JWH-398 is an analgesic compound belonging to the naphthoylindole family, functioning as a cannabinoid agonist with activity at both the CB1 and CB2 receptors. It exhibits mild selectivity for CB1, demonstrating a Ki of 2.3 nM while registering 2.8 nM at CB2 receptors. The EMCDDA identified this synthetic chemical as an ingredient in three distinct “herbal incense” products acquired from online shops between February and June 2009. The compound’s discovery is credited to John W. Huffman, whom it is named after.
In the United States, JWH-398 is categorized as a Schedule I controlled substance.

1. What is JWH-398?
JWH-398 is a synthetic compound from the naphthoylindole family, known for its analgesic properties. It acts as a cannabinoid agonist, affecting the CB1 and CB2 receptors.
2. How does JWH-398 interact with cannabinoid receptors?
JWH-398 binds to cannabinoid receptors, specifically the CB1 and CB2 receptors. This interaction influences various physiological and psychological processes.
3. Is JWH-398 selective for a specific cannabinoid receptor?
JWH-398 exhibits mild selectivity for the CB1 receptor with a Ki (binding affinity) of 2.3 nM and registers a Ki of 2.8 nM at CB2 receptors. This indicates a slight preference for CB1, but it interacts with both receptor types.
4. What is the history of JWH-398’s discovery?
John W. Huffman, a prominent figure in cannabinoid research, discovered JWH-398. The compound bears his name in recognition of his contributions to this field.
5. Where was JWH-398 found in 2009?
In 2009, JWH-398 was identified as an ingredient in three “herbal incense” products purchased from online shops. This discovery raised awareness about its presence in certain products.
6. What is the legal status of JWH-398 in the United States?
In the United States, JWH-398 is classified as a Schedule I controlled substance. This categorization places it under strict legal control due to its potential misuse and abuse.
7. Are there potential medical applications for JWH-398?
While JWH-398’s cannabinoid properties suggest possible medical applications, its regulatory status and potential risks associated with synthetic compounds have limited its exploration in the medical field. Researchers and authorities prioritize safety in the evaluation of such substances.
