Summary
THJ-018 (1-naphthalenyl(1-pentyl-1H-indazol-3-yl)-methanone) is a synthetic cannabinoid and analog of JWH-018. It has been marketed by many research chemical vendors as a legal alternative to the popular JWH-018, which had been banned in 2009. Its appearance is a brown, sticky and chunky powder. It smells very similarly to naphthalene. Cannabinoids are commonly smoked or vaporized to achieve a quick onset of effects and rapid offset. THJ-018 is orally active when dissolved in a lipid, which can increase the duration significantly. Like other cannabinoids, it is insoluble in water but dissolves in ethanol and lipids.
