Conversion of CBD to THC with zeolite

From PsychonautWiki Archive
Jump to navigation Jump to search

THC produced from converted CBD is very potent

It is nearly impossible to guesstimate the potency from home-made extraction, but even low potent extract significantly increases the risk of a psychosis compared to consumption of potent cannabis buds. However, synthetic cannabinoids, unlike natural psychoactive ones like THC, have been attributed to significantly more deaths, with cases like MDMB-FUBINACA exceeding 1,000 hospitalizations and 40 deaths.

Zeolite is a type of microporous aluminum silicon that contains negatively charged anions. When CBD is heated to around 100°C, these anions attract the CBD molecules and cause them to rotate, similar to the effect of acids.

Expect the CBD to isomerize to maximum 10% THC with this tek.

Materials

  • 1 g CBD
  • 500 mg zeolite in the form of analcime, chabazite, clinoptilolite, erionite, mordenite, phillipsite, or ferrierite.
  • 13 mm diameter non-sterile syringe filter with a 0.22 µm pore size hydrophilic PVDF membrane.
  • 13 mm diameter non-sterile syringe filter with a 0.45 µm pore size hydrophilic PVDF membrane.
  • 13 mm diameter non-sterile syringe filter with a 0.02 µm pore size hydrophilic PVDF membrane.

Procedures

  • Mix the zeolite powder
  • Heat it at 130 Celsius for 10 minutes. A simple glass beaker on a typical hob plate has been used (see this video, however, ideally a temperature regulated magnet stirrer is used.
  • Let the solution cool.
  • Dissolve it with 10 grams isopropyl alcohol (IPA), to make a liquid solution.
  • Aluminum compounds should not be smoked nor ingested. Let the zeolite sediment. If you are eager, filter the zeolite.
    • Pre-filter: 13 mm diameter non-sterile syringe filter with a 0.45 µm pore size hydrophilic PVDF membrane
    • Filter: 13 mm diameter non-sterile syringe filter with a 0.22 µm pore size hydrophilic PVDF membrane
    • Filter: 13 mm diameter non-sterile syringe filter with a 0.02 µm pore size hydrophilic PVDF membrane
  • Add 20 grams seed oil (for example sunflower oil) if you are going to ingest it.
  • Evaporate the IPA.
