The study heated Cannabis sativa extracts at 80, 95, 110, 130, and 145 °C for up to 60 minutes and measured acidic and neutral cannabinoids with an advanced UHPSFC/PDA‑MS lab method. Concentrations changed in an exponential way, which fits a first‑order (or pseudo‑first‑order) reaction model. The team calculated rate constants…

Many studies reported that at least some participants had better sleep, but very few studies focused only on people with insomnia and most…
This small two-phase trial tested single oral doses of the Δ8 form of THCV (placebo and 12.5, 25, 50, 100, 200 mg) in healthy adults and followed participants for up to 8 hours. Most side effects were mild, some doses showed a possible short-term improvement in a sustained-attention test, and…
