Cannabinol
Occurrence: Occurs on Cannabis naturally in small amounts. Moreso on Indica. This also is what THCa will naturally turn to over time. More plentiful on mature plants.
Psychoactive: Lightly - Smoking CBN alone produces more of a buzz
Effects: Sleepy, giggly.
Potency: Weak, but still intoxicating. Especially as this is only the sleepy bits of weed.
Discovery: 1896
Notes: Mixing some CBN into a concentrate is a great way to make a “night cap” variant of that concentrate. This is useful as many find concentrates don't make them as sleepy. A few concentrate making methods will not properly extract CBN, thus, you may have to add it.
