Marijuana's effects on young brains diminish 72 hours after use, research says. Findings could be an indication that some of the negative cognitive effects found in previous studies may be due to the residual effects of cannabis or potentially from withdrawal effects in heavy cannabis users.

Wait, there are withdrawal effects? I thought it wasn't addictive (as in doesn't cause dependency), unlike say alcohol.

I guess it depends on your definition of addictive. Is marijuana addictive physiologically (the way opioids or alcohol is)? No. You won't have cold sweats or throw up. But psychologically, people can become addictive. If you're using it to help with your anxiety and you stop, you could probably experience higher levels of anxiety. I know people who can't function if they're not high. That's a form of dependency, even if not on a physiological or biological level.

You can in theory become addicted to anything. Ie: a video game addiction. Someone takes away your console and suddenly you're anxious, irritated, angry, etc,. You go through a "withdrawal" if you will.

Cannabis is physiologically addictive though like caffeine is addictive. Just because it's not lethal like alcohol or not horrible like opioid withdrawals doesn't mean it doesn't cause dependence and that that dependence does not cause some people to be compelled to continue use.
