Dimethylheptylpyran

Dimethylheptylpyran (DMHP) is a synthetic analogue of THC, a compound found in cannabis. It was first synthesized in the 1940s by the American chemist, Roger Adams, and his team at the University of Illinois.

History

DMHP was developed as part of a research project by the United States military during the 1960s. The aim of the project was to create a non-lethal incapacitating agent. The compound was given the code name EA 2233 and was one of the most potent compounds tested.

Chemistry

DMHP is a derivative of THC, the main active ingredient in cannabis. It is a complex molecule with a seven-carbon side chain, making it 30 times more potent than THC. The compound is also known as 3-(1,2-dimethylheptyl)-6a,7,10,10a-tetrahydro-1-hydroxy-6,6-dimethyl-6H-dibenzo[b,d]pyran-9-carboxylic acid methyl ester.

Effects

The effects of DMHP are similar to those of THC but are much more potent and long-lasting. The compound has a half-life of 20-48 hours, compared to the 2-3 hours of THC. The effects include euphoria, altered perception, and severe sedation.

Legal status

DMHP is classified as a Schedule I controlled substance in the United States, meaning it has a high potential for abuse and no accepted medical use.
