Arecoline
Methyl 1,2,5,6-tetrahydro-1-methylnicotinate
stimulant

Pyridine alkaloid acting as a partial muscarinic acetylcholine receptor agonist. The primary psychoactive constituent of betel/areca nut, producing mild stimulation, warmth, and a sense of well-being alongside well-documented carcinogenic risk to oral tissues with chronic use.

Asarone
sedativestimulant

Phenylpropanoid found in Acorus calamus and Asarum species. Mechanism remains incompletely understood; mild psychoactive, sedative, and tonic effects have been described historically. β-asarone, a related isomer, is classified as a probable carcinogen and is the reason calamus from Indian-strain plants is regulated as a food additive.

1,3,7-Trimethylxanthine
stimulant

The most widely consumed psychoactive substance on Earth. Acts primarily as a competitive antagonist of adenosine receptors, indirectly raising dopamine, norepinephrine, and acetylcholine signaling — producing wakefulness, alertness, and mild euphoria.
