Diabetes and Marijuana: Marijuana Users Could Have Better Blood Sugar


A study that might answer some questions about diabetes and marijuana appeared online  this week in the American Journal of Medicine:  The Impact of Marijuana Use on Glucose, Insulin, and Insulin Resistance among US Adults.  The study is the first to investigate the relationship between marijuana use and fasting insulin, glucose, and insulin resistance.

Cannabis as illustrated in Köhler’s Medicinal Plants book from 1897

The American Journal of Medicine’s blog reports, “Participants who reported using marijuana in the past month had lower levels of fasting insulin and HOMA-IR [insulin resistance] and higher levels of high-density lipoprotein cholesterol (HDL-C). These associations were weaker among those who reported using marijuana at least once, but not in the past thirty days, suggesting that the impact of marijuana use on insulin and insulin resistance exists during periods of recent use. Current users had 16% lower fasting insulin levels than participants who reported never having used marijuana in their lifetimes.

Large waist circumference is linked to diabetes risk. In the current study there were also significant associations between marijuana use and smaller waist circumferences.”

The blog also quotes an author of the study, Elizabeth Penner, MD, MPH, who said that after subjects with a diagnosis of diabetes were excluded, the associations between marijuana use and insulin levels, HOMA-IR, waist circumference, and HDL-C were similar and remained statistically significant.

In summary, the study concludes three things about marijuana use:  It was associated with lower levels of fasting insulin and insulin resistance, and smaller waist circumference.  So marijuana users could have better blood sugar levels.

Does this study mean marijuana is safe for people with diabetes?  No.  This study is not a green light to pass the dutchie.  There’s not enough evidence here to conclude that marijuana and diabetes are a good combination.   But the study is significant because it’s a first, and it suggests that more research is needed to explore future treatments using the marijuana plant’s compound active ingredient, tetrahydrocannabinol, or THC.

I am a type 1 diabetic and I have smoked weed for years, I know when my sugar is high it definately helps lower my sugar without taking any insulin, which is nice. I feel like even though you get the munchies it still keeps my sugar lower and I have been diabetic for 26 years and have smoked weed for 18 years. I think that it is great for type one diabetics who need better control over their blood sugar. It should be a qualifying disease for medical marijuana use in all qualifying states!!!

Hi. I am type 2 diabetic and have severe chronic pains. The pain brings my mood(s) down and I have turned “grumpy” (usually the life of the party before chronic pain). I have never smoked marijuana until I was asked to test it out a few weeks ago to find out what it goes to my moods and diabetes. This is what I’ll share…. My pain has come down really low, my moods are back to happier, my sugars go up (from 80-90 to 140-200+) and my blood pressure has raised also. I found that having healthier snacks around me… Read more »

Interesting blog about ‘da chronic, but I go for the most obvious factors first. Like the role of the major ingredients in natural food in healthy cellular functions. Or how micronutrient is stripped out of processed foods to create addiction. Or how fructose is linked to growth of cancer cells. The most important factor in health is the food we eat. After all, our bodies are indeed made of Earth materials! http://TheInsulinProject.ca
