THCJD provides a long-lasting high that lasts from 1-4 hours, depending on the amount you use and your tolerance. Regardless, THCJD is a treat for experienced consumers who need something stronger. THCJD is stronger than Delta-9 THC, it is also a great choice for people struggling with mental illnesses such as depression, PTSD, and other mood disorders. THCJD can dramatically calm the mind, but if taken in high doses, it can cause some anxiety and paranoia in people with lower tolerances.
