Ease into sleep or balance out an over-caffeinated afternoon with the uniquely soothing effects of this microdose sublingual tablet. Each Tablingual contains 5 mg of CBN, and it takes effect in 5–20 minutes and lasts 1–2 hours. CBN is a mildly psychoactive cannabinoid that is formed as a result of the degradation of THC. CBN is often described as a mild analgesic and may be used as a potential sleep aid.
