar, after curing)
3) Subject the buds to light (throw it in the sun, uncovered, for a week)
4) Volcano/etc: Set temp to boiling point of thc, run 1-2 bags worth to deplete thc. Raise temp to deplete remaining cbn + cbd, etc.
You can use any combination of these to lower the amount of thc in your smoke and convert it to CBN (which is similar in affect to CBD).
If anyone has corrections for this - please make them; as I'm writing this from my (awesome) memory. Happy toking.
