Summary
STS-135 (also called N-(adamantan-1-yl)-1-(5-fluoropentyl)-1H-indole-3-carboxamide or 5F-APICA) is a drug that acts as a potent agonist for the cannabinoid receptors which produces subjective effects somewhat similar to that of cannabis with a short duration and an emphasis on intense physical sensations. There is very little information regarding the pharmacology of this compound within the scientific literature. Despite this, however, it is available for sale as a grey area research chemical through online vendors.
