Cannabis/Medical Marijuana, Psychoactive/Psychedelic Research
Our goal is to provide you with the latest accurate, unbiased published scientific research from reliable sources to help you make the best decisions regarding your health and wellness. You will find nearly 4,000 articles in 12 categories covering a wide variety of issues. This includes over 500 articles on cannabis, the endocannabinoid system, psychoactive, psychedelic and medical/recreational/alternative drug research.
We present in an agnostic format. The information is in chronological order from the past two decades, to the extent possible.

Articles are in chronological order, with occasional exceptions.
Crystals of N,N¬-dimethyltryptamine (DMT) imaged with polarizing microscopy. DMT is the active ingredient in the hallucinogenic drug ayahuasca. New studies from UC Davis using a rat model show that 'microdosing' or taking small doses of a psychedelic drug that do not cause hallucinations may have beneficial effects for mental health.

To produce cannabinoids in yeast (Saccharomyces cerevisiae), UC Berkeley synthetic biologists first engineered yeast's native mevalonate pathway to provide a high flux of geranyl pyrophosphate (GPP) and introduced a hexanoyl-CoA biosynthetic pathway combining genes from five different bacteria. They then introduced Cannabis genes encoding the enzymes involved in olivetolic acid (OA) biosynthesis, a previously undiscovered prenyl transferase enzyme (CsPT4) and cannabinoid synthases. The synthases converted cannabigerolic acid (CBGA) to the cannabinoid acids THCA and CBDA, which, upon exposure to heat, decarboxylate to tetrahydrocannabinol (THC) and cannabidiol (CBD), respectively.

By studying the genome of a kind of octopus not known for its friendliness toward its peers, then testing its behavioral reaction to a popular mood-altering drug called MDMA or 'ecstasy,' scientists say they have found preliminary evidence of an evolutionary link between the social behaviors of the sea creature and humans, species separated by 500 million years on the evolutionary tree.
