Cannabis Compound Identification
Common NameEthylmethylpyrene
DescriptionEthylmethylpyrene belongs to the class of organic compounds known as pyrenes. Pyrene is a polycyclic aromatic hydrocarbon (PAH) consisting of four fused benzene rings, resulting in a flat aromatic system. This colourless solid is the smallest peri-fused PAH (one where the rings are fused through more than one face). Pyrene results from the incomplete combustion of organic compounds, in a wide array of conditions. The aromaticity and peri-fused condition of pyrene make it a more stable combustion product than its isomer fluoranthene. PAH metabolism occurs in all tissues, usually by cytochrome P-450, specifically by its associated enzymes CYP1A1 and CYP1B1 (PMID: 14720319 ). These enzymes metabolize PAH's into their toxic intermediates. The metabolites of pyrene, such as phenols, quinones, and dihydrodiols, can all be conjugated to glucuronides and sulfate esters; the quinones also form glutathione conjugates. PAHs are generally considered as cancerogenic to varying degrees. Ethylmethylpyrene is formed during the combustion of cannabis and is therefore a constituent of cannabis smoke ( Ref:DOI ).
