Great high THC oil is sourced from clean, well-grown cannabis that is rich in cannabinoids and terpenes. Some things to consider when evaluated the source material include:
The quality of strain genetics
Freshness of the starting material
What part of the plant was extracted
How carefully the cannabis was handled after harvest
Not only will extracts consolidate the desirable qualities of the strain, but they’ll also concentrate any negative attributes or contaminants found on the plant; that means any defects will be amplified in the high THC oil. That’s why the best cannabis oil comes from clean, high-quality cannabis flower.
