Summary
1B-LSD is an N1-acylated prodrug that is rapidly hydrolyzed in vitro and in vivo to LSD via CYP1A2 and CYP3A4 enzymes. Animal studies show approximately 14% the potency of LSD by weight; blotters marketed at 100 ug 1B-LSD produce subjective effects comparable to 75-100 ug LSD in many users. Because it is a prodrug, CYP1A2/3A4 inhibitors or inducers could alter intensity and onset. Very limited human safety data; treat with the same caution as any novel research chemical. Use harm reduction practices including test kits, appropriate set and setting, and proper hydration.
