<p>I think the arguments about which is worse for a teen brain are specious. </p>
<p>You have a developing part of your body. In what universe does it sound like a good idea to expose a developing part of your brain to a substance which actively changes the chemistry of your brain. </p>
<p>Teenage brains are engaged in active learning which happens with synaptic growth and pruning. If during the phases of active growth of your prefrontal cortex (teen and young adult years) you regularly expose your brain to cannabis, or to alcohol… your brain learns… to be addicted. </p>
<p>Cannabis impacts memory function for up to a week after use. If I am paying $60,000 for my child to attend university, I am going to think that cannabis usage is not a great idea, actually. The article specifically says they looked at brain tissue… not function. For me, function and performance seem relevant!</p>
