A new study, published in Neurobiology of Disease, suggests that daily consumption of cannabis in teens can cause depression and anxiety, and have an irreversible long-term effect on the brain.
I think the methodological flaw is obvious here. Unless they measured the teens before they ever smoked marijuana, they have no base line to judge against. It's quite likely that teens, who suffer from depression and anxiety in greater numbers than the overall population, are more attracted to marijuana for the very reason that it INCREASES seratonin transmission.
So rather than saying that marijuana is the CAUSE of depression and anxiety, once again it is the vilified marijuana that is reliving the symptoms of their depression and anxiety, not causing it!
So their erroneous assumption completely invalidates their conclusions! Fortunately the article sets it right: it says, this study, "suggests that daily consumption of cannabis in teens can cause depression and anxiety..."
The operative word is "suggests", cause they haven't (and can't) prove the cause of depression & anxiety because it was already there before they used marijuana.
Here's another study from a couple of years ago that shows that low doses of cannabis INCREASES the level of serotonin and maybe useful for treating depression. However this article says:
"Excessive cannabis use in people with depression poses high risk of psychosis."
Notice how in the past they assumed the depression is PRE-EXISTING, not an effect of the cannabis. But now that has changed as the propaganda war against marijuana has heated up.
Let's not put the cart before the horse here. Marijuana isn't causing Depression and Anxiety. Those are pre-existing conditions. In some circumstances marijuana can exacerbate these pre-existing conditions. It only proves that marijuana is NOT for everyone!
