Ibuprofen Kills THC Buzz – Suppressing Marijuana Memory Loss


Yesterday, the Los Angeles Times ran a story regarding Alzheimer’s patients – and how they might benefit from combining marijuana’s cannabinoids with a “side of ibuprofen” as a “buzz killing RX for Alzheimer’s.” The article explained how new research has identified ibuprofen as being beneficial when used in conjunction with tetrahydrocannabinol – more commonly referred to as THC – to eliminate medical marijuana’s collateral damage…universally known as “The high.”

The times article pointed to a new study that was recently published in the Journal Cell, which explained a couple of things. First, why common anti-inflammatory drugs like ibuprofen and other prescription analgesics have the ability to blunt out marijuana’s high – suppressing the negative cognitive effects. Second, that getting high on pot to chill out, stunts the growth of the tendrils that lash brain cells together, while weakening memory and cognitive processing functions. And that the bundled buzz of effect-and-side-effect seemed to be inseparable.

Yet, as it turns out, it can be separated, and the unwanted high can be killed, by simply suppressing the induction of cyclooxygenase-2 (COX-2), a multifaceted neurochemical process typically set off by inflammation: “Add a COX-2 inhibitor to the mix — or even a non-selective COX inhibitor such as ibuprofen — and the anti-inflammatory effects of THC remain. The “buzz,” the lethargy and negative cognitive effects of long-term use, however, are extinguished.”


Marijuana has been used for thousands of years as a treatment for medical conditions. However, untoward side effects limit its medical value. Here, we show that synaptic and cognitive impairments following repeated exposure to Δ9-tetrahydrocannabinol (Δ9-THC) are associated with the induction of cyclooxygenase-2 (COX-2), an inducible enzyme that converts arachidonic acid to prostanoids in the brain. COX-2 induction by Δ9-THC is mediated via CB1 receptor-coupled G protein βγ subunits. Pharmacological or genetic inhibition of COX-2 blocks downregulation and internalization of glutamate receptor subunits and alterations of the dendritic spine density of hippocampal neurons induced by repeated Δ9-THC exposures. Ablation of COX-2 also eliminates Δ9-THC-impaired hippocampal long-term synaptic plasticity, working, and fear memories. Importantly, the beneficial effects of decreasing β-amyloid plaques and neurodegeneration by Δ9-THC in Alzheimer’s disease animals are retained in the presence of COX-2 inhibition. These results suggest that the applicability of medical marijuana would be broadened by concurrent inhibition of COX-2.


About Author

Born in Long Beach, raised on the central coast: I surf, dab, burn, and blog – though not necessarily in that order. I'm a husband, a father and a lifelong consumer of connoisseur grade weed. I don't drink alcohol or consume any other "drugs." I consider myself to be living proof that weed is not a gateway drug. If it were, I'd be in some serious trouble. Instead, as a 50-year-old ex-realtor that has been smoking weed for nearly 80% of my life (just did the math) ... I can only say, marijuana is safer than prescription pills or alcohol could ever hope to be for calming what stirs the savage beast.

  7. With havin so much content and articles do you ever run into any issues of plagorism or copyright violation?
    My site has a lot of unique content I’ve either written myself or outsourced but it looks like a
    lot of it is popping it up all over the web without my agreement.
    Do you know any solutions to help prevent content from being stolen?
    I’d really appreciate it.

  9. certainly like your web-site but you have to check the spelling on quite a few
    of your posts. Many of them are rife with spelling problems and I to find it very bothersome to inform
    the reality nevertheless I’ll surely come again again.
