    Nootropic Supplement Cannabinoid

    Summary

    Cannabigerol (CBG) is a non-intoxicating minor cannabinoid. The plant first makes its acid form, CBGA, which is the biosynthetic precursor of THC, CBD and CBC — young plants are richest in it, and most harvested cannabis contains well under 1%. It has only weak affinity for CB1 and CB2 receptors and does not produce a high; in vitro it acts at other targets (alpha-2 adrenoceptor agonism, 5-HT1A antagonism), and human evidence for the calming and focus effects it is marketed on is thin. Sold as hemp-derived oils, isolates and "CBG flower".

    Dose basis. Ranges are largely based on market/user reports and early pilot work; commercial preparations vary in purity and bioavailability. Lipophilic cannabinoids like CBD show higher exposure with high-fat meals; CBG likely behaves similarly—titrate cautiously if co-administered with fat-rich meals. Start low, go slow. Avoid swallowing for 60–120 seconds to improve buccal absorption. Product viscosity and excipients (e.g., MCT, ethanol) meaningfully affect uptake. (Dose figures and this note are from Drugs.Wiki.)

    The PsychonautWiki Journal logging app doesn't include every substance. To track CBG there, start adding an ingestion, search for the name, and choose to add it as a custom substance. Paste these values:

Note: ranges are harm-reduction guidance, not a prescription. Start low, go slow, and test your substances.

    Tip: for quicker logging you can also add a Custom Unit in the app, e.g. common dose ~ 27.5 mg (Oral).

    The app keeps custom substances simple, so the full dose ranges live in the description text above. Ranges are harm-reduction guidance, not a prescription.
