Conversion of CBD to THC with citric acid and water-based extraction

Yellow-warning-sign1.svg

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.
