Does vaping Cannabis as an adolescent damage brain activity like smoking does?


I’m currently 16 years of age and I am extremely dedicated to my academic and intellectual performance, but I have several chronic mental health disorders, the worst of which being panic disorder and social anxiety disorder. I’ve tried using benzodiazepines, but they impair my ability to think properly, so I can’t use them at work. I find my medical Cannabis does not have this annoying effect, making me able to focus and work well on my schoolwork and job while still being able to cope with my anxiety. I’m just concerned what the long term effects of vaping Cannabis are, could anyone clarify whether vaping Cannabis at a young age lowers the IQ like smoking does? Thank you all so much!

    Well studies show that it can damage brain growth but I believe that was with combustion but I could be wrong. Another factor we have to consider is how often do you find yourself smoking?

    The link between marijuana and IQ isn’t necessarily as solid as many claim. You should be aware that “correlation alone does not imply causation”. What that means is, just because two things are seen together does not mean one caused the other. The classic example is ice cream sales and drowning. As ice cream sales increase so do drownings. That doesn’t mean the ice cream cause the drownings though. It’s actually because more people go swimming when it’s hot and they also buy more ice cream. So the temperature outside is actually what caused it not the ice cream.

    The [[Marijuana Dunedin Study]]( is the one being used to show proof of marijuana’s detrimental effect. What it does show is a correlation. Other Studies have contradicted these findings.

    >Correlations between cannabis use and IQ change in the Dunedin cohort are consistent with confounding from socioeconomic status

    TL;DR: The correlation seen in the Dunedin Study may be related to poverty rather than marijuana itself.

    >CONCLUSIONS: Short-term cannabis use in adolescence does not appear to cause IQ decline or impair executive functions, even when cannabis use reaches the level of dependence. Family background factors explain why adolescent cannabis users perform worse on IQ and executive function tests.

    >Regular cannabis use shrinks the brain but increases the complexity of its wiring, a study has found.

    >The scans revealed that smoking cannabis every day was associated with shrinkage in the orbitofrontal cortex (OFC) region of the brain, which is involved in mental processing and decision making.

    >“The results suggest increases in connectivity, both structural and functional that may be compensating for grey matter losses. 

    >After six to eight years of continually taking cannabis the increases in structural wiring declined, but users continued to display higher connectivity than non-users.

    >This may explain why chronic, long-term cannabis users appeared to be “doing just fine” despite having smaller OFCs, said co-author Dr Francesca Filbey, also from the University of Texas.

    Even some of the IQ loss Studies have shown some contradictory data:

    >The comparison of the IQ difference scores showed an average decrease of 4.1 points in current heavy users (p < 0.05) **compared to gains in IQ points for light current users (5.8)**, former users (3.5) and non-users (2.6).

    >INTERPRETATION: Current marijuana use had a negative effect on global IQ score **only in subjects who smoked 5 or more joints per week**. A negative effect was not observed among subjects who had previously been heavy users but were no longer using the substance. We conclude that marijuana does not have a long-term negative impact on global intelligence.

    The same correlation also exists for untreated depression:

    >Untreated mental disorders cause shrinkage of key brain areas

    >Results:  Compared with controls, patients showed significantly more decline in gray matter density of the hippocampus, anterior cingulum, left amygdala, and right dorsomedial prefrontal cortex. Patients who remitted during the 3-year period had less volume decline than nonremitted patients in the left hippocampus, left anterior cingulum, left dorsomedial prefrontal cortex, and bilaterally in the dorsolateral prefrontal cortex.

    Edit: Vaping might be healthier for the lungs but I don’t think it’ll have much effect on brain changes.
