(d)-Lysergic acid amide (LSA) or ergine is a psychoactive compound structurally similar to (d)-Lysergic acid diethylamide or (LSD) however it is a much weaker hallucinogen. Pure or synthetic LSA is a controlled substance in most countries because it is so similar to LSD. However plants that contain LSA are uncontrolled. Seeds from a plant known as Morning Glory are psychoactive due to LSA. Other sources of LSA include Hawaiian Baby Woodrose seeds.
I took some LSA and felt buzzy
