Cannabis Use and Executive Function

In pop culture, perhaps because cannabis is often placed in the same group as other recreational substances, stoners get a bad rap for being slow, under-performers. In the now-famous film Fast Times at Ridgemont High, one of the main characters, Jeff Spicoli, typifies the surfer/stoner as perceived by a large swath of society; he’s essentially an airhead. This type of media portrayal has given the population at large the idea that cannabis is not beneficial for long term mental health. To this degree, almost every medical cannabis user may experience the concern of a well-meaning friend who asks, “That can’t be good for you over time, right?” This is a good question for someone first exposed to any new medicine. Patients should be aware that even the most documented pharmaceutical medicines can be dangerous and misprescribed. As a result, everyone should be vigilant about the effect of taking a new medicine. However, as we’ve covered in previous articles, we’re seeing no long-term irreversible effects statistically. The idea that cannabis is somehow destroying the machinery of the brain long-term is patently false. A more plausible argument might be that cannabis re-directs mental traffic. Sadly, anti-cannabis proponents have latched onto studies that give incomplete results. For instance, it may be true in one test that cannabis users on average perform more slowly. Researchers may then go on to find that when the same test population is weeded of heroin users, the negative effects disappear and all groups perform equally. In other words,…

Does Long Term Cannabis Use Make You Dumb?

I vape cannabis several times a day and have no intentions of stopping anytime soon. It’s never slowed my work ethic or turned me into a zombie. Instead, I feel more creative and at peace. I don’t have any life threatening health conditions or chronic pain, and I’ve never been one to take a lot of pharmaceuticals. However, since I’m not a “hippy” by any means, I tend to have a lot of non-cannabis-using friends who occasionally ask me about my frequent cannabis use. Invariably, the question that always comes up is, “…do you think that stuff rots your brain over time? I heard it makes people dumb if they use it too much…” If you’re open about cannabis use, you’ll probably encounter this conversation at least once. Culturally, we’re used to the image of a stoner-burnout, a guy stuck in the 70’s that handles life like Jeff Bridges’ character in The Big Lebowski. We look at these people and we secretly wonder to ourselves, “did smoking cannabis all day every day make them this way? Will I be like that if I continue to use cannabis?” When we talk about the safety of cannabis, we’re really talking about quite a few things. First, there are the things that we know as facts. Fact: It’s damn near impossible to overdose on cannabis. The amount of THC that would be needed to cause an overdose is such a large quantity that the volume alone makes it difficult to do. For instance,…
