Does CBD cross the blood brain barrier?

CBD, while not psychotropic, also modulates immune function, but its mechanism of action appears to differ from that of THC. Since both compounds are highly lipophilic, they readily passage the blood-brain barrier and access the central nervous system.

Does CBD mess with your brain?

THC, the cannabinoid associated with a psychotropic high, is intoxicating — CBD is not. In reality, psychoactive chemicals act on the central nervous system (CNS) and alter brain function. As a result, they cause temporary changes in consciousness, behavior, mood, or perception.

What type of drugs can cross the blood brain barrier BBB?

Most drugs in clinical use to date are small, lipid soluble molecules that cross the BBB by transmembrane diffusion. However, many drug delivery strategies in development target peptides, regulatory proteins, oligonucleotides, glycoproteins, and enzymes for which transporters have been described in recent years.
