E configuration Memes

The ultimate chemical identity crisis! This molecular structure is LSD (lysergic acid diethylamide), but the meme cleverly plays on the double meaning of "E" - the street name for MDMA (ecstasy) versus the stereochemistry designation in organic chemistry. Those dotted bonds represent different spatial orientations that can make a molecule either biologically active or completely useless. Chemistry students staring at this during finals week are probably thinking "I'd rather just take the other E and forget this exam exists." The struggle between recreational chemistry and academic chemistry has never been more relatable!
